Ord. L. GESNERIACE.E. Rich. 

 1. Gesneria Deppeana. Schlecht. in Linncea, 5. p. 110. 



Allied to G. elongata, H. B. K., but far less hairy, with shorter leaves, smaller flowers, and a longer 

 upper lip. 



1. Trevirania parviflora ; foliis ovatis uniformibus grosse inasqualiter serratis, pedun- 

 culis aggregates gracillimis, corollse limbo parvo erecto-patente. 



The flowers are very much smaller than in the well-known T. coccinea {Cyrilla pulchella, Bot. Mag. t. 

 374), and the limb is extremely short, and scarcely spreading. It is still more different from T. grandiflora, 

 Schlecht. in Linnasa, 8. p. 247 ; and equally so from T. heterophylla, Mart. : both of them likewise 

 Mexican species.

Ord. LV. GENTIANEA. Juss. 



1. Erythraea Mexicana ? 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 flowers are twice the size of the other kind (from Talisco), but we do not find any- 

 structural difference.
