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 calyx ; the 4 lobes very short : style at length much 

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



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

 woolly: leaves linear-spatulate, 6 to 12 hues 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. 68, the corolla badly 

 drawn and unlike the description. — N. W. Mexico (Seemann) and Magdalena, Sonora, Thur- 

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

 L. BREVIPE8, Benth., and L. Richii, Gray, are little known species of Lower California. 

 •>—■•—. -1— -»— 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. ' 



++ 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-funnel- 

 form, 4 to 6 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- 

 mont. Arizona, Palmer. 



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

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



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 with 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. 



++ ++ 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 branches : 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. slolidum & L. senticosum, Miers, 1. c. 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 Hues wide; its rounded lobes with nearly glabrous edges: filaments slightl}' 

 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. W^rightii, 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. Berlandieri, Gray, Proc. Am. Acad. vi. 47, in small part. — S. Arizona, Wright, 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- 

 node, Torr. in Pacif . R. Rep. v. 363, & Bot. Mex. Bound. 154. — Western border of Texas,
