Working on plants in the Little Picacho Wilderness–(extreme southeast Colorado Desert//southeastern California-bordering the Colorado River/Imperial Dam water to the Salton Sea, Imperial Valley farmlands). For the Little Picacho Wilderness flora, I made my second hike on March 28, 2008, ....and made a point to get to one of the peaks, in the south center of the Wilderness. It is on a volcanic extensive "ridgeline–mountaintop", composed of jumbled volcanic rocks, interspersed with some soil-(regolith). The central peak is a ridgeline probably about 0.7 miles (1 km) in length, with a side spur. I accessed a western ridgeline to the separate southern peak, (avoided it), then went from the intermediate ridgeline saddle to the center peak area. The following species were on the mountaintop: ---the Ferocactus wislizeni became more numerous, nearer the mountaintop-(especially the saddle area//hillsides there)-at about 1,500 feet (457 m), and is profuse on the steep hillsides. (It occurs on the flatlands below, but is a very sparse plant there.)-(At the Saddle regions, the Barrel Cacti are interspersed with a forest of Ocotillo and Encelia farinosa-(also some desiccated Beavertail Cactus on the access ridgeline)) ---Encelia farinosa and Creosote bush ---Bursage and "Saltbush"-(Saltbush: not seen commonly-(but was on the peak!)) ---Rigid Spiny Herb-(near peak) and Mentzelia involucrata-(both found at all elevations) ---Lycium andersonii ---Desert Globemallow ---Psyllium ssp ---Desert Tobacco, the Nicotiana obtusifolia ---Cryptantha angustifolia ssp ---California Fagonbush, (the Fagonia laevis)-(common everywhere, especially amongst rocks-(all elevations)) ---and a "Trailing Four-o'clock species"-(also at all elevations)..(a SonoranDesert-fellow-)Mmcannis (talk) 08:59, 29 March 2008 (UTC)[reply]
