Comparative Leaf Water Absorption Between Chaparral Island And Mainland Taxa: A Common Garden Experiment, Humera S. Mirza, Lauren M. Tucker, Rodrigo Méndez-Alonzo, Edward G. Bobich, Frank W. Ewers
Comparative Leaf Water Absorption Between Chaparral Island And Mainland Taxa: A Common Garden Experiment, Humera S. Mirza, Lauren M. Tucker, Rodrigo Méndez-Alonzo, Edward G. Bobich, Frank W. Ewers
Aliso: A Journal of Systematic and Floristic Botany
In California and other Mediterranean-type ecosystems, island species are typically exposed to more fog but less rain than mainland species. Because adaptations to absorb water from fog may conflict with those to minimize water loss, we hypothesized that island species should have greater fog absorption than their mainland congeners due to foliar uptake but at the cost of modifying other leaf structural and functional traits. To determine whether foliar water absorption is an adaptation to insularity, we compared seven physiological and anatomical leaf traits between congeneric island and mainland species of two genera, Ceanothus and Arctostaphylos, in a common …

A Vascular Flora Of The South Fork Tule River, Southern Sierra Nevada, Tulare County, California, Jessica M. Orozco
A Vascular Flora Of The South Fork Tule River, Southern Sierra Nevada, Tulare County, California, Jessica M. Orozco
Aliso: A Journal of Systematic and Floristic Botany
I conducted a floristic study of the South Fork Tule River watershed, located in the southern Sierra Nevada in Tulare County, California. The primary objectives of this floristic study were to document and catalogue all vascular plant taxa that occur in the watershed, describe the plant communities, analyze the flora and its affinities with other areas, and establish a herbarium for the Tule River Indian Reservation. The upper reaches of the South Fork Tule River originate on the western slope of Slate Mountain in the Sequoia National Forest and drain west through the Tule River Indian Reservation into Lake Success. …
Forty Years Of Change In Piute Cypress (Hesperocyparis Nevadensis), A Rare California Tree, After Frequent Fire And Drought, Amarina Wuenschel, Jim A. Bartel, Alexis Bernal
Forty Years Of Change In Piute Cypress (Hesperocyparis Nevadensis), A Rare California Tree, After Frequent Fire And Drought, Amarina Wuenschel, Jim A. Bartel, Alexis Bernal
Aliso: A Journal of Systematic and Floristic Botany
Piute cypress (Hesperocyparis nevadensis) is a rare cypress species endemic to the Lake Isabella region in the southern Sierra Nevada in California. Piute cypress groves have not been quantitatively studied in the last 40 years and with recent fires (some in short succession) and observed mortality, we had questions surrounding conditions in groves recovering from fire compared to other groves with no recorded fire histories. Piute cypress rarely survive fire and are obligate seeders with serotinous cones and, as such, require sufficient time after fire to grow to reproductive maturity to be able to withstand future fire. We …

Aliso: A Journal of Systematic and Floristic Botany
Sherwin Carlquist (1930–2021) was an internationally respected and distinguished botanist who held faculty positions in botany at California Botanic Garden, Claremont Graduate University and Pomona College between 1956 and 1992. His legacy includes major scholarly contributions to plant systematics, plant anatomy, especially wood anatomy, island biogeography, evolutionary and ecological reasoning, and a prolific publication record. A loose collection of paragraphs by those who interacted with him addresses Carlquist's tremendous botanical output, teaching, mentorship, scientific scholarship, and his roles as a colleague and friend.
