62. A. tihcinella^ Benih. in Lbinaa, xxvi. 613. A low bushy shrub, 

 glabrous or the young slioots minutely pube'scent; branches terete or slightly 

 angular. Phyllodia shortly linear-subulate, terete or nearly so, mostly about 

 1 UK lono;, faintly 1- or 3-nerved on one side", narrowed at the base and as it 

 were petiolatfe. Stipules minute, deciduous. Peduncles 2 to 4 lines long, 

 rather slender, solitary or in pairs, bearlni? each a small globular head of about 

 20 flowers, mostly 5-merous. Sepals distinct, natrow-spathnlate. Petals smooth. 

 Pod (from the remains on one specimen) not above \^ lines broad, not con-
