214 PITTONIA. 
doubly spinulose-serrulate: heads on slender peduncles 
much surpassing the leaves, 3 inch broad or more, the 
corollas dark purple tipped with lilac: involucre small for 
the head, setaceously many-cleft: calyx with short campan- 
ulate 20-nerved tube and very long segments, these with 
almost deltoid broad base abruptly narrowed to a long 
straight setaceous awn. 
Native of Kern County, California, and southward ; re- 
lated to the more northerly T. trilobum, but very distinct; 
when well grown, exhibiting the greatest diversity of most 
beautiful foliage. 
TRIFOLIUM MAJUS. T. obtusiflorum, Greene, Fl. Fr. 31, 
not of Hooker. T.obtusiflorum var. majus, Howell in Herb. 
I long since gave a thorough diagnosis of this plant, in the 
place cited, believing it to be Hooker's T. obtusiflorum. But 
subsequent research at Kew taught me that the real obtust- 
florum, as to the specimen collected by Douglas, and there- 
fore typical, is the plant which, on the page referred to, I 
published as new, under the name of T. roscidum. This 
last, then, is but a synonym. Hooker’s figure in the Teones 
was made from the poorest branchlet of a good large speci- 
men, and fails to show any trace of the obvious pubescence. 
Such figures, completely falsifying the species which they 
purport to represent, ought not to be admitted as constitut- 
ing publication ; but, if we are to follow the questionable prac- 
tice of allowing the herbarium specimen to decide the ques- 
tion, T. roscidum, under which name the species was really 
first described, will subside. The species is far more com- 
mon than T. majus, here named as new; and my line in the 
Flora Franciscana “ originally from Monterey, Douglas, 
should be erased; for it is true only of the real obtusiflorum, 
my roscidum.
