Acacia undulifolia A. Cunn. 
The Wave-leaved Wattle. 
(Family LEGUMINOSvE : MIMOS>E.) 
Botanical description. Genus Acacia. (See Part XV, p. 103). 
Botanical description. Species, A. undulifoUa A. Cunn., described in G. Don. 
Gen. Hist. Dichlamydeous Plants, ii. 404 (1832) as follows : 
A. undulcefolia (Cunning. MSS. Loud. hort. brit. p. 407) stipulas almost wanting ; phyllodia, 
obliquely ovate, undulated, and marginated, 1 -nerved, glabrous, ending in a hooked or twisted point, 
bearing an obsolete gland on the upper margin at the base ; branches terete, hairy ; heads of flowers 
axillary, solitary ; peduncles beset with adpressed pili, longer than the phyllodia. Native of New South 
Wales. Lodd. Bot. Cab. 154-t. Phyllodia an inch long. The heads of flowers being so numerous, appear 
like a raceme at the tops of the branches. 
Wave-leaved Acacia. Fl. Apr. Ju. Clt. 1824. Sh. 3 to 4 feet. 
The reference " Loud. hort. brit. p. 407," is to London's Hortus Britannicus 
(1830) a work which contains no descriptions. 
The reference Lodd. lot. cab. 1544, is to Loddiges' Botanical Cabinet, vol. xvi, 
(1829) which contains a figure, but no description. The statement is made : 
" We received seeds of this in 1824 from Mr. Fraser, of New South Wales, 
with this name." (Mr. C. Eraser was then Superintendent of the Botanic Gardens, 
Sydney, and the sometime companion of Allan Cunningham, from whom he 
doubtless received the name, if not the seeds.) 
Then we come to Bot. Mag. t. 3394 (1836) where it is stated that the 
name Acacia undulcefolia originally occurs in Allan's Cunningham's MS., under 
date 1822. Cunningham's MS. description is quoted in the following words : 
Stipulis minutis acuminatis deciduis, phyllodiis late ellipticis ovatisve obliquis interdum 
subaequilateris undulatis planiusculisve acuminatis leviter parallelo-venosis glabris, mucrone attenuate 
incurvato terminatis, margine antico prope basin uni-glanduloso, capitulis solitariis geminisve axillaribus 
pedunculatis, pedunculis glabriusculis vel parce pilosis phyllodium superantibus, ramulis teretiusculis 
diffuse dependulis cano-pilosis, floribus quinqueBdis, petalis erectis apice uncinatis, stylo staminibus fere 
duplo longiore. 
It will be observed that G. Don's description already given is a fairly close 
translation of this. 
It was again described by Bentham, in Hooker's London Journal of Botany, 
i, 3i6 (1842) in Latin, and in English as follows : 
A shrub sometimes low and bushy, but often attaining a great size, and very handsome from its 
long pendulous garland-like flowering branches ; branchlets slightly angular, but soon 
terete, pubescent, hirsute, or rarely glabrous.
