302 MEXICO. IGeniianece. 



Ord. L. GESNERIACEiE. 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 parvijlora ,• foliis ovatis uniformibus grosse inasqualiter serratis, pedun- 

 culis aggregatis gracillimis, corollas 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 Linnsea, 8. p. 247 ; and equally so from T. heterophylla, Mart. : both of them likewise 

 Mexican species.

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.
