4. Variety Leichhardtii, Benth. 
Botanical description. —Var. Leichhardtii , Benth. in B.F1. ii. 415. 
More or less hirsute, with spreading hairs. Leaflets small, narrow ; glands few. Between Archer’s 
Station and Biron, and towards the Bunya, Leichhardt. This seems to connect in some 
measure A. decurrens with A. pubescens, but it has the numerous pinnae of the former. 
It may be described as follows :— 
More or less hirsute, with spreading hairs. Decurrent angles somewhat prominent (although 
covered with hairs), hut never so marked as in var. normalis. 
Pinnce. —8-20 pairs. 
Pinnules {leaflets). —15-30 pairs. They are small, narrow ; approximately same shape and size 
as mollis. The pinnules appear to be freest from a tomentum of any of the varieties. 
Glands. —Bentham says few. But I find them rather numerous, usually commencing half up the 
primary rhachis, and continuing to the last pair. 
Flower-heads. —Apparently the smallest of the varieties. 
Flowers. —About 25 in each head. 
Calyx. —Less ciliate than in other varieties. 
Petals. —Slightly ribbed, with few hairs, which spread as they near the apex. 
Pod. —Apparently nearest to that of var. normalis. 
This might be described as an extreme form of var. pauciglandulosa. It 
resembles it strongly in general appearance, but has a profusion of comparatively 
long, weak hairs, particularly on the rliachises, which give it a rather ornamental 
aspect. The leaflets have, however, fewer hairs than var. pauciglandulosa. 
Botanical Name. — Leichhardtii, in honour of Dr. Leichhardt, the explorer, 
who first collected it. 
Vernacular Name— A “Green Wattle.” 
Synonym. — A. Arundelliana , Bailey. 
I certainly cannot follow Bailey in this matter. It is impossible to separate 
it from var. pauciglandulosa. For example, the form common on the South Coast, 
e g., Yalwal and Nelligen and Cockwhy Creek. Another transit form is Tenterfield 
to Sandy Flat, near the Queensland border. “ Green Wattle, superior as tan bark 
to Black.” It may be looked upon as var. pauciglandulosa with long hairs, or var. 
Leichhardtii as var. pauciglandulosa with short ones. It certainly is not a species 
distinct from A. decurrens. 
Flowers. —Specimens of the typical variety in the National Herbarium, 
Sydney, in flower do not bear the date of collection. The transit forms just alluded 
to were in flower,—Tenterfield to Sandy Flat, December; Nelligen, September.
