MISCELLANEOUS GENERA AND SPECIES. 

 PITTIERA. 



The genus Pittiera, only recently (1891) established by Prof. A. 

 Cogtiiaux, now contains four species, two of which appear here for the 

 first time. Of three of these species we have specimens in the National 

 Herbarium, one of them being a type, the other two duplicate types. 



The following species is now first described:
