genus. The small thecae, as far as seen only 3 lines broad, and with 

 some furfuraceous puberuleuce (but they are far from mature, and 

 mainly unfertilized), and the papulose cellular ovary too much remind 

 us of Atriplex (incl. Obione). A. Endolepis of Watson, Rev. Cheuop., 

 p. Ill (of which I should like to form a distinct section), has as thin 

 and complete a sac; but there are two minute teeth at its apex, and 

 their position, along with the venation, shows that the sac is compressed 

 laterally, i.e., formed of two flat bracts. I agree with Mr. Watson's 

 view, that the sac of Grayia is obcompressed, or formed of a pair of 

 conduplicate bracts, completely united to the very tip ; and on this 

 character (along with the inferior radicle) the genus actually rests.- 

 But tiiis view demands the separation from Atriplex of a species which 

 has always appeared like a stranger in the genus, and which I proj)ose
