 times resembles A. Uretifolia, but the stipules are not spinescent, the phyUodia are pronii- 



nently 1-nerved, and the pod is quite different.

 slmib, the branches not very stout, nearly terete, glabrous or pubescent. 

 Fhyllodm scattered, linear-subulate, erect or spreading, rigid and taperin-' 

 luto a pungent point, mostly ^ to f in. long, with 1 or rarely 2 prominent 

 nen-es on each side. Stipules minute. Peduncles mostly solitary, short, 

 beanng each a small globular head of 15 to 20 or more flowers, mostly 5- 

 merous. Sepals distinct, linear-spathulate, with dark tips, half as long as 

 ttie corolla. Petals free, smooth. Pod not seen.— Meissn. in PI. Preiss.

&ome specimens have almost the aspect of ^. striatula, but differ in their 1- or rarely 2- 

 aencdphjllodia, and very short peduncles. 



^5. A* ingrata, Bmlh. Branches rio-id, dabrous or minutely pubes- 

 , ^"ytiodia divaricate or reflexed, very rigidly linear-subulate, with a

 prominent nerve on each side. Peduncles short, solitary or 2 together, bear- 

 % caeli a small globidar head of about 5 or 6 flowers, mostly 5-merous, 

 talyx very short and broad, thin, slightly sinuate-toothed. Petals smooth, 

 ^ubout raised midribs, cohering at the base. Pod unknowm
