510 XLIII. LEGUMINOS^E. [ Acacia . 
Distinguished from A. glauccscens by the very angular branches, the larger phyllodia and their 
venation. — Benth. 
Var. longispicatu. Branches stout and still more angular. Phyllodia 6 to 8in. long, 1 to 2in. 
broad. Spikes 3 to 4in. long. — .-1. longispicata, Benth. in Mitch. Trop. Austr. 298. — Near Mount 
Pluto and Lake Salvator, Mitchell. 
100. A. leptocarpa (slender pods), A. Cunn.; Benth. in Hook. Bond. Journ. 
i. 376, and FI. Austr. ii. 407. Usually glabrous ; branchlets at first slightly angular, 
but soon terete. Phyllodia falcate-lanceolate, narrowed at each end, 4 to Gin. 
long, 4 to 8 lines broad, with 3 or more fine slightly prominent nerves and very 
fine parallel ones between them, rarely anastomosing, and not nearly so close as 
in several allied species, the interval between each several times the breadth of the 
vein. Spikes 1-J- to 2in. long, solitary or in pairs. Flowers mostly 5-merous, 
usually glabrous, not very close. Calyx short, sinuate-toothed. Petals smooth, 
united at the base. Pod linear, straight or nearly so, several inches long, 1| to 
2 lines broad ; valves coriaceous, convex over the seeds, contracted between them. 
Seeds longitudinal ; funicle with the last 2 or 3 folds dilated into an oblong cup- 
shaped aril, nearly as long as the seed, but embracing its base only. 
Hab.: Cape York, II'. Hill ; Endeavour River and Cape Flinders, A. Cunningham ; Shoalwater 
Bay, R. Brown ; Port Denison, Fitzalan. 
Twine made from the bark. — Roth. 
Wood dark-brown, close-grained, hard and prettily marked ; useful in turnery and cabinet- 
work. — Bailey's Cat. Ql. II T oods No. 140b. 
101. A. polystachya (spikes numerous), A. Cunn.; Benth. in Hook. Bond. 
Journ. i. 376, and FI. Austr. ii. 407. Glabrous, young branches angular, but soon 
terete. Phyllodia falcate-oblong or lanceolate, narrowed at each end, 6 to lOin. 
long, 1 to l^in. broad, very oblique at the base, with 3 to 5 prominent nerves, 
the intermediate ones fine and numerous, but not very closely packed and 
occasionally anastomosing. Spikes solitary or 2 or 3 together, slender, glabrous, 
1 to 2in. long. Flowers mostly 5-merous, not very close. Calyx sinuate-toothed, 
not half so long as the corolla. Petals united to the middle. Pod very flexuose, 
but not spiral, several inches long, 5 to 6 lines broad ; valves fiat, thinly coria- 
ceous. Seeds longitudinal in the centre of the pod ; funicle long, dilated and 
colored, the last 2 folds more than half encircling the seed, the next 2 extending 
along the other side so as nearly to surround it. 
Hab.: Islands of the Gulf of Carpentaria, R. Brotvn : Port Bowen, A. Cunningham ; Endeavour 
River, IF. Hill. 
Very like A. leptocarpa, but phyllodia usually larger and the pod and seed different. — Benth. 
Wood dark, close-grained, prettily marked. Bark contains 7‘59% of tannin, Staiger. — Bailey's 
Cat. Ql Woods No. 140a. 
102. A. holcocarpa (pods grooved), Benth. FI. Austr. ii. 408 ; F. v. M. Ic. 
Dec. xi. 5. Glabrous; branchlets slender, terete. Phyllodia broadly falcate, 
narrowed at both ends and very oblique at tbe base, 4 to 5 or perhaps 6in. long, 
1 to Jin. broad, not glaucous, with 2 or 3 fine rather prominent nerves and very 
numerous, very fine, closely packed parallel veins between them. Spikes nearly 
sessile, about lin. long, slender but dense. Flowers mostly 5-merous, but some- 
times 4-merous, small. Calyx deeply lobed, pubescent. Pod long and slender, 
straight or slightly curved, nearly terete, longitudinally sulcate-striate, about 
2 lines diameter. Seeds oblong, longitudinal, embedded in what appears to be a 
dried pulp ; funicle short, scarcely folded, dilated into a short more or less 
oblique aril. 
Hab.: Port Bowen and Thirsty Sound, R. Brotvn; Trinity Bay, Hill; Rockingham Bay, 
Italia chy . 
Phyllodia precisely like those of A. crassicarpa, but the pod very different.— Herb. R. Brown
