in the leaves being all entire, (perhaps not a constant character;) the corolla white, (or 
nearly so,) with the tube almost twice as long as the lobes and the ovate anthers.

CONVOLVULACEA. By G. Engelmann. 
Cuscuta Catirornica, Hook. d& Arn. Bot. Beech., p. 346; Choisy, DC. Prod. IX, p. 457; 
C. acuminata, Nutt. in Herb. Acad. Philad. A well- aekie thirucl somewhat variable species. 
The tube of the corolla is generally longer than the calyx, and the lacine of the corolla longer 
than the tube. The scales are always wanting, but are sometimes indicated by semilunar 
entire or denticulate folds in the base of the corolla, corresponding with its lobes, which folds 
we find in many of our Cuscute connecting the bases of the scales. The ovary is depressed, 
the styles capillary, as long, or often much longer, than the ovary. This species is very nearly 
allied to the East Indian C. hyalina, Roth., which, according to original specimens in the herba- 
rium of the Botanical Garden of St. Petersburg, I find to be identical with C. oaypetala, 
Boissier, and not with OQ. chinensis, Lam., as is usually supposed.

islands, January 25. They differ in the leaves being smaller and less decidedly cordate than 
in the ordinary form of the plant.

Lycrium stotipum, Miers, 1. c., p. 126, ¢. 11, C.? Monument caiion; February 8. A spread- 
ing shrub, five feet high; flowers pale purple; berries crimson. This differs from the plant 
described by Miers, in the more slender habit, pale branches, and shorter pedicels. An unde- 
termined species of this genus, perhaps new, was found near San Diego, California. It is a 
spreading shrub, about three feet high, with very small farciculate spatulate-oblong leaves, 
and small white flowers on short pedicels; the tube of the corolla scarcely exserted from the 
four-toothed calyx. As Mr. Miers, who has written so ably on the Solanacex, and is about 
publishing many new species of this genus, may have received this from some other source, I 
therefore refrain from describing it more particularly in this report.
