10. O. LATiFOLiA, HBK., d^ov. Gen., v, 237, PL 467, var. Aeaulescent, a sjjan or 

 more high, from a small scaly bulb which bears numerous subterranean bulbiferoxis

 smoother, less conspicuously veined and more deeply parted than in the figure cited, and 

 the stamens different, but agreeing well with various Mexican specimens referred to O.

 ley, Biol. Centr. Amer., i, 163. Aeaulescent from a scaly bulb, glabrous ; leaves few, 

 about a span high, leaflets 3, open V-shaped, more or less conspicuously calloused in the

 twice as long as the leaves, mostly solitary, umbellately about 6-flowered; pedicels at 

 length an inch long; bracts acutish; sepals with 4-6 narrow callosities, flowers other- 

 wise about as in O. violacea, heterogone; capsule ovoid-oblong, somewhat pubescent,

12. O. DiVERGENs, Beuth., PL Hartweg., 9. O. vesjiertilioms, Gray, PL Fendler., 27. 

 O. violacea. Gray, PL Wright., i, 27, ir, 25. An inch and a half to a span high, glal)rous

 4 deeply obcordate or cuneate-bilobed, without an apical callosity, 10-20 mm. long and 

 about as broad, the sinus extending to the middle, lobes divergent, mostly narrowed up-

 ber, 1883), from Mexico. — PL 11, fig. 11. Similar to O. tetraphglla, Cav., but smaller. A 

 large specimen distributed by the Department of Agriculture without locality or date 

 may possibly be the latter.

 tudinally 8-10-creased and transversely wrinkled, .7 X .9 mm. — Arizona ( Greene, 1880 

 no. 211, Pringle, 1881, 301, Lemmon, 2653) and :N'ew Mexico ( Wright, 909), extending
