ASCLEPIADEZ. 
By Dr. GEORGE ENGELMANN. 
Asciepias EROSA, Torr. Bot. Mex. Bound. 162. (A. leucophylla, Engelm. 
Am. Naturalist, 9, 349; Gray, Bot. Calif 1, 476; Syn. 94.)—Fort Tejon. 
Ascuepras Mexicana, Cay. Gray, Proc. Am. Acad. 12, 71; Syn. 96. 
(A. fascicularis, Decaisne in DC. Prod. 8, 469; Gray, Bot. Calif. 1, 475.)— 
Lake Elizabeth, Rothrock (190), 1875. Very closely allied to A. verticillata ; 
the flowers, though a little larger than in the common forms of that species, 
are scarcely to be distinguished from it. I find, however, the top of the 
rounded hoods more reflexed, and the horn comes from near the base of the 
hood, while in verticillata it is attached to the whole lower third or half. 
But A. Mexicana is altogether a stouter plant, with spreading, or at last 
recurved, usually conduplicate leaves, bearing the umbels in a terminal 
corymb. 
GENTIANEZ. 
By Dr. GEORGE ENGELMANN. 
GENTIANA SERRATA, Gunn. Fl. Norveg. 10, var. HoLopETALA, Gray, Fl. 
Calif. 1, 481; Syn 117—Simple, or with many simple, ascending branches 
from the base, and long, naked peduncles; lobes of the corolla entire or 
with few notches.—Southern Sierras, Kern County, at 10,000 feet altitude. 
Easily distinguished from G. simplex, Gray, by the oval, rough ovules and 
seeds, while those of the latter species are lanceolate, smooth, and tailed at 
both ends.
