Mr Don on the Ctmoniacece. 85 



first suggested the propriety of separating Caldduvia from 

 Weinmannia, states the seeds to amount to 50 in each cell; but 

 in all the specimens I have examined, both from Cavanilles 

 himself, and also from Ruiz and Pavon, I have never found 

 them to exceed 10. I regret that I have not had an opportu- 

 nity of seeing authentic specimens of the species described in 

 the Nova Genera, &c. by M. Kunth, but I could not omit in- 

 serting the characters of them in the present monograph, as the 

 greater part of them are evidently distinct from those of the 

 Flora Peruviana.
