Unfortunately there are several so-called Hickories in this State, and, therefore, 
care is necessary to indicate the right one. That Hickory which looks like a pepper- 
tree, and which is found on the hanks of watercourses and in gullies in the Blue 
Mountains, and also at Picton, Bargo, Mittagong, and other places in the Southern 
districts, is Acacia elata. Most of our Hickories (and Acacia pennineryis is no 
exception), however, are phvllodinous. Amongst those which are known as Hickory 
in different places, are Acacia binervaia (one of the Black Wattles), and even the 
Blackwood ( Acacia melanoxylon ) and the closely-allied Acacia implexa. 
Aboriginal Name.—I know of none which can he recognised with certainty. 
SyilOliyillS.—I have already explained the unfortunate confusion which has 
arisen in regard to this species. To recapitulate, we have :— 
1. Acacia pennine rvis, Sieb. 
(a) A. impressa, Lindl. Bot. Beg. t. 1115, and Lodd. Bot. Cab. t. 1319, 
based on A. Cunn. MSS. 
(b) A. pennine rvis, Sieb , var. lanceolata , H. T. Baker. 
2. Variety falciformis, Bcnth. (the Tanning Wattle). 
(a) A. falciformis, DC. 
(b) A. astringens, A. Cunn. 
(c) A. penninervis, vars. normalis and glauca, It. T. Baker. 
3. Variety anguslifolia, Maiden. 
Leaves. —It is worthy of note that in some districts in which Mountain 
Hickory occurs the bark has never been stripped and tried, for the reason that 
people do not look upon it as a Wattle, imagining it to be a Gum-tree because of the 
appearance of its leaves (phyllodes)! This state of things is passing away, as the 
bark is now becoming appreciated in certain quarters, to my personal knowledge, 
and it is only another instance of the unknown wealth waiting to be known, and 
therefore utilised. 
My readers will observe from the plates how variable in size and contour 
are the leaves (pliyllodia) of the Mountain Hickory. It is, in fact, a very variable 
species, but it may be usually known by means of the thickened dot or gland which 
is found a little distance along the rim (or marginal vein) of the leaf, and from 
which another vein extends, in a curved manner, to the leaf-stalk. A small leaf¬ 
shaped enclosure, varying in size, is thus partitioned off out of the area of the 
leaf itself. 
A specimen, from near Moruya, has very narrow leaves (variety angustifolia ) 
varying in breadth from a quarter to half an inch, and from 8 inches to 12 inches 
in length. Another, from Mount Dromedary, has its leaves 8 inches long and 
2|- inches broad. The average size, however, may be given as 5 inches long and 
1 inch broad. This will explain why different trees are known as narrow-leaved and 
broad-leaved Mountain Hickory respectively,
