G. pumiba is readily distinguished from the six other known species in the 

 genus by its small, coriaceous, obscurely nerved leaves. Its leaves somewhat re- 

 semble those of Salpincies kcUmiaefolius Woodson rather than any species of 

 Galactophora ; they are a little differently shaped, however, narrowed and obtuse 

 at the base rather than rounded or subcordate. and more generally rounded at 

 the apex. 



Galactophora schomburgkiana var. megaphylla Monachino, var. nov. 



Haec varietas a var. schomburejliana praecipue recedit foliis multo majoribus. 

 7-15 cm longis, 6-11 cm latis. et lobis ealycis longioribus 12-15 mm longis.
