Distribution And Regional Ecology Of Californian Palm Oases Interpreted From Google Earth Images, Richard A. Minnich, Ernesto Franco-Vizcaíno, Mario Salazar-Ceseña
Distribution And Regional Ecology Of Californian Palm Oases Interpreted From Google Earth Images, Richard A. Minnich, Ernesto Franco-Vizcaíno, Mario Salazar-Ceseña
Aliso: A Journal of Systematic and Floristic Botany
The native fan palms of the Baja California peninsula (Mexico) and neighboring southern California (USA) comprise two species each in Washingtonia and Brahea. While these are among the most familiar ornamental palms in the world, many features of their taxonomy, distribution, and environmental relationships remain unresolved. We utilized Google Earth Digital Globe imagery (and limited surveys by air and land) to develop the first map detailing the geographic distribution of palm populations in the Peninsular Range Province (PRP) and used these data to formulate new hypotheses on their biotic and abiotic relationships. We inventoried 15,216 populations covering an area …
A Phylogenetic Study Of Arecaceae Based On Seedling Morphological And Anatomical Data, Flor M. Henderson, Dennis W. Stevenson
A Phylogenetic Study Of Arecaceae Based On Seedling Morphological And Anatomical Data, Flor M. Henderson, Dennis W. Stevenson
Aliso: A Journal of Systematic and Floristic Botany
A morphological and anatomical survey was carried out of seedlings of 62 taxa of palms representing all major groups. The data were analyzed using cladistic parsimony analysis. Seedling data were analyzed independently and combined with adult morphological data. Outgroup selection was made within the family using the calamoids and Nypa fruticans; outside the family, the monocot family Dasypogonaceae were used. The analysis with the calamoids and Nypa fruticans as outgroups resolved some of the major groups. The combined analysis, using both seedling and adult data and Dasypogonaceae as the outgroup, provided better resolution. Most of the major groups were …
The Palms (Arecaceae) Of Sonora, Mexico, Richard S. Felger, Elaine Joyal
The Palms (Arecaceae) Of Sonora, Mexico, Richard S. Felger, Elaine Joyal
Aliso: A Journal of Systematic and Floristic Botany
This publication is an account of the palms (Arecaceae) in the state of Sonora in northwestern Mexico. Six native palm species in three genera are recorded for Sonora: Brahea with four species, and Sabal and Washingtonia each with one species. Relationships and taxonomy within Brahea, especially B. elegans, remain unresolved. Brief botanical descriptions, taxonomic synopses, local names, identification keys, conservation status and recommendations, and distributional and ethno- botanical information are provided for each species. Basionyms and types are cited. Distributions are documented with citations of nearly all herbarium specimens known to us from Sonora. Many palm populations in …
A Monograph Of Sabal (Arecaceae: Coryphoideae), Scott Zona
A Monograph Of Sabal (Arecaceae: Coryphoideae), Scott Zona
Aliso: A Journal of Systematic and Floristic Botany
This monographic study of the New World genus Sabal (Arecaceae: Coryphoideae) recognizes 15 species. In addition to defining species limits and distributions, the study addresses broader questions concerning likely modes of speciation in the group and biogeographic radiation. The systematic treatment incorporates results from extensive field work and studies of leaf anatomy and flavonoid phytochemistry, ecology and biogeography, and morphology. Distribution maps and a key to the taxa are provided. Solutions are offered for the many nomenclatural problems that existed in the genus. A phylogenetic hypothesis, the first for the genus, is proposed. Moreover, phytochemical and anatomical features are examined …
