Notes On Native Vascular Plants From Mima Mound-Vernal Pool Terrain And The Importance Of Preserving Coastal Terraces In Orange County, California, Richard E. Riefner Jr., Steve Boyd, Roy J. Shlemon

Aliso: A Journal of Systematic and Floristic Botany

We report the following noteworthy collections of native vascular plants from mima mound fields in coastal Orange County, California: Deschampsia danthonioides, Lepidium strictum, and Sagina saginoides (new county records), Lepidium oblongum var. oblongum (previously excluded from the flora), Deinandra paniculata, Holocarpha virgata subsp. elongata, and Navarretia prostrata (new localities in the county), and Hordeum brachyantherum subsp. californicum (uncommon species of local interest). A herbarium study, preparation of voucher specimens, and a generalized distribution, facultative wetland status, and taxonomic notes, where appropriate, are cited for each taxon. An overview of the mima mound micro-relief associated with coastal …

Vascular Plants Of The Whipple Mountains, Sarah J. De Groot

Aliso: A Journal of Systematic and Floristic Botany

The Sonoran and Mojave deserts meet just north of the Whipple Mountains, which are situated in southeast San Bernardino County, California, along the Colorado River and adjacent to Arizona. Vegetation from the Pleistocene to the present was inferred from previously published packrat midden data and the current floristic composition. Climate data suggest that summer rainfall is a factor underlying the vegetational differences between the western and eastern portions of the Sonoran desert. Plant collections in the area yielded primarily California Sonoran plants, but also several Mojave and Arizona Sonoran plants. A fair number of the Arizona Sonoran plants collected were …
