 C. F. Newconibe.) 



Dr. Greene's new genus, Nesodraba, 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. megalocarpa is known only from Dr. Newcombe's speci- 

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

 borea.
