Rh Vitis bipinnata and V. incisa, well known in the southwestern parts of the United States and Texas, were also found here. Remarkable herbaceous plants were a Nicotiana, an Orobanche (on the seacoast,) an Eustoma, several Asclepiadaceae, Malvaceae, Cucurbitaceae, Labiatae y and others. Lobelia phyllostachya has already been mentioned above, (See Note 41.)

Hasty and imperfect as this notice of the collections of Dr. Wislizenus is, it cannot but impress the botanist with the richness and novelty of the flora of these countries, and invite the arduous explorer to further exertions.

Upon the authority of Professor John Torrey, of New York, who has done me the favor to look over the botanical manuscript of Dr. Engelmann before its going to press, I add here the following two corrections:

Larrea glutinosa (n. sp., No. 10) seems to be Larrea Mexicana of Moricaud, described and figured in a work to which Dr. E. had not access.

Geranium pentagynum (n. sp., No. 6) seems to be Geranium Frémontii (Torr.) of Frémont's second report.
