This species of Acacia is very nearly related to the 
A. armata of the Hortus Kewensis; from which it is chiefly 
distinguishable by a more slender and elegant habit, and 
especially by the branches; which in A. armata are rounded 
with an even bairy surface; and in A. undulata smooth 
and angular, with a slight roughness only on the projecting 
angles. A greenhouse plant of much beauty, native of 
New Holland, and flowering in the winter months. 
For the opportunity of making our drawing, we are 
obliged to the Compte de Vandes. 
Branches twiggy, flexile, rounded, smooth, with elevated 
roughish viscid angles. Prickles (which are stipules under 
a particular form) in pairs, spreading wide, needle-shaped, 
placed under the divisions of the branches and the leaf- 
stalks, brown at the end. Leafstalks just like those of A. 
armata, but more wavy, smaller, and, as it were, moistened 
with a viscid liquor; acute. Heads of flowers globose, soli- 
tary; stalked, the length of the leafstalks. si
