In A. sessilijiorus there occur small leaves 1-1| in. long on some shoots and in 

 some axils. The material for A. parvifolius is scanty, and I suspect that with more 

 it and A. sessilijiorus may hereafter be judged to be one. A. trisulcus, Nees, the type 

 of the genus, differs little but by the persistent grey pubescence. 



3. A, Zenker!, C. B. Clarke. Glabrate; innovations minutely
