Ord. L. GESNERIACEiE. liicli. 
1. Gesneria Deppeana. Schtecht. in Linncea, b.p. 110. 
Allied to G. elongata, H, B. K., but far less hairy, with shorter leaves, smaller flowers, and a longer 
upper lip. 
I. Trevirania parviflora ; foliis ovatis uniformibus grosse inaequaliter serratis, pedun- 
culis aggregatis gracillitnis, corollae limbo parvo erecto-patente. 
The flowers are very much smaller than in the well-known T. coccinea {Cyi'illa pulchella, Bot. Mag. t. 
374), and the limb is extremely short, and scarcely spreading. It is still more different from T. grandiflora, 
Schlecht. in Linnaea, 8. p. 247 ; and equally so from T. heterophylla. Mart. : both of them likewise 
Mexican species. 
Ord. LI. ERICE^. Juss. 
1. Clethra obovata. Ruiz et Pav. FI. Per, t. 38 i C. tinifolia. Schlecht. in Linncea, 
5. p. 127. {non Sw.). 
Ord. LII. SAPOTE.^. Juss. 
1. Lucuma? ferruginea ; foliis obovatis obtusis in petiolum attenuatis subtus (juniori- 
bus sericeo-) ferrugineis, floribus aggregatis. 
Ord. LIII. ASCLEPIADE^. Br. 
1. Sarcostemma Cumanense? H. B. K. Nov. Gen. Am, 3. p. 195. 
Hab. Acapulco. — The leaves are glabrous ; in other respects it seems to agree with Humboldt’s Cumana 
plant. 
1. Asclepias glaucescens. H. B. K. Nov. Gen. Am. 3. />. 190. t. 227. — Hab. Talisco. 
Ord. LIV. APOCINE^. Br.

1. Nerium orformw. i.— flore pleno. — Acapulco: cuUiv. 
Ord. LV. GENTIANE.L:. Juss. 
1. Erythraea ilfm'cam ? Griseb. ined. 
With our imperfect specimens, we dare not venture upon offering a character of this plant, of which there 
are two varieties, if not two distinct though closely allied species : both having the habit and paniculated stem 
with divaricated branches of E. Mexicana, Griseb. in Herb, nostr. ; but the calyx is more deeply cleft. In 
the one from Tepic, the flow'ers are twice the size of the other kind (from Talisco), but we do not find any 
structural difference.
