226 BOTANY. 
broader, subcordate at base, and quite membranaceous—Mount Graham, 
Arizona, at 9,250 feet altitude (423). 
‘‘OxYBAPHUS NYCTAGINEUS, Sweet, var. OBLONGIFOLIUS, Gray.—With 
small flowers and leaves. Nevada.”—Warson. | 
OxyBAPHUs HIRSUTUS, Sweet, var.—Leayes lanceolate-linear; stem 
glabrous or nearly so.—Willow Spring, Arizona, at 7,195 feet (206). 
OXYBAPHUS ANGUSTIFOLIUS, Sweet.—Colorado (810, 811, 814), and 
Nevada and Arizona. 
OxyBapnus coccinevs, Torr.—Erect, glabrous; leaves 2—4’ long, 1-3” 
wide ; inflorescence in a loose, terminal panicle; perianth 3-flowered, tinged 
with purple, pubescent; calyx 6-8” long, pubescent externally; stamens 
5, exserted; fruit with 5 corky wings, somewhat roughened. 
ALLIoNIA INcARNATA, L.—(324), Ash Creek, Arizona. 156 a, collected 
by Loew in Arizona, and having the marginal teeth on the fruit quite gland- 
like, and comparing well with Palmer’s specimen in 1875 from St. George, 
Utah, which I find Mr. Watson marks with a doubt. Besides this, I have 107 
from Covero, New Mexico, in which the leaves are quite oval, obtuse, and 
veiny beneath, and the marginal wings of the fruit developed into strong, 
uncinate, glandular teeth, much larger than the central ones, which they 
conceal. This may be a distinct species. My specimens are quite variable, 
some having 4, 5, and even 6 stamens, either included or exserted. The 
Expedition has it also from Nevada. 
ABRONIA FRAGRANS, Nutt—Colorado (808, 812, 813), and New Mexico 
(127), where, in the evening, it was the most fragrant of flowers. 
Asronia TurBINATA, Torr.—Gila Valley, Arizona (340, 765). 
Aproni VILLosa, Watson (American Naturalist, vii, p. 302).—“Covered 
throughout with a more or less dense villous subglandular spreading 
pubescence ; stems weak and slender; leaves small, 4-1 inch long, oblong 
or ovate, obtuse or acutish, attenuate into the slender petiole; heads 5—10- 
flowered ; involucral scales narrowly lanceolate, long-acuminate, 3-4 lines 
long; flowers pink, the lobes obcordate, with a deep sinus; fruit with a 
firm body, strongly reticulate-pitted, the 3-5 broad wings, consisting of a 
simple lamina, usually truncate above. Nearest to A. umBELLATA.”—(Watson 
in Wheeler’s Preliminary Report, 1874, p. 15.) I have not seen the speci-
