The numerous leaves on our specimen are nearly all fascicled on 

 opposite abbreviated branches, so that I can only infer their arrange- 

 ment on elongating branches from the opposition of the fascicles. 

 At the base of the fascicles are very minute ovate brownish free 

 squama?, which may be, and probably are, stipular. 



The plant in general character recalls Gymnocarpos, of Forskal. 

 Dr. "Bayley Balfour describes from Socotra two new genera of this 

 Natural Order : IIa7ja, an annual herb with solitary basilar ovules ; 

 and Lochia, frutescent, but flowers not involucrate, and also with a 

 solitary ovule suspended from a basilar funicle. Probably a re- 

 arrangement of the tribes of the Order may become necessary m view 

 of these additions.— D. Oliver.