A Vascular Flora Of The Selkirk Mountains, Bonner And Boundary Counties, Idaho, Harpo Faust, Ben Legler, David C. Tank
A Vascular Flora Of The Selkirk Mountains, Bonner And Boundary Counties, Idaho, Harpo Faust, Ben Legler, David C. Tank
Aliso: A Journal of Systematic and Floristic Botany
The vascular flora described here covers ~2295 square kilometers (~886 square miles) of the Selkirk Mountains that lie in the Idaho Panhandle, covering an elevational range of 540–2330 m (1770–7670 ft). The majority of the mountain range is underlain by granitic rock of the Kaniksu Batholith, and is diversified by the rich glacial history of the Panhandle. The study area contains multiple pockets of alluvial and glacial deposition that serve as specialized habitat for present-day floristic diversity within the range. The Idaho Selkirks are part of the Northern Rocky Mountains and have floristic influences from the Pacific coast, boreal north, …
A Question Of Priority: Pterospora Andromedea Nuttall Vs. Monotropa Procera Torrey Ex Eaton (Monotropoideae, Ericaceae), Gary D. Wallace
A Question Of Priority: Pterospora Andromedea Nuttall Vs. Monotropa Procera Torrey Ex Eaton (Monotropoideae, Ericaceae), Gary D. Wallace
Aliso: A Journal of Systematic and Floristic Botany
Clarity is lacking on the priority of the names Pterospora andromedea Nutt. versus Monotropa procera Torr. ex Eaton, both of which were published in 1818, and the suggested clear answer may not be the correct answer. Taxonomic Literature, second edition, provides a publication date of 14 July 1818 for Nuttall’s Genera of North American Plants and a publication date of June 1818 for Eaton’s Manual of Botany ed. 2. However, upon closer scrutiny, the situation is more complex. The sources for these publication dates are discussed in order to trace the likely sequence of events leading up …

Vascular Plants Of Northern Death Valley National Park (Death Valley, Last Chance Range, And Eureka Valley), Inyo County, California, Hester L. Bell, Sarah J. De Groot, Steve E. Schoenig
Aliso: A Journal of Systematic and Floristic Botany
The northern portion of Death Valley National Park closely (but not entirely) corresponds to the northernmost portion of the Mojave Desert in California. From 2014 through 2019 we surveyed the vascular plants in the Eureka Valley, northern Last Chance Range, and northern Death Valley. This study area covers 1735 sq km and ranges in elevation from 810 to 2577 m; it contains the tallest sand dunes in California, a calcium-rich mountain range, and alkaline seeps. These features provide specialized habitats for narrowly and regionally endemic plants. Fossil data from packrat middens suggest that the local climate has become warmer and …

A list of bryophytes occurring naturally in northern Death Valley National Park is presented. So far, 41 taxa have been documented, representing seven families and 24 genera. One species, Jaffueliobryum wrightii, is considered rare by the California Native Plant Society.
Justicieae Ii: Resolved Placement Of Many Genera And Recognition Of A New Lineage Sister To Isoglossinae, Lucinda A. Mcdade, Carrie A. Kiel, Thomas F. Daniel, Iain Darbyshire
Justicieae Ii: Resolved Placement Of Many Genera And Recognition Of A New Lineage Sister To Isoglossinae, Lucinda A. Mcdade, Carrie A. Kiel, Thomas F. Daniel, Iain Darbyshire
Aliso: A Journal of Systematic and Floristic Botany
We present phylogenetic results for Justicieae, the largest of the major lineages of Acanthaceae. With 300% more sequence data and a similarly increased but also more geographically representative taxon sample compared to the only previous study of the lineage as a whole, we confirm the existence of the Pseuderanthemum Lineage, Isoglossinae, the Tetramerium Lineage and the Justicioid Lineage. To the last three lineages, we add a number of taxa with the goal of advancing our knowledge of genera (e.g., Isoglossa, Rhinacanthus) and of geographic areas (e.g., Malagasy and Asian Acanthaceae). These added taxa are accommodated within the phylogenetic …
Vascular Flora Of Adobe Valley And Surrounding Hills, Mono County, California, Sophie E. Winitsky
