 flowers few, in a subcapitate at length elongated raceme; calyx obconieal, 

 with triangular acute lobes ; petals white or pinkish, deeply 3-cleft into 

 linear or oblong lobes, attenuate below to a slender claw, 4-6 lines long, 

 capsule oblong, often 3-va ved, open only at the top. Common in moist 

 or shady places, Brit. Columbia to California and Colorado. 



L. tenella Nutt. T. & G Fl.i, 5U Tellima, tenella Walp. Roughish 

 with a minute glandular pubescence: stems slender, branching from the 

 base, 4-12 inches high : leaves trifoliolate; leaflets 2-3-parted, with cunei-

 length from the top: seeds short-oblong, rough-tuberculate. Common on 

 prairies, Brit. Columbia to California and Colorado. 



L. rnpicola Greene Eryth. iii, 102. '-Stems often 2 or 3 from the small 

 grumous root, not very slemder, a foot high or more, rather strongly hispi- 

 dulous-scabrous throughout: lowest leaves from round-reniform to round- 

 ovate in outline, deeply 3-5-lobed, the lobes again 3-lobed; petioles long, 

 each with a large b'llblet in its axil ; cauline leaves of more angular outline, 

 doubly cleft into narrow segments: racemes elongated, l2-20-flowered; 

 fruiting pedicels nearly twice the length of the calyx: hemispherical base 

 of the calyx adherent to the ovary, the body in maturity obviously 10-stri- 

 ate, the lobes short and obtuse; petals white, all deeply palmatifid, the 2 

 upper much smaller than the others : capsule 3-valved at the apex and the 

 valves well exserted: seeds striate lengthwise but neither muriate nor 

 obviously granular. Lava beds of Modoc Co., California, growing in the 

 shade of Junipers." Perhaps in adjacent Oregon.

 Perennial herbs with mostly radical leaves, slender stems and

 campanulate, more or less coherent with the ovary. Petals 5,

 ous. Stamens 5 or 10, not exserted ; anthers cordate or reni- 

 form, 2-pelled. Styles 2, short and distinct. Capsule 1 -celled, 

 with 2 parietal or somewhat basal many-seeded placentee, 2- 

 valved at the summit. Seeds obovoid, horizontal or ascending,
