Macbride — Certain Borraginaceae 41 
islong. The Asian species of this group are very closely related and 
the nomenclature is involved. Lipsky proposes a new species (EF. 
polymorphum) apparently without regard for any rules of priority, 
which he uses for a veritable waste-basket species. However, since 
our plant has one very evident character (the short style) which 
separates it from all of the Asian forms, it seems best to regard it 
as a species.

It is necessary in accordance with the now almost universally 
accepted generic limitations in this family, as outlined by Dr. 
Greene in Pitt. i. 8 et seq., to set aside this natural group of species 
as a genus, allowing them to stand on a par with the other genera 
carved from the obviously heterogeneous group, Krynitzkia. Con- 
sidered generically, then, these species stand intermediate between 
the genera Allocarya and Plagiobothrys. From Cryptantha (the 
proper name for the restricted Krynitzkia), to which one of them 
has been referred, they are most at variance, not only in habit, but,
