Trees and Shrubs of Kern County (Jan 2013)

     Acmispon. Herbs, subshrubs or shrubs; leaves alternate, ± pinnately divided into (2-) 3–5 (-7) leaflets, with odd terminal leaflets and sometimes with an odd number, 3, alternate lateral leaflets; flowers often many in umbellate clusters on short to long or obsolete solitary scapes (peduncles) arising from leaf axils, or sometimes few or one, usually yellow; fruit dehiscent or indehiscent, usually terminating in a slender curved beak. Previously included in Lotus, which differs by lower pair of leaflets crowding the stems (“stipular position”) and distantly spaced from upper leaflets, and from Hosackia, which has evenly spaced opposite leaflets. ±23 species in western North America and 1 in Chile; 22 in California, 1subshrub species in Kern County.

Acmispon glaber (Syrmatium glabrum Vogel 1836) Brouillet 2008 var. glaber California broom, deer weed. [Lotus scoparius (Hosackia scoparia Nuttall 1838) Ottley 1923]. Subshrub with numerous broom-like erect branching stems up to 2 m; leaves divided into 3 leaflets on upper stems, or to 6  leaflets on older stems; flowers Mar–Aug, yellow aging reddish orange, in small verticillate-like clusters of 2–7 in leaf axils along green stems, 2–7 mm; fruit cyclindrical, reflexed or spreading, with upcurved beak, 10–15 mm. Coast Ranges as far north as near Fortuna, CA, Sierra foothill woodland, and western Sonoran Desert, south to Sierra Juárez in Baja  California. Deer weed scrub recognized in MCV2 when >50% relative cover in the shrub canopy. Type from California. Kern Co.: Common along Hwy 178 in Kern Canyon. A. glaber var. brevialatus (Ottley) Brouillet, which is generally scarce in Kern County—according to Twisselmann—is recognized by a more prominent keel exceeding the wings of the flower that is 7–12 mm long, whereas flowers in var. brevialatus are within the range of variation, 8–9 mm long.

Res. 20: 922–926.  “Investigation of the roots of Lotus polyphyllos Clarke resulted in the isolation of two new isoflavone derivatives; 4'-O-methylerythrinin C (3) and 4'-O-methyl-2''-hydroxydihydroalpinumisoflavone (4). In addition, the three known isoflavone derivatives 4'-O-methylalpinumisoflavone (1) lupinalbin F (5), 4',7-dimethoxy-5-hydroxyisoflavone (6), and the phenylpropanoid ester tetracosyl p-coumarate (2) were also identified. The structures were determined from spectroscopic data.”

Chem., 25: 107–112.  “The methanol soluble part of Lotus garcinii, belonging to the family Fabaceae, yielded three new interesting metabolites: garceine (1), garoside (2) and garthiol (3), which have never been detected from any natural source. In addition, isophytol, hexadecanoic acid, cholesterol, oleanolic acid, butulinic acid and lupeol were also obtained for the first time from L. garcinii. All the isolated metabolites were characterized by spectroscopic means.”
