No. 91. 
Acacia binerVata, DC. 
The Two-veined Hickory. 
(Family LEGUMINOS^E : MIMOSA.) 
Botanical description. —Genus, Acacia. (See Part XV, page 103.) 
Botanical description. —Species, binervata , DC. Prod, ii, 452. 
A tall shrub or a tree, attaining sometimes 30 to 40 feet, glabrous, with slightly angular 
branchlets, soon becoming terete. 
Phyllodia falcate, oblong or lanceolate, narrowed at each end, mostly 3 to 4 inches long, with 
2 or 3 longitudinal nerves and pinnately veined between them, the marginal gland below 
the middle rather conspicuous. 
Peduncles rather slender, 3 to 8, at first in an axillary raceme, but after flowering the raceme 
often grows out into a leafy branch with the peduncles at the base, each bearing a globular 
head of about twenty flowers, mostly 5-merous. 
Calyx scarcely half as long as the corolla, sinuate-toothed. 
Petals smooth. 
Pod long, flat, and very thin, about b inch broad. 
Seeds obovate, longitudinal along the centre of the pod. 
Funicle folded and dilated under the seed but not surrounding it. (B.F1. ii, 390.) 
Botanical Name.— Acacia, already explained (see Part XV, page 104); 
binervata (Latinised adjective, from nervus, a nerve or vein) denoting “ two- 
nerved,” in allusion to the two veiny in the leaves (phyllodia), a characteristic 
so readily recognised that every student o.an hear it in mind. 
Vernacular Names. —In the Illawarra district, where this Wattle is 
particularly abundant, and attains its greatest luxuriance, it usually goes under the 
name of “Black Wattle”; but, to save confusion, it would appear desirable to restrict 
the use of this term as far as possible to the forms of Acacia decurrens. 
It shares with other broad “leaved” Wattles the name of “Hickory,” and, 
in order to distinguish it, the name “ Two-veined Hickory ” is proposed. 
Aboriginal Name. —“ Myimbarr,” of the aborigines of Illawarra (New 
South Wales). 
Synonym. — A-. umbrosa, A. Cunn. in G. Don, Gen. Si/st. ii, 405. Por a 
note on some confusion which has arisen in regard to A. umbrosa, see under A. ela J %, 
Part XXII, p. 24.
