Dr. Greene's new genus, Nesodrdba, includes three 

 species, one of which, N. grandis, has long been a puzzle to 

 botanists, having been by the earlier botanists referred to 

 Cochlearia and by the later, with less reason, to Draha. 

 N. megalocarjpa is known only from Dr. Newcombe's speci- 

 mens. N. grandis is common in herbaria as Draha hyper- 

 horea.
