think, by earlier authors; but that assemblage does not 
include the present plant. Its charaeteristies of foliage, 
calyx, and especially of its reduced and blunt-lobed involucre, 
mark it well as a species. It has been collected apparently 
only by my zealous pupils, Messrs. Victor K. Chesnut and 
A. B. Simonds, of the University of California. Its locality 
is in the Oakland Hills, between Oakland and the Moraga 
Valley, towards Mt. Diablo, where it was found in April of 
this year. 
SYRMATIUM NUDATUM. Shrubby, slender, diffusely branched, 
the branches a few inches to a foot long, rigid and a little 
flexuous, green-barked and glabrous, the nodes an inch apart : 
leaves 3-foliolate; leaflets oblong, acute, 1—2 lines long, 
appressed-puberulent; stipular glands large, blackish: pe- 
duneles very short or almost obsolete, bractless, 1—2-flowered : 
corolla 2 lines long: calyx-teeth subulate, straight, erect, 
somewhat unequal, the longest about half the length of the 
tube: pod minute, pubescent, the body well exserted, curved 
into more than a semicircle and tipped with a nearly straight 
filiform persistent style. 
Cedros Island; collected many years ago by Dr. Veatch, 
and again in 1885 by the present writer.

obtuse, 2—3 lines long: racemes short-peduncled, few-flower- 
ed: corolla white, 4—5 lines long, the campanulate calyx 
half as long, its teeth subulate from a broad base and nearly 
equalling the tube: pod fleshy, 1-celled, a half-inch long, 
oblong, obeompressed and surrounded by a narrow turgid

Hanson’s Ranch, San Rafael Mountains, Lower California,

to A. caryocarpus, but is smaller in all its parts, and the
