I can find no characters of sufficient importance to keep Seddera as a 

 genus distinct from Cressa. The stamens, included in the dry specimens, 

 are said not to be so in the living plant. Dr. Stocks, in a note on this 

 species in the Hookerian herbarium, says that in the fresh plant the corolla 

 is rolled back, so as to expose the stamens. Wight's figure (Icones, 

 t. 136!)) is merely a glabrous state of this species, which Choisy referred 

 to Breweria.
