8. C. BigELovu, Torrey.—“‘ Low (7), herbaceous (?),” (in reality as 
seen in later specimens climbing), smooth; leaves pinnate or bi-pinnate, 
long petioled, leaflets 7-9, half an inch to an inch in length, membran- 
aceous and inconspicuously veined, 3-lobed or parted: lobes sub-ovate, 
entire, or incised, peduncles “an inch or two in length’’ (sometimes 
four and five inches), one flowered, nodding; calyx sub-campanulate, 
sepals narrowly oblong, scarcely over half an inch in length, membran- 
aceous in dried state, probably a little thickened in the living plant, 
but not leathery as in C. Viorna, etc.; almost glabrous except the 
densely tomentose margin, not appendaged, but the obtuse tip spread- 
ing; carpels silky pubescent, becoming glabrate, with tails over an 
inch in length, densely plumose as in C. Viorna.* 
9. C. RETICULATA, Walt.—Stems climbing, leaves pinnate or ternate; 
leaflets 3-6, oblong, ovate or oval, entire, simple or lobed, obtuse or acute 
and mucronate, rigidly coriaceous, conspicuously reticulated on both 
sides, glabrous: peduncle terminal, one flowered, flower nodding, bell- 
shaped, pale purple; sepals 1’-13’ long, rather coriaceous, ovate lanceo- 
late, velvety externally: tails of the carpels long and plumose.t 
‘10. C. crispa, Linn.—Stem smooth, climbing; leaves pinnate or 
ternate; leaflets 3-15, acute, thin, varying from oblong-ovate to lanceo- 
late, acuminate, obtuse or sub-cordate at base, entire or 3-5 parted; 
peduncle terminal, bearing a large, nodding, bell-shaped, bluish-purple 
flower; calyx cylindraceous below, the upper half of the sepals dilated 
and widely spreading, with broad and wavy thin margins; tails of the 
carpels about an inch long, silky or plumose (in the form originally 
described with “ naked” or pubescent tails).{ 
Var. Watteri, Gray (C. Walteri, Pursh., C. lineariloba, DC.) 
Leaflets linear or linear lanceolate, 3-4 pairs, the lobes scarcely 2’’-3” 
wide.§ 
11. C. rastantHa, Nutt.—Stem pubescent, or silky tomentose, stout, 
climbing; leaves ternate, broadly ovate, obtusely cuneiform at base; 
leaflets incisely toothed, the terminal one three lobed or trifid, 1’-14 
long, 1’ broad, almost villous beneath ; flowers dicecious, solitary, more 
than an inch in diameter, on rather stout 1-2 bracted peduncles 3 
inches long; sepals cuneate oblong, spreading, villous on both surfaces, 
obtuse, 6’’-10” long, akenes pubescent. |
