List of southern LCRV flora by region

A List of southern Lower Colorado River Valley-(LCRV) flora by region. The regions included are::#southeast Colorado Desert
(borders the Colorado River on east):#Little Picacho Wilderness
"located in the extreme southeast Colorado Desert"
10 miles northeast of Yuma, Arizona, and Winterhaven, California in southeast Imperial County, California.:#Muggins Mountains Wilderness
17 miles northeast of Yuma, Arizona on the southwest of the Muggins Mountains range:#City of Yuma, Arizona

Many parts of the Lower Colorado River Valley, and especially low- or middle-elevation desert regions are: the "Creosote bush scrub" biome. (Some other indicator species of the biome might be considered to be: "Encelia farinosa", "Krameria grayi", Anderson Thornbush, "Bebbia juncea," etc.) In the western Sonoran Desert this may include the Ocotillo and Saguaro; in the Colorado Desert, only the Ocotillo.

Bolded species are the "Creosote bush scrub biome" species-(i.e. the creosote bush: "Larrea tridentata", Saguaro, Ocotillo), or the endemics, or "near-endemics" to the LCRV region-(endemics listed in final section).
