DESCRIPTION OF A NEW SPECIES OF ACACIA 

 FROM NEW SOUTH WALES. 



By J. H. Maiden, F.L.S., and R. T. Bakeh, F.L.S. 



Acacia pumila, sp.nov. 



(Plate XXVIII.) 



A diffuse, virgate, pubescent shrul) under afoot Iiioli as far as seen; 

 })ranches and l^ranchlets terete. Phyllodes narrow, falcate, taperin^' 

 into a recurved pungent point, narrowed at the base, trinerved, not 

 clecjirrent <is hi xi. trino.rvata ^ and less articulate, 6 lines long and 

 1 line l)road, with scattered glandular hairs on nerves and edges. 

 Stipules prominent, subulate, hairy, over 1 line long. Peduncles 

 silky-hairy, short, scarcely 2 lines long, recurved, solitary, l^earing 

 a small head of not more than i^-^y^o?6'e7'6' mostly 5-merous. Calyx 

 more than half as long as the corolla, vnth acnte almost subulate 

 lohes, prominently ribbed especially in the bud, ciliate. Petals 

 narrow, Jree, glabrous, very prominently ribbed, very marked in the 

 })ud. Pod 1 line broad, 12 lines long as far as seen, slightly 

 contracted between the seed, margins thickened. Seeds oblong, 

 longitudinal; funicle dilated from the base into a club-shaped aril 

 and consisting of about 4 ft)lds. 



/fab. — Kenthurst (R. Helms). 



Systematically this species approaches A. trinervata; but it is a 

 much smaller shrub, with a pubesc-nce on the branches and underside 

 of phyllodes; and the ph3dlodes are smaller, also falcate (not rigid) 

 with recurved points, and slightly pubescent; the peduncles are 

 also much shorter and weaker, and there are fewer flowers in the 

 heads. The characters of the cal3'^x and petals are entirely distinct 

 from th<)s(» of that species. 



The oAary is also hairy, and the stipules which are minute in 

 A. trinervata are very distinct in this species. The phyllodes and 

 the shortness of the peduncles give it some affinity to A. lanigera. 

 It differs from both, however, in the size of the pod.
