Gardner's n. 1041 from Pernambuco, and 1317 belong to 

 Evea of Aublet, as characterized by Chamisso, (Linnsea ix. 

 237), the ovary and fruit, however, of Aublet's original 

 species are as yet unknown. One species (n. 1041,) is the 

 same as Salzmannia nitida, DC, the other, (n. 1317,) ap- 

 pears to be Chamisso's Evea Brasiliensis, The ovary in 

 both is bilocular, with one pendulous ovule in each cell ; the 

 fruit as described by Chamisso. 



Gardner's n. 451 and 452 from the Organ Mountains, are
