76 Rediscovery of Thermopsis Macrophylla. [ZOE 
in fruit; outer involucral bracts 4-8, foliaceous, linear-oblong, 
serrate, equal, mostly twice longer than the head, reflexed; inner 
bracts 8, membranous, yellowish, acutely oval, equaling the 
disc; rays 8, golden-yellow, obovate-oblong, 2x1 cm., the tips 
entire or obscurely toothed; ovaries oblong, truncate, the edges 
retrorsly hispid; dise 2 cm. broad, 1 cm. high; its corollas light 
yellow, 6 mm. long, campanulate, the lower half abruptly con- 
tracted into a columnar base, 5-toothed; chaff linear-acute, as 
long as the florets, yellow-tipped; mature achenes black, flat, 
5 mm. long, cuneate, very slightly constricted at the summit; 
awns 2, white, 3 mm. long, or with a third awn half as long, and 
the achene then ribbed on the awned face, awns and edges of the 
achenes retrorsly barbed with rigid prickles. 
A handsome autumnal-flowering plant, common in shallow 
streams in the San Bernardino Valley, at about 1,000 ft. alt.; 
no doubt extending throughout the entire intramontane region 
of Southern California, and probably of much wider range. 
From &. chrysanthemoides Michx. and B. Nashii Wiegand it 
differs by its perennial duration, conspicuously-toothed leaves, 
constantly foliaceous outer involucres, and cernuous fruiting 
heads. All the achenes in a head are usually 2-awned, and in 
the large number examined no heads were found in which there 
were not more 2-awned than 3-awned achenes; nor were any 
4-awned achenes found, yet such may occur. 
REDISCOVERY OF THERMOPSIS MACROPHYLLA 
He A, 
BY ALICE EASTWOOD. 
TuIs-species was originally collected by Douglas, probably near 
Monterey. Not since his time has it been found, unless a plant 
collected by Mr. Joseph Clark in Mendocino County in 1876, now 
in the Herbarium of the California Academy of Sciences, should 
prove to be the same. 
Recently this species has been’ rediscovered by fie Honorable