Vascular Flora Of Adobe Valley And Surrounding Hills, Mono County, California, Sophie E. Winitsky
Aliso: A Journal of Systematic and Floristic Botany
Adobe Valley and the Adobe Hills lie east of the Sierra Nevada in Mono County, California, and are within the Great Basin Floristic Province. The flora of Adobe Valley and the surrounding hills is influenced by the Great Basin Desert to the east, the Sierra Nevada to the west and the northern Mojave Desert to the south. Adobe Valley is surrounded by the Adobe Hills, Benton Range and Glass Mountain region, creating a circular closed basin with many small tributaries feeding into it. This topography contributes to the creation of a rare wetland complex, including alkali meadows, marshes, and lakes …
Wood Anatomy Of Argophyllaceae (Asterales): Adaptation In A Small Clade, Sherwin Carlquist, Mark E. Olson
Wood Anatomy Of Argophyllaceae (Asterales): Adaptation In A Small Clade, Sherwin Carlquist, Mark E. Olson
Aliso: A Journal of Systematic and Floristic Botany
Argophyllaceae (Argophyllum, 14 spp.; Corokia, 6 spp.; Lautea, 1 sp.), are shrubs that occur in the southwestern Pacific and eastern Australia. They occur in habitats where moisture is relatively common but dry days and mild frost may occur. The woods of these genera show enough distinctive features to justify their grouping in a single family: perforation plates with 10–20 bars, vessel elements narrow and numerous per mm2, imperforate tracheary elements about 50% longer than the vessel elements, axial parenchyma scarce, diffuse, multiseriate rays narrow and heterocellular (upright cells common in uniseriate rays), crystals absent, …

Plantae Coulterianae: Thomas Coulter’S Californian Exsiccata, Gary D. Wallace
Aliso: A Journal of Systematic and Floristic Botany
An account of the extent, diversity, and importance of the Californian collections of Thomas Coulter in the herbarium (TCD) of Trinity College, Dublin, Ireland, is presented here. It is based on examination of collections in TCD, several other collections available online, and referenced literature. Additional information on historical context, content of herbarium labels and annotations is included. Coulter’s collections in TCD are less well known than partial duplicate sets at other herbaria. He was the first botanist to cross the desert of southern California to the Colorado River. Coulter’s collections in TCD include not only 60 vascular plant specimens previously …
Remembering Lee W. Lenz (1915–2019)
Remembering Lee W. Lenz (1915–2019)
Aliso: A Journal of Systematic and Floristic Botany
Known primarily for his systematic work on Iris, Dr. Lee Lenz was also known for his taxonomic revision in other monocotyledonous groups such as Yucca, leading to his recognition of Yucca jaegeriana as distinct from the Joshua tree, Y. brevifolia. He was also involved in breeding horticultural forms from California native plants, such as xChiranthofremontia lenzii, and was credited with developing the first red-flowering iris within the Pacific Coast hybrids. Dr. Lenz was Director of Rancho Santa Ana Botanic Garden (now California Botanic Garden) in Claremont, California, from 1960 to 1983. A table lists his …
“Primitive” Wood Characters Are Adaptive: Examples From Paracryphiaceae, Sherwin Carlquist
“Primitive” Wood Characters Are Adaptive: Examples From Paracryphiaceae, Sherwin Carlquist
Aliso: A Journal of Systematic and Floristic Botany
Why plants rich in plesiomorphic (“primitive”) features are alive today is a question that receives little comment. Apomorphies in angiosperms are often interpreted as valuable adaptations. However, both apomorphies and plesiomorphies can be keyed to ecological and physiological features. If a particular habitat remains little modified for long periods of geological time, plesiomorphic features should theoretically persist. The Bailey-Frost-Kribs correlations (usually between tracheary element length and character states in other wood features), deemed useful in their day, did not include adaptation to ecology, nor did they have the advantages that molecular-based phylogenies bring to us today. Montane cloud forests or …
