B. Triangulaues. — Stipules setaceous or minute, not spinescent. Plijl- 

 lodia small (under | in. long), broadly falcate-ovate or triangular, with small 

 points often pungent. 



These correspoud to the subserics Triangulares of TJuinerves, with which I had formerly 

 united them as an independent series. 



166. A. sublanata^ Benth, in Ilmg. Enum. 42. A rigid shrub, woolly- 

 pubescent when younp;, at length glabrous ; branches striate. Phyilodiafrom 

 broadly triangular-falcate and mucronate to lanceolate-falcate and tapering 

 into a pungent point, rarely \ in. long, occasionally approaching in form those 

 of A. decipienSy but the upper angle much more obtuse, without any or with 

 a very minute gland, and usually much narrower and always with 3 to 5 or 

 even more nerves. Stipules small, deciduous. Peduncles longer than the 

 phyllodia, bearing each a globular head of 20 to 30 flowers, mostly 5-merous, 



' glubroue or slightly hirsute, the bract-points projecting beyond the young 

 buds. Calyx shortly toothed, half as long as the coioUa. Pod linear, much 

 twisted, about 2 hues broad.— ^. ;pravifolla, F, Muell. Fragm. i. 4, and m

 Port Gregory iu W. Australia are also like this species, but iusuffieient for determination. 



167. A. amblygona, A. Cunti.i Benth. in Hook, Land. Journ. I 332. 

 Branches elongated, ditfuse, rather rigid, terete, pubescent. Phyllodia lal- 

 cate-lanceolate or almost triangular, 3 to 4 lines long, 1^ to 3 lines broad, 

 several-nerved, the lower nerve produced into a sharp point, the upper margin 

 much curved but without any glandular angle. Peduncles rarely exccednig 

 the phvUodia, bearing each a globular head of about 10 to 15 flowei^, mostly 

 5-merou3. Sepals broadly cimeate, cohering or at length separating, luHy 

 half as long as the corolla. Petals smooth, readily separating. Pod hnear, 

 usually curved, 1^ to 2 lines broad, contracted between the seeds. Seeds 

 ovate, longitudinal; funicle thickened into a lateral oblong or club-shaped 

 aril, with a short fold below it.— ^. Nernstii, F, Muell. Fragm. iv. 3.
