 Dr. Kellogg read the following descriptions of new plants : 



Allium anceps (Kellogg). — Bulb broadly ovate, half to one 

 inch in diameter. 



Scape short, (four to six inches, or about half the length of 

 the leaves) naked, ancipital, somewhat attenuate below, trans- 

 lucent margins scabrulose (often horizontally cleft by the thin 

 edges contracting in arid states of the atmosphere as it ap- 

 proaches maturity). 



Leaves two radical, plain, somewhat ancipital nearly the 

 whole length or very slightly convex beneath at the attenuated 

 base, which is not sheathing, striate, margins scabrous, lamina 

 tortuously undulate, sometimes falciform, about twice the length 

 of the scape, apex subacute. 



Spathe two-leaved, equal ovate, acute, seven to nine-nerved, 

 membranaceous, persistent, base connate. 



Heads in general outline obconic convex, twenty to thirty- 

 flowered ; in this specimen the umbel is loose ; seven to nine- 

 flowered, on slender, glabrous, slightly compressed pedicels, 

 subturbinately enlarged at the base of the perianth, half to 

 three-quarters of an inch in length (twelve or more rudimenta- 

 ry pedicels occupying the center of the umbel. 



Perianth pale pinkish, segments linear-lanceolate acute, cari- 

 nate, margins scariose, a difi'use green line along the center, 

 most conspicuous on the back of the three exterior divisions, 

 curved spreading (base connate.) 



Stamens subequal (the three exterior at first shorter, at length 

 equal ; nearly as long as the segments). 



Filaments subulate, base extended, attenuate above, the up- 

 per third bright lilac, anthers verditer blue. * 



Style about half the length of the stamens, simple (sharply 

 pointed stigma, scarcely three-lobed under a strong glass). 



Fruit capsular, obovate, three-celled, each cell two-seeded, 

 seeds compressed ; cells minutely six-toothed, crested. 



A Washoe species collected by Andrew A. Veatch and culti- 

 vated by Mr. H. G. Bloomer, Botanical Curator to the Acade- 

 my. We have also specimens from Onion Valley.
