DESCRIPTION OF A NEW SPECIES OF ACACIA 
FROM NEW SOUTH WALES. 
By J. H. Maiden, F.L.S., and R. T. Baker, F.L.S. 
Acacia pumila, sp.nov. 
(Plate xxviii.) 
A dififuse, virgate, pubescent shrub under afoot high as far as seen; 
branches and branchlets terete. Phyllodes narrow, falcate, tapering 
into a recurved pungent point, narrowed at the base, trinerved, not 
decnrrent as in A. trinervata, and less articulate, 6 lines long and 
1 line broad, 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, bearing 
a small head of not more than 1 0 flowers mostly 5-merous. Calyx 
more than half as long as the corolla, with acute almost subulate 
lobes, prominently ribbed especially in the bud, ciliate. Petals 
narrow, free, glabrous, very prominently ribbed, very marked in the 
bud. 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 folds. 
Hob.— Kenthurst (R. Helms). 
Systematically this species approaches A. trinervata; but it is a 
much smaller shrub, with a pubescence on the branches and underside 
of phyllodes; and the phyllodes 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 calyx and petals are entirely distinct 
from those of that species. 
The ovary 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.
