L. parviflorum, Gray. Stems 2 to 4 feet high : leaves 2 to 5 lines long, narrow, not 

 fleshy : corolla (2 lines long) funnelform, rather more than twice the length of the short- 

 campanulate often irregularly 2-3-clef t ealyx ; the 4 lobes very short : style at length much 

 exserted. Proc. Am. Acad. vi. 48. Southern Arizona, Thurber. 



L. barbinodum, Miers. Stouter, 6-10 feet high; the old spurs or nodes densely short- 

 woolly: leaves linear-spatulate, 6 to 12 lines long: corolla (2 lines long) with narrow 

 tube about equalling the commonly 2-3-cleft short calyx, abruptly enlarged into a broadly 

 campanulate throat; the lobes 5, short, roundish. 111. 1. c. 115, t. 08, the corolla badly 

 drawn and unlike the description. N. W. Mexico (Seemann) and Magdalena, Sonora, T/tur- 

 ber (who says the berries are white and translucent) ; doubtless in adjacent Arizona. 

 L. BREVIPES, Benth., and L. RICHII, Gray, are little known species of Lower California. 



i 4 -i -) Long-flowered; the corolla tubular or when funnelform with tube and throat over 

 two lines long and much exceeding the lobes, white, cream-color, or tinged with, violet: stamens 

 little if at all exserted. 



H- Leaves, pedicels, and calyx puberulent: flowers 5-merous. 



L. Fremonti, Gray. Stem 2 to 4 feet high: leaves spatulate, 4 to 9 lines long : pedicels 

 shorter than or barely equalling the cylindraceous calyx: corolla narrowly tubular-funuel- 

 form, 4 to C lines long, with very short ovate lobes : filaments nearly naked : style soon 

 exserted. Proc. Am. Acad. vi. 46, & Bot. Calif, i. 543. S. E. California or Nevada, Fre-

Var. Bigelovii, Gray, 1. c. Calyx shorter-campanulate : corolla broader and merely 

 4 lines long : filaments slightly hairy at base. Williams Fork, N. Arizona, Biyelow. 

 L. gracilipes, Gray. Minute pubescence somewhat viscid or glandular : leaves small 

 (2 to 6 lines long), spatulate or the smaller oblong-obovate, thickish : pedicels filiform, as 

 long as the flower : calyx campanulate, short-toothed : corolla elongated-f unnelform, half 

 inch long, white witli a violet tinge or sometimes deep violet ; the lobes rounded-ovate, 

 very obtuse, a line long : filaments inserted low in the throat, a little hairy at base : anthers 

 and style not exceeding the corolla-lobes. Proc. Am. Acad. xii. 81. Williams Fork, N. 

 Arizona, Palmer. 



-H- -H- Glabrous throughout, or merely some woolly pubescence on the spurs at the insertion of the 

 leaves and pedicels : flowers in the same species either 5-merous or 4-merous. 



= Pedicels filiform, as long as the commonly 4-merous rather short funnelform corolla. 



L. Berlandieri, Dunal. Spiny, 3 to 8 feet high, with mostly slender brandies : leaves 

 spatulate-linear, 6 to 12 lines long : corolla 3 or 4 lines long, mostly thrice the length 

 of the campanulate calyx which nearly includes its narrow proper tube ; the lobes oval or 

 oblong (a line long) : filaments villous at base. DC. Prodr. xiii. 520; Gray, Proc. Am. 

 Acad. vi. 47. L. stolidum & L. senticostun, Miers, I.e. t. 68, 71. S. Texas, Berlandier, 

 Wright, to Arizona, Palmer. 

 = = Pedicels (1 to 3 lines long) shorter than the tubular-funnelform corolla: flowers copious. 



L. Andersonii, Gray. Exceedingly branched, 2 or 3 feet high : leaves mostly very 

 small (2 to 6 lines long), linear-spatulate or broader: calyx short-campanulate : corolla 

 half inch long or nearly, tubular, very gradually widening upward ; the expanded limb 

 only 2 or 3 lines wide ; its rounded lobes with nearly glabrous edges : filaments slightly 

 hairy at base : berries bright red, "edible." Proc. Am. Acad. vii. 388, & Bot. Calif. 1. c. 

 Utah, S. Nevada, and N. Arizona, first collected by Anderson. 



Var. "Wrightii, Gray. More leafy and sparsely flowered, spiny, smaller-flowered : 

 corolla 4 or 5 lines long. Bot. Calif. 1. c. L. stolidum, Torr. Bot. Mex. Bound., in part. 

 L. Berlandier!, Gray, Proc. Am. Acad. vi. 47, in small part. S. Arizona, Wriyht, Palmer. 



L. Torreyi, Gray, 1. c. More or less spiny, 4 to 8 feet high : leaves mostly larger than 

 in the preceding, sometimes over an inch long and over 2 lines wide : pedicels 2 or 3 lines 

 long : corolla 5 or 6 lines long, more funnelform ; the limb about 4 lines wide, and the lobes 

 tomentulose on the edges : filaments woolly at base : berries red, " not edible." L. barbi-
