144. BOTANY. 
leaves linear-lanceolate or lanceolate, tapering (usually) into long petioles, 
entire or irregularly and sharply serrulate, acute; upper leaves few, 
smaller and sessile; heads large, generally solitary; involucre mostly woolly 
(sometimes becoming glabrous when old); scales in about three series, | 
lanceolate and rather obtuse; rays many and very variable in size and 
shape (in most of my specimens the rays are sterile); disk-flowers 2” long; 
achenia fusiform, villous; pappus light brown.—Union Creek Pass, Colo- 
rado, at 10,000 to 11,000 feet (472, 579). 
APLOPAPPUS LaRICIFOLIUS, Gray (Pl. Wright. 2, p. 80)—Shrubby, 
low, resinous-dotted, much branched; branchlets short, leafy; leaves 
numerous, linear or nearly so, with a slight thickening upward, 5-8” long; 
heads corymbose, terminating the branchlets; scales of the involucre in two 
series, acutish, with a brown midrib and scarious margin; rays 3-5 and 
4” long; disk-flowers 8-12; pappus coft, unequal and somewhat club-shaped; 
achenia distinctly villous. | 
This plant, from its general habit, clearly justifies Bentham and Hooker 
in retaining it with others under the old genus Ericameria, Nutt. Professor 
Gray, however, has indicated (Proc. Amer. Acad. viii, p. 635) that to do 
this involves at least two other genera in confusion —Mount Turnbull, 
Arizona, Prof. Oscar Loew. 
Bieetovia* Wricutu, Gray—Woody at base, smooth or roughish, 
several thin stems rising from the base a foot or more high; leaves linear, 
obtuse, somewhat falcate, glistening from a resinous exudation, 6-18” long; 
heads rather small; scales of the involucre coriaceous, obtuse and regularly 
imbricated in about four rows; disk-flowers 8-15, longer than the inner 
scales of the involucre; style-appendages shorter than the stigmatic part; 
achenia turbinate and hairy—Arizona. Also the rougher var. hirtello- 
scabra, Gray, with smaller and less resinous leaves (Linosyris Wrightii, 
Gray, Pl. Wright. 1, p. 95). 
*“BiGELOvIA, DC.—Heads corymbose or cymose-clustered, rarely paniculate, 5-30-flowered, 
homogamons, the flowers being all perfect and with tubular corollas. Involucre imbricated; the scales 
dry, ¢ 8 or coriaceous, chiefly destitute of foliaceous or herbaceous tips. Gdesataide flat, 
foveolaie - Sheroncalg arpa — with a chaff-like projection in the centre. Appendages of the 
style-br lanceolate to subulate or filiform. Akenes narrow, terete or angular, 
slightly j if ‘s all compressed. - Pappus simple, of copious aire aR capillary bristles as in Aplopappus, or 
fter and more equal, tawny at maturity.—Herbs or un ro with narrow olternate leaves, and 
mostly small heads of yellow flowers, etc.”—Gray, FI. ae p. 3
