Evaluating Genetic Variation Of Brassica Tournefortii Gouan Collections Via Microsatellite Marker Analysis, Brian Alfaro, Thomas F. Turner, Diane L. Marshall
Evaluating Genetic Variation Of Brassica Tournefortii Gouan Collections Via Microsatellite Marker Analysis, Brian Alfaro, Thomas F. Turner, Diane L. Marshall
Aliso: A Journal of Systematic and Floristic Botany
Plants can differ in phenotypes, but genetic variation may not always reflect phenotypic differentiation. In this study, we tested if native, invasive and landrace population types of Brassica tournefortii Gouan diverged genetically. We performed this comparison by genotyping individuals derived from our own field collections (invasive populations) and from USDA accessions (plants from the native range and landraces). We used two polymorphic microsatellite loci to analyze allelic diversity (Question 1), genetic differentiation, admixture, inbreeding (Question 2) and evolutionary relationships (Question 3) of three population types and of 17 populations of B. tournefortii. Comparison of allelic diversity indices and observed …

A Vascular Flora Of Ladd Canyon, Santa Ana Mountains, Orange And Riverside Counties, California, Daniel P. Donovan, Amanda E. Fisher
Aliso: A Journal of Systematic and Floristic Botany
The Santa Ana Mountains are a coastal range on the border of Orange and Riverside counties in southern California. Ladd Canyon, covering 18.2 km2 in the Cleveland National Forest, is a botanical black hole relative to the rest of the Santa Ana Mountains because of limited access. It is dominated by chaparral and coastal sage scrub and includes significant knobcone pine (Pinus attenuata) stands and riparian woodland. Features that make it an intriguing area to study include the only serpentine soil in the Santa Ana Mountains, large tracts of habitat that have no recorded fire history, steep …

The Rare, Endangered And Endemic Plants Of The California Floristic Province Portion Of Baja California, Mexico, Bart C. O'Brien, Jon P. Rebman, José Delgadillo-Rodríguez, Kanchi Natarajan Gandhi, Steven A. Junak, Thomas A. Oberbauer, Hugo Riemann, Sula E. Vanderplank
Aliso: A Journal of Systematic and Floristic Botany
The California Floristic Province (CFP) is one of the world’s biodiversity hotspots, known for high levels of plant endemism. The CFP extends from southwestern Oregon, through cismontane California, south to northwestern Baja California, Mexico. The flora of the California Floristic Province portion of Baja California (CFP Baja) has historically been poorly documented and understood. This study provides data to address this deficiency by inventorying and assessing the native flora of CFP Baja from a conservation perspective: evaluating the rarity, endangerment and endemism of its native taxa. A total of 2392 taxa were assessed to determine this listing of rare, endangered …
A Flora Of Coyote Ridge And Flat, Inyo County, California, Martin D. Purdy
A Flora Of Coyote Ridge And Flat, Inyo County, California, Martin D. Purdy
Aliso: A Journal of Systematic and Floristic Botany
California’s Sierra Nevada contains a disproportionate share of the state’s plant diversity and is one of the most floristically diverse regions of its size in the United States. The high Sierra Nevada, in particular, has been identified as an important center of species richness and endemism within the State. Anthropogenic climate warming is expected to disproportionately affect mountain ecosystems, and models have predicted habitat contraction and extirpation for many alpine plant taxa. A specimen-based inventory of the vascular plants and bryophytes of Coyote Ridge and Flat was conducted to establish baseline data for one such sensitive alpine and subalpine area. …

A Vascular Flora Of The Southern Inyo Mountains, Inyo County, California, Maria J. Jesus
Aliso: A Journal of Systematic and Floristic Botany
The Inyo Mountains in Inyo County, California, are an arid mountain range located between the eastern Sierra Nevada and Death Valley National Park. The study site is ca. 433 km2 (167 sq mi), ranging in elevation from 549 to 2955 m (1800 to 9694 ft), and comprises the southern extent of the Inyo Mountains where the Great Basin Desert and Mojave Desert bioregions meet. This area had been poorly represented by botanical collections despite an abundance of distinctive biogeographic features and high diversity in rare and endemic plant species. The objectives of this study were to complete a specimen-based, …
Phylogenetic Relationships Of A North American Radiation Of Clematis (Ranunculaceae), Jesse Harris, Thomas H. Murphy, Erin A. Manzitto-Tripp, Nicolás Medina, Zach Irick, L. Dwayne Estes, Stacey D. Smith
Phylogenetic Relationships Of A North American Radiation Of Clematis (Ranunculaceae), Jesse Harris, Thomas H. Murphy, Erin A. Manzitto-Tripp, Nicolás Medina, Zach Irick, L. Dwayne Estes, Stacey D. Smith
Aliso: A Journal of Systematic and Floristic Botany
Clematis L. is one of many plant genera that contributes prominently to the species richness and endemism of the southeastern United States. Here we examined phylogenetic relationships among species in Clematis sect. Viorna, commonly known as leatherflowers, which are distributed primarily in the southeastern United States. We used data from restriction site-associated ddRADseq to reconstruct a best estimate phylogeny of this group. Our analyses revealed that the North American members of sect. Viorna form a well-supported clade, and several of the traditionally recognized infrasectional taxa were resolved as monophyletic. Although characters employed in classification including habit and inflorescence position …

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 …
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 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 …
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, …

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 …
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 …

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 …
“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 …
