BigELovia Parryi, Gray.—Woody at base, 1° high, at first softly 
tomentose, at length nearly glabrous; leaves linear, 2-3’ long, 2” wide; 
heads in a narrow thyrse, rather large; scales of the involucre loosely im- 
bricated in about 3 series, acutish, or with the tips sometimes attenuated, about 
12-flowered; teeth of the corolla rather large, tube puberulent; appendages 
of the style subulate or filiform—Twin Lakes, Colorado, at 9,800 feet 
(453). (Linosyris Parryi, Gray, in Proc. Acad. Phila. 1863, p. 66.) 
BicgeLovia BicELovil, Gray.—Woody at and a little above the base, 
much branched from below; whole plant somewhat ash-colored; leaves 
filiform, revolute, more or less recurved and scattering; heads 4—6-flowered, 
in a raceme or slender panicle; scales of the involucre coriaceous, lanceolate, 
often acute or acuminate and in 4 or 5 series; pappus quite tawny, as long 
as the very slender flower; achenia smooth, linear, 4—6-angled, and with 
a broad epigynous disk; appendages of the style long and filiform, a little 
roughish under the lens——Headwaters of the Arkansas in Colorado (454). 
BIGELOVIA GRAVEOLENS, Gray. (Linosyris graveolens and albicaulis, 'T. 
& G. Fl. 2, p. 234.)\—Colorado, New Mexico, Arizona, Nevada, and Utah; 
also var. albicaulis, Gray, obtained from Nevada. 
BigeLovia Dovexasu, Gray (Linosyris viscidiflora, T. & G.), var. SER- 
RULATA, Gray; also var. TorTIFoLIA, Gray.—T'win Lakes, Colorado (413, 
447). (478 is a broad-leaved form.) 7 
Sotmaco Catrrornica, Nutt., var.?—Stem simple, whole plant more or 
less densely covered witha short pubescence; leaves thickish, entire, oblong, 
1-3’ long and 2-9” wide; heads crowded into a dense, contracted panicle; 
scales of the involucre thickish, obtuse, and the outer puberulent; rays 6-8 
(less numerous than the disk-flowers), large (2-3” long); achenia pubescent. 
This form (730) from Mount Graham, Arizona, and at an altitude of 
9,000 feet, may prove a distinct species; believing, however, that its nearest 
affinity is as above indicated, I place it here for the present. 
Sotipaco Virea-aurEA, Linn., var. HuMILIs, Gray.—(86 of Loew); 
(409, 404), from Colorado, and a specimen without number, collected by 
Loew from Mogollon Mesa in Arizona, 4,000 to 5,000 feet. Var. aLrina, 
Bigel. (407), Half-Moon Creek, Colorado, at 12,000 feet altitude.
