NOVITATES OCCIDENTALES.— VI. 
By Epwarp L. GREENE. 
Lotus confinis. Perennial; stems tufted, decumbent, 
barely a foot,long; herbage velvety-pubescent: leaflets 5 to 4, 
obovate, acutish, 6 or 8 lines long; internodes about equalling 
the leaves; peduncles twice as long, bearing an unifoliate- 
bracted umbel of 3 to 7 large flowers: calyx-teeth subulate 
from a broad base, half as long as the campanulate tube: 
corolla 9 or 10 lines long, of a rich red-purple; petals not 
very unequal: legume unknown. 
Near L. grandiflorus and leucopheus; distinguished from 
the latter by the relatively much shorter and broader calyx- 
teeth, and the larger corolla, the petals of which are always 
deep red,.even in the bud. Species obtained by Mr. R. D. 
Alderson in the mountains of San Diego Co., Calif., near the 
United States and Mexican boundary, 1893. 
Lotus trispermus. Near L. humistratus, rather smaller, 
decidedly less conspicuously villous: calyx-lobes subulate 
rather than linear, hardly longer than the tube: pods linear- 
oblong, 3-seeded: seeds obscurely quadrangular, thick in the 
middle, thin and acute at the edges but not at the ends. 
Common on hills bordering the Mohave Desert, Calif., 
thence eastward and southeastward in Arizona. Species long 
confused with L. humistratus but clearly distinct by good 
character of the calyx and seed. Good specimens sent from 
near Lancaster, Calif, by Dr. Anstruther Davidson, have
