280 MEXICO. IMalpiyliiacea. 



1. Gordonia Lasianthus. Linn — var. ? foliis integerrimis. 



Of this we find no trace among Schlechtendal's papers: We have not seen the fruit, but in every respect, 

 save that the leaves are here perfectly entire, it agrees well with the figure in the Botanical Magazine, t. 66S.

De Candolle conjectures that there are perhaps several species confused under this name, and certainly the 

 shape of the leaves in our specimens, which appear to be var. « of De Candolle, is very different from what is 

 represented by Cavanilles, Ic. 6. t. 563. In ours they are oval and obtuse, and in Cavanilles, which forms 

 De Candolle's var. y, they are lanceolate and much attenuated at both ends. The petals of this genus be- 

 come hard, dry, and persist, and have a strong middle nerve, which is canaliculate on the upper side and 

 slightly carinate on the under.

The largest leaves in the specimen before us are upwards of two inches long : those seen by Schlechtendal 

 never exceeded one and three-quarters ; which is the only point of difference we can perceive between our 

 plant and his description.
