Description OF THE Species, Acacta Riceana. A sHRvs, from — 
three to four feet high, with somewhat of a furze-like aspect; the 
branches rather elongated, becoming very slightly deflexed. LEaves 
(phyllodia) alternate, horizontal, about one inch long, articulate, 
linear-subulate, slightly succulent, but compressed, rigid, and mucro- 
nato-pungent, of a dark green, with the surface covered with minute 
white dots, one-veined in the middle, but having also another vein on 
each edge, and occasionally a trace of one between the mid-vein and 
d The pungent apex of a dark brown. FLowenrs in axillary 
and solitary spikes, on short contracted branches, but as each of these 
latter bear from one to four spikes, these appear to be more or less 
crowded in the middle of a tuft of leaves, seated in the axils of those 
leaves where the contracted branches are developed. PrpUNCLES 
yellow, nearly one inch long, bearing from five to fifteen scattered or 
occasionally sub-verticillate flowers, with a small ferruginous bract at 
the base of each. The flowers are polygamous, of a pale citron 
colour. CaLyX monosepalous, campanulate, three- rarely four-lobed, 
the lobes obtuse, shortly ciliate. Coroxta tri-petalous, (rarely | 
quadri-petalous), the petals twice as long as the calyx, and alternate 
with its segments, ovate, revolute, one-nerved. STAMENS very nume- ~ 
rous, longer than the petals, scarcely perigynous, and nearly free. 
ANTHERS two-lobed, sub-globose. Ovary free, ellipsoidal, villous. 
Sty e glabrous, filiform, longer than the stamens, very little curved
