1. Scape stout and tall, terete, from a small ovate coated corm and propa- 

 gating by a lateral bulb-bearing offshoot: leaves linear: capsule not 

 crested. 



1. A. unifolium, Kell. Bulb deep-seated, 6 to 8 lines long, with a white 

 somewhat charfcaceous coat, marked by a close contorted reticulation, separated from 

 the younger bulb above by a rooting rhizome \ to 1 inch long : leaves 2 to 4, sheath- 

 ing below the ground, flat or somewhat carinate, 1 to 4 lines broad, shorter than the 

 scape, which is a foot or two high : bracts 2, large, acuminate : pedicels 10 to 30, 

 usually 1| inches long : flowers bright rose-color fading to white, the broadly oblong- 

 lanceolate acute or somewhat acuminate segments 5 to 7 lines long, a third longer 

 than the stamens and style. Proc. Calif. Acad. ii. 1 1 2, tig. 35 ; Watson, Bot.
