A 



A glabrous rigid shrub, branches pro'minently and' acutely angled or striate. 

 Phyllodia linear- oblong or lanceolate, somewhat recui*v^d-falcate, very rigid 

 and tapering into a pungent point, -^ to 1 in. long; with very thick nerve-hke 

 margins, the lower one sometimes slightly within the edge.- Stipules seta- 

 ceous, at length deciduous. Peduncles short, solitary or 2 or 3 together, 

 Bearing' each a globular head of numerous (above 4'0) flowers, mostly 5-merous. 

 Sepals di'stinct; linear-spathulale, thickened at the end, half as long as the co- 

 rolla. Petals quite sniooth. Pod not seen. 



Vir. Australia. S. coast, Baxter; Salt river, Maxwell. The aspect is nearly that of 

 A. auronitens or of some varieties of A. sicuHformis 1 It'als(r resembles A. crasmtij^ahy 

 but without the leafy stipules of that species. 



C. Unineuves.— Phyllodia with 1 nerfe oti eacih side, central or nearly 

 so. Flowers in globular heads. 



"When the phyllodia arc very narrow they are usually 4-gouous, the four angles formed ^1 

 the upper and lower nerve-hke margins and by one nerve ou each side. 



A rio-id bushy shrub: 



tly 



nerve, and scarcely thickened nerve-like margins. Stipules short, setaceous or 

 pungent. Peduncles nearly as long as the leaves, b'eariug each a globular 

 hcarl of about 15 to 20 flowers, mostly 5-merous. Sepals distinct, linear- 

 spathulate, very thin. Petals, soon separating, striate but not thick, rod 

 about I in. long, and 3 lines broad, straight, very iTiick, not contracted be- 

 tween the seeds, with very broad smooth margins, and obscurely veined be- 

 tween. Seeds thick, obovoid; funicle short, not folded, expanding into a 

 short broad concave aril at the end of the seed.