New Additions To The Flora Of San Nicolas Island, Ventura County, California, Benjamin E. Carter, William F. Hoyer Iii, Jonathan Dunn, C. Matt Guilliams
New Additions To The Flora Of San Nicolas Island, Ventura County, California, Benjamin E. Carter, William F. Hoyer Iii, Jonathan Dunn, C. Matt Guilliams
Aliso: A Journal of Systematic and Floristic Botany
Ongoing collecting efforts on San Nicolas Island have substantially increased the number of plant species documented from the island. Here we report thirty-one plants previously unrecorded from the island. The list includes six eudicots, one monocot, four liverworts and twenty mosses. Five of these species are understood to be introduced on San Nicolas and the remainder are believed to be native. The native vascular plants are Logfia filaginoides, Cistanthe maritima and Muhlenbergia microsperma. Of the twenty-four new bryophytes, one—Asterella bolanderi—is the first record from the Channel Islands. Specific ecological and locality information are provided for the …

Vascular Flora Of The Upper Rock Creek Watershed, Eastern Sierra Nevada, California, Joy D. England
Vascular Flora Of The Upper Rock Creek Watershed, Eastern Sierra Nevada, California, Joy D. England
Aliso: A Journal of Systematic and Floristic Botany
The upper Rock Creek watershed is located on the east slope of the Sierra Nevada in Inyo and Mono counties. It is ca. 36.5 square miles (94.5 square km) in area and varies in elevation from 7360 to 13,750 ft (2243 to 4191 m). Quaternary glacial erosion and deposition produced striking landscape features, including alpine fell fields and numerous small lakes. Previous floristic inventories in Rock Creek recorded a combined 396 minimum-rank taxa (species, subspecies, varieties, named hybrids) but were restricted to Little Lakes Valley and the surrounding high areas. An updated, annotated checklist of vascular plants is presented, based …

A Vascular Flora Of The Kiavah Wilderness, Scodie Mountains, Kern County, California, Erika M. Gardner
A Vascular Flora Of The Kiavah Wilderness, Scodie Mountains, Kern County, California, Erika M. Gardner
Aliso: A Journal of Systematic and Floristic Botany
Congress designated the Kiavah Wilderness in 1994 under the California Desert Protection Act. It is located in the Scodie Mountains in Kern County, ca. 24 km (15 mi) east of Lake Isabella and 24 km (15 mi) west of Ridgecrest, and encompasses a total of 137 mi2 (354 km2) with elevations ranging from 1000 to 2200 m (3500–7294 ft). The Wilderness is ecologically important because it occurs in a transition zone between two floristic provinces, the Sierra Nevada of the California Floristic Province and the Mojave Desert of the Desert Province. It is of cultural significance because …
Phylogenetics Of The Borage Family: Delimiting Boraginales And Assessing Closest Relatives, Kristen E. Hasenstab-Lehman
Phylogenetics Of The Borage Family: Delimiting Boraginales And Assessing Closest Relatives, Kristen E. Hasenstab-Lehman
Aliso: A Journal of Systematic and Floristic Botany
The placement of Boraginales, and relationships within the family have remained elusive in modern, broad phylogenetic studies. In order to assess the phylogeny of Boraginales, and specifically to test the sister lineage of the order, a data matrix of the chloroplast markers rbcL, ndhF, and trnL-trnF was assembled from GenBank and de novo sequences (representing 132 new GenBank accessions). Phylogenies inferred using Maximum Likelihood and Bayesian frameworks resulted in identical topologies. Tests for alternative topologies were used to assess whether any of the candidates for sister (Solanales, Gentianales, Lamiales, or Vahlia) to Boraginales could …
Vestured Pits In Echium (Boraginaceae): Island Woodiness Revisited, Sherwin Carlquist
Vestured Pits In Echium (Boraginaceae): Island Woodiness Revisited, Sherwin Carlquist
Aliso: A Journal of Systematic and Floristic Botany
