This is a shrub of rather low bushy habit, with slender hairy 



branches, and globose flower-heads borne in great abundance toward 



the ends of the branches. It is quite in contrast with the other 



species illustrated here, the short narrow phyllodes and the myriads 



of small flower-heads giving it an especially dainty and delicate 



appearance. It may be grown as a pot plant or planted out, in 



either case a charming shrub. There are well-developed specimens 



of it in the central display house, range 2, New York Botanical 



Garden; from one of these the illustration was prepared. 



The narrow line-leaved acacia forms a bushy shrub with slender 

 hairy branches. The hairy phyllodes, which have a curved apex 

 and are narrowed at the base, are a half to three quarters of an inch 

 long and about a twelfth of an inch wide ; the margins are thickened 

 and there is a longitudinal nerve near the upper margin. The 

 bright yellow flower-heads, an eighth to three sixteenths of an 

 inch in diameter, are solitary on slender glabrous stalks a quarter 

 to a half inch long; there may be one or sometimes two or three in 

 the axils of the upper phyllodes. The sepals and petals are five, 

 the former distinct. The linear pods are curved, and are an eighth 

 to a sixth of an inch wide.
