Acmispon wrightii. Synonym: Lotus wrightii (Deer Vetch)
Fabaceae (Pea Family)

Foothills, montane. Open woodlands, meadows. Summer.
Narraguinnep Natural Area, August 11, 2005.

This attractive Pea has leaves alternately swirled around the stem with a spray of 3-5 very narrow leaflets. The bright red/orange/yellow flowers arise from the leaf nodes. Stems can be upright or reclining. Look for Lotus wrightii in rocky open areas and in openings in Pine and Oak forests.

"Lotus" is an ancient Greek plant name applied to many plants and was, according to Intermountain Flora, "adapted to this genus by botanists of the Renaissance". According to Michael Charter's California Plant Names, "acmispon" is,

"a name published by C.S. Rafinesque, presumably from the Greek "acme", "a point or edge," and explained by him in his publication in Atlantic Journal 1 (4): 144-145, 1832, as "point hooked" in probable reference to the hook-tipped fruit."

The genus occurs in the Mediterranean area and western North America, and was named by Linnaeus in 1753. In 1853 Asa Gray named the species shown on this web page, Hosackia wrightii, and in 1890 Edward Greene renamed it Lotus wrightii. Charles Wright was a trusted plant collector for John Torrey and Asa Gray. (More biographical information about Wright.)
