STUDIES IN THE COMPOSITA. 267 
Colton, G. W. Dunn. Only what seem to be long decum- 
bent or reclining branches of this interesting plant are seen 
in the herbaria. The collectors, and botanical residents of 
southern California have not been interested in it, and their 
labels tell nothing of its habit or dimensions. The heads 
in size and showiness of ray emulate those of B. formosa of 
the East. Mr. Wiegand appears to have referred this to 
B. Nashii, through oversight of its peculiar habit and very 
decided characters. I suspect the root to be perennial. 
"B. Kxrroaar. Stems several feet high, much branched, 
very leafy, the branches and peduncles sparsely scabrous 
or hirsute: lowest and largest leaves 5 to 8 inches long, 
lanceolate, coarsely and somewhat remotely serrate, of 
notably thin texture, sometimes connate at base, other- 
wise auricled: heads large, on short leafy branches or 
peduncles: bracts of outer involucre oblong-linear, twice as 
long as the inner and widely spreading, the inner closely 
dark-lineate almost to the margin: rays less conspicuous 
than in its Pacific coast congeners: disk-corollas short, the 
slender tube twice as long as the campanulate limb: 
achenes olive-green, rather strongly striate, 3-awned and 
4-awned, the awns unequal, all slender and slenderly 
aculeolate. ~ 
Plant formerly common along streamlets and margins of 
lakes in the immediate vicinity of San Francisco; now if 
not wholly extinct, at least the earlier stations all oblit- 
erated by the city’s growth; always, until Mr. Wiegand 
took it up, catalogued as B. chrysanthemoides; though the 
heads are always nodding in fruit; and Dr. Torrey, as 
the labels of the specimens collected on the Wilke’s Expe- 
dition, being in his handwriting show, more correctly 
referred them to B. cernua, designating them as a variety
