than half as long as the corolla, very thin, with thickened resinous lobes or teeth. 
Pod flat, about 3in. long, -|in. broad. Seeds transverse. Funicle folded and 
enlarging under the seed. 
Hab.: Inland localities. 
59. A. venulosa (veiny), Benth. in Hook. Bond. Journ. i. 366, and FI. 
Austr. ii. 388. A tall shrub, softly pubescent or glabrous and sometimes slightly 
viscid ; branchlets angular. Phyllodia falcate-oblong or lanceolate, narrowed at 
each end, mostly 2 to 3in. long, J to ^in. broad, very rigid, many-nerved and 
strongly veined, with about 3 nerves more prominent than the rest. Peduncles 
in pairs or clusters or on a very short common peduncle, mostly 2 to 4 lines long, 
rather thick, tomentose, bearing each a globular head of above 20 flowers, mostly 
5-merous. Sepals narrow-spathulate, usually united below the middle. Petals 
smooth. Pod linear, straight or curved, pubescent when young, 1 to 2in. long, 
about 3 lines broad ; valves convex over the seeds, depressed, but not contracted 
between them. Seeds ovate, longitudinal, the last 2 or 3 folds of the funicle 
thickened into a concave or 2-lobed aril under the seed. 
Hab.: Inland localities. 
60. A. melanoxylon (black wood), Ii. Br. in Ait. Hurt. Kew, cd. 3, v. 462 ; 
Benth. FI. Austr. ii. 388. A hard-wooded tree, attaining a very large size, but 
sometimes flowering when under 20ft., glabrous or the young shoots minutely 
pubescent ; branchlets angular. Phyllodia falcate-oblong or almost lanceolate, 
3 to 4in. long in the common varieties, i to lin. broad, obtuse or rarely almost 
acute, much narrowed towards the base, coriaceous, with several longitudinal 
nerves and numerous anastomosing veins. Peduncles 3 to 4 lines long, few 
together in a short raceme or sometimes solitary, bearing each a very dense 
globular head of 30 to 50 or more flowers, mostly 5-merous and often so closely 
packed in the head that the calyxes cohere. Calyx more than half as long as the 
corolla, thin and shortly toothed. Petals connate above the middle. Pod 
elongated, flat, often curved into a circle, 3 to 4 lines broad, with thickened nerve- 
like margins. Seeds nearly orbicular ; funicle very long, dilated and coloured 
from the base, very flexuose, more or less encircling the seed in double folds. —

The wood, known to the colonists under the name of “ Blackwood,” and the less appropriate 
one of “ Lightwood,” is celebrated for hardness and durability. 
A. brevipes, A. Cunn. in Bot. Mag. t. 3358, from the single specimen preserved of the cultivated 
plant described, appears to be a variety of A. melanoxylon , with longer more falcate phyllodia, 
attaining 5 to 7in. — Benth. 
61. A. implexa (plicate), Benth. in Hook. Lond. Journ. i. 368, and FI. 
A ustr. ii. 389 ; F. v.M. lc. lJcc. viii. 2. A glabrous tree, sometimes slightly 
glaucous ; branchlets terete or nearly so. Phyllodia lanceolate-falcate, more 
acuminate, more narrowed at the base and thinner than in A. melanoxylon, mostly 
5 or 6in. long or more, with several slender longitudinal nerves and fine veins. 
Peduncles few, in a very short raceme, more slender than in A. melanoxylon, 
bearing each a small dense head of numerous flowers, mostly 5-merous. Calyx 
scarcely half as long as the corolla, turbinate. Petals smooth, united to the 
middle. Pod narrow-linear, much curved and twisted, 2 or rarely nearly 3 lines 
broad, contracted between the seeds. Seeds ovate-oblong, longitudinal ; funicle 
dilated and coloured almost from the base, much folded under the seed, but not 
encircling it. — F. v. M. PI. Viet. ii. 29.