Vestured pits are present on pits of secondary xylem vessels of all studied Echium species, roots as well as stems. Variations in vesturing presence do occur in the genus (across wide circular pit cavities; along margins of elliptical pit apertures; aggregated to various degrees; variously abundant), but these are difficult to define precisely and are related primarily to organography and ecology rather than to the taxonomic system. The Macaronesian species have been reported to form a single clade. Wood anatomical features other than vesturing are also closely keyed to species ecology and, in particular subclades, growth forms. Woodiness, exemplified by …
Impact Of Ground Water Depletion On The Mesquite Community At Edwards Air Force Base, Western Mojave Desert, California, Jonathan E. Campbell, M. Rasoul Sharifi, Philip W. Rundel
Impact Of Ground Water Depletion On The Mesquite Community At Edwards Air Force Base, Western Mojave Desert, California, Jonathan E. Campbell, M. Rasoul Sharifi, Philip W. Rundel
Aliso: A Journal of Systematic and Floristic Botany
Edwards Air Force Base (EAFB) provides a habitat refugium for mesquite woodlands in the western Mojave Desert of the Antelope Valley. Although many mesquite communities in the arid southwest are considered invasive as they reduce the extent of grazing lands, the community at EAFB is composed primarily of large, widely spaced trees that provide food and shelter for local wildlife species and recreational opportunities for base personnel. Unfortunately, the range of these mesquite trees appears to be contracting as mature and old individuals dominate the community. Although anecdotal evidence suggests that the fall in the local groundwater table is responsible …
The Vegetation And Flora Of Edwards Air Force Base, Western Mojave Desert, California, David Charlton, Philip W. Rundel
The Vegetation And Flora Of Edwards Air Force Base, Western Mojave Desert, California, David Charlton, Philip W. Rundel
Aliso: A Journal of Systematic and Floristic Botany
Edwards Air Force Base extends over 121,000 ha in the Antelope Valley of the western Mojave Desert, with much of the area part of a closed endorheic basin that held the Pleistocene Lake Thompson. Notable topographic features are Rogers, Rosamond and Buckhorn dry lakes, while rounded domes and scattered hills are present to the north and east. Elevation gradients are limited, ranging from a low of 690 m to 1044 m near the eastern margin. Diverse communities of saltbush scrub dominate the lower plains, while creosote bush scrub and Joshua tree woodlands are present away from the old lake basin. …

Aliso: A Journal of Systematic and Floristic Botany
The gymnosperm diversity of Aguascalientes, Mexico, is presented. Fifteen species from five genera and three families are reported, two of Coniferales (Cupressaceae and Pinaceae) and one of Gnetales (Ephedraceae). Pinus is the most diverse and abundant genus with seven species. The most abundant species is P. teocote, while P. strobiformis is the scarcest. Juniperus is the next most diverse genus, represented by four species, with J. deppeana the most abundant and J. durangensis the scarcest. Cupressus lusitanica, Taxodium mucronatum and Ephedra compacta are each the sole representatives of their genera. Most conifers occupy the mountainous part of the …
Plant Phenology And Water Relations In A Saline Pan-Dune Mosaic In The Western Mojave Desert, M. Rasoul Sharifi, William N. Brostoff, Philip W. Rundel
Plant Phenology And Water Relations In A Saline Pan-Dune Mosaic In The Western Mojave Desert, M. Rasoul Sharifi, William N. Brostoff, Philip W. Rundel
Aliso: A Journal of Systematic and Floristic Botany
An extensive mosaic of small clay pans and low stable dunes exists within Edwards Air Force Base in the western Mojave Desert of California. This pan-dune ecosystem, positioned between the large Rosamond and Rogers dry lakes on the old Pleistocene lakebed of Lake Thompson, provides an opportunity to study the seasonal patterns in growth and flowering phenology and water relations in a saltbush scrub community dominated by a mix of C3 and C4 species. C3 shrubs initiated vegetative growth in February, with current shoot and leaf production largely ceasing in most species by mid-April. The deeply rooted …
