A Revision Of Erythranthe Montioides And Erythranthe Palmeri (Phrymaceae), With Descriptions Of Five New Species From California And Nevada, Usa, Naomi S. Fraga
A Revision Of Erythranthe Montioides And Erythranthe Palmeri (Phrymaceae), With Descriptions Of Five New Species From California And Nevada, Usa, Naomi S. Fraga
Aliso: A Journal of Systematic and Floristic Botany
The genus Erythranthe (Phrymaceae) continues to be a source of floristic novelty, especially in the American West, as evidenced by recent discoveries presented here. Two species in Erythranthe section Paradantha (E. montioides and E. palmeri) have long been a source of taxonomic confusion. Recent research reveals that a total of ten species have previously been treated as part of these two species. Here I present a revised taxonomy for E. montioides and E. palmeri including clarification of species circumscriptions (E. montioides, E. palmeri), recognition of three species that have previously been treated as synonyms …
The Flora Of Greater San Quintín, Baja California, Mexico (2005–2010), Sula E. Vanderplank
The Flora Of Greater San Quintín, Baja California, Mexico (2005–2010), Sula E. Vanderplank
Aliso: A Journal of Systematic and Floristic Botany
The plants of San Quintín (Baja California, Mexico) were documented through intensive fieldwork and collection of herbarium specimens to create a checklist of species. The region is located near the southernmost extent of the California Floristic Province, and the flora is influenced by the adjacent desert to the south. A total of 435 plant taxa were documented, of which 82% are native plants. Almost one in three native plant taxa in Greater San Quintín is a sensitive species, here documented as rare and/or locally endemic, and many taxa have yet to be evaluated fully for rarity and threats. Four major …

Aliso: A Journal of Systematic and Floristic Botany
The Colonet region is located at the southern end of the California Floristic Province, in an area known to have the highest plant diversity in Baja California. A preliminary list of vouchered specimens is developed for the area, and a vegetation map for Colonet Mesa is presented. The Colonet region has at least 435 vascular plant taxa, of which 383 are native to Baja California, and 52 are endemic or nearly endemic. This list includes five local endemic taxa known only from the Colonet region, 18 taxa on the California Native Plant Society List 1B of taxa that are "rare, …
Descriptive Anatomy And Evolutionary Patterns Of Anatomical Diversification In Adenia (Passifloraceae), David J. Hearn
Descriptive Anatomy And Evolutionary Patterns Of Anatomical Diversification In Adenia (Passifloraceae), David J. Hearn
Aliso: A Journal of Systematic and Floristic Botany
To understand evolutionary patterns and processes that account for anatomical diversity in relation to ecology and life form diversity, anatomy of storage roots and stems of the genus Adenia (Passifloraceae) were analyzed using an explicit phylogenetic context. Over 65,000 measurements are reported for 47 quantitative and qualitative traits from 58 species in the genus. Vestiges of lianous ancestry were apparent throughout the group, as treelets and lianous taxa alike share relatively short, often wide, vessel elements with simple, transverse perforation plates, and alternate lateral wall pitting; fibriform vessel elements, tracheids associated with vessels, and libriform fibers as additional tracheary elements; …

An overview of the mima mound micro-relief associated with coastal …
Shifting Paradigms In Island Biology, Sherwin Carlquist
Shifting Paradigms In Island Biology, Sherwin Carlquist
Aliso: A Journal of Systematic and Floristic Botany
The ease of travel by jet aircraft has opened up island areas not only for study but also for introduction of weeds, pests, and pathogens. We are at a critical juncture in the study of island organisms, which have become more accessible at the same time that they are vanishing. With the urgency for study of island organisms, we have many new tools, especially molecular ones, which have validated the existence of long-distance dispersal in unexpected ways. These tools, together with the ease of staying for longer periods on islands, have permitted us to understand many aspects of evolutionary adaptation …
Plant Conservation In The Juan Fernandez Archipelago, Chile, Tod F. Stuessy, Ulf Swenson, Daniel J. Crawford, Gregory Anderson, Mario Silva O.
Plant Conservation In The Juan Fernandez Archipelago, Chile, Tod F. Stuessy, Ulf Swenson, Daniel J. Crawford, Gregory Anderson, Mario Silva O.
Aliso: A Journal of Systematic and Floristic Botany
Oceanic archipelagos often hold very specialized floras with high degrees of endemism. These floras are frequently highly vulnerable to disturbance by natural causes and human intervention. The Juan Fernandez Islands (Chile) in the Pacific Ocean are a small archipelago of only three islands. Since discovery in 1574 by Juan Fernandez, human activities have altered floristic composition and survival circumstances of the endemic species. In this paper we document past and present means of disturbance, both anthropogenic and natural, which have influenced the native vegetation. The most destructive past activities have been logging and .introduction of animals and plants, both deliberately …
Conserving Plants As Evolutionary Entities: Successes And Unanswered Questions From New Zealand And Elsewhere, Ian A. E. Atkinson
Conserving Plants As Evolutionary Entities: Successes And Unanswered Questions From New Zealand And Elsewhere, Ian A. E. Atkinson
Aliso: A Journal of Systematic and Floristic Botany
Saving a species from extinction may not insure that its future will continue as before, even when the surviving population is in a wild habitat. Former selection forces may be missing or replaced by others so that the species develops along a different evolutionary pathway. Such disruption of evolutionary direction may be particularly important for island taxa given that modification by humans and their introduced organisms is making many islands more similar to continental habitats. In restoring habitats for island species, special attention should therefore be given to identify ing the major selective forces likely to have been operating during …
Population Structuring And Patterns Of Morphological Variation In Californian Styrax (Styracaceae), Peter Fritsch
Population Structuring And Patterns Of Morphological Variation In Californian Styrax (Styracaceae), Peter Fritsch
Aliso: A Journal of Systematic and Floristic Botany
Recent studies of genetic variation within and among populations and phylogenetic estimates have provided evidence bearing on the evolutionary history and taxonomy of Styrax in California (S. redivivus). In this paper, data from these studies are further analyzed and integrated with new data from morphology to gain insight into the nature and taxonomic significance of character variation within this species. Six morphological characters thought to be important in the delimitation of infraspecific taxa within S. redivivus were measured on 52 herbarium specimens and analyzed with Pearson correlations and multivariate methods. Five characters are significantly associated with latitude and …

In The Beginning, Lee W. Lenz
In The Beginning, Lee W. Lenz
Aliso: A Journal of Systematic and Floristic Botany
This article traces the early history of Rancho Santa Ana Botanic Garden, California, starting ca. 1867 with the Portolà Expedition. The expedition was the first to record the site where the botanic garden later came to be located, in Santa Ana Canyon, northeastern Orange County. Successive changes in land ownership eventually led to the Bixby family purchasing the land in 1875. Susanna Bixby Bryant, the founder of Rancho Santa Ana Botanic Garden, acquired the land in 1925.

The Botanic Garden Moves, Lee W. Lenz
Aliso: A Journal of Systematic and Floristic Botany
In 1950, the decision was taken to relocate Rancho Santa Ana Botanic Garden from its original site—Mrs. Susanna Bixby Bryant's ranch in Santa Ana Canyon, northeastern Orange County—to today's Claremont location in eastern Los Angeles County. The move reflected a wish to align the founder's mandate to "foster scientific research and public welfare" by seeking affiliation with the Claremont Colleges. The change enabled it to train graduate students in botany and related fields and draw more visitors to a garden devoted to native California plants. Accounts describe how the new site was adapted to its purpose, including the construction of …
