PLATYSTEMON AND ITS ALLIES. 187 
times as in the type, sometimes inclining to be wrinkled 
rather than lineolate. 
Species apparently common from the southern borders of 
San Diego Co., to southern Montery Co., if the variety is 
really not a proper species. The type is from Witch Creek, 
San Diego Co., 24 May, 1894, and is in my own herbarium. 
There is a similar plant, quite typical, in U. S. Herb. from 
Santa Ysabel, also in San Diego Co., by H. W. Henshaw, 
25 Apr., 1893. Nearly like these is a sheet in Herb. Calif. 
Acad. by Miss Eastwood from somewhere near the boundary 
line between Santa Barbara and San Luis Obispo counties, 
6 May, 1896. 
The var. sanctarum I find represented only in Herb. 
Calif. Acad.; two sheets, from the Santa Lucia Mountains 
by Miss Eastwood, in 1897, and one purporting to have 
been sent from Santa Barbara in 1901, by Elwood Cooper. 
This form is so unlike the type in habit, that I should will- 
ingly have assigned it the rank of a species were not the 
stamens and carpels so almost exactly those of typical P. 
obtectus. 
40. P. acuratus. Stoutish, a foot high or less, only moder- 
ately pilose or hirsute, branched at base only and the leaves 
short: corollas cream-colored, very large, at least 1} inches 
broad in expansion but with turbinate base, the petals not 
notably unequal as to breadth and all obovate above a 
cuneate claw-like base: stamens excessively many and un- 
equal, the filaments of all linear-dilated and petaloid but 
acute under the comparatively broad and short anther : 
carpels about 16 or 18, not known in maturity. is 
The best specimen seen of this new species, which is 
unique in the genus by its uniformly acute filaments, 
has been distributed by C. A. Purpus, from the Middle 
Tule River, southern California, being a part of his n. 5006
