 Hartw, 306 (1849). Lotus hrcichyccirpus^ "Wats. Index, 225 

 (1878), not of Hochsi (1842).— Middle and southern Cali- 

 fornia and in southern Arizona; near the preceding and 

 sometimes confounded with it, but readily distinguished by 

 its prostrate habit, soft pubescence, subsessile flowers, calyx- 

 teeth much longer than the tube, and very short 2- or 3-seeded 

 pod. 



5. L. DENTicuLATUS. Hosaclda denficulaia, Drew, Bull. 

 Torr. Club. xvi. 151 (1889). Erect, 1 to 2^ feet high, 

 branching somewhat fastigiately, pale green and glaucous, 

 sparingly pilose : calyx-teeth longer than the tube, denticu- 

 late; corolla only 2 lines long, pale yellow or salmon-color, 

 chauging to a rich dark red : pod pubescent, very short, 

 3-seeded. — An excellent species, long confounded with L. 

 W)xmgeUcmus. It combines the characteristics of two groups 

 of species, the preceding, in which the flowers are solitary, 

 short-peduncled and bractless, and the following, in which 

 they are several, in a bracted umbel, at the end of a long 

 peduncle ; for most of the upper axils of L, denficulalus may 

 be observed to yield two peduncles, one of which is very short 

 and 1-flowered, the other greatly elongated, bracted and often 

 2-flowered. The species is common from Butte and Humboldt 

 counties io California, northward to Vancouver Island. It
