 Roughish hirsute or scabrous-pubescent: stems slender, 8-20 inches high: 

 radical leaves roun<l -cordate, deeply 3-5-lobed, the lobes coarsely toothed ? 

 6-10 lines in diameter, on slender "petioles 1-4 inches long; cauline leaves 

 usually 2, trifoliolate, leaflets deeply 3-lobed, the lobes 2-3-toothed; 

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

 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, 5S4 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- 

 form 2-3-lobed segments: flowers few, in a capitate at length elongated 

 often bulblet bearing usually simple raceme; calyx campanulate, 2 lines 

 long, with very short triangular teeth ; petals pink, 6 lines long, irregu- 

 larly 3-7-parted into mostly linear-lanceolate, acute divisions: capsule 

 almost free from the calyx, elliptical, usually 3-valved opening % its 

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

 prairies, Brit. Columbia to California and Colorado. 



L. rupicola Greene Eryth. iii, 102. " Stems often 2 or 3 from the small 

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

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

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

 each with a large bulblet in its axil; cauline leaves of more angular outline, 

 doubly cleft into narrow segments: racemes elongated, 12-20-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. 



12 MITELL i. L. Gen. n. 561. 



Perennial herbs with mostly radical leaves,. slender stems and 

 small flowers in simple spicate raceme*. Calyx 5-cleft, short- 

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

 lobed or pinnatifid, inserted into the throat of the calyx, decidu- 

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

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

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

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

 smooth and shining.
