14 DESCRIPTION OF A NEW SPECIES OF ACACIA, 



an inch. Leaf-racbis generally 1-1 J inches long. Pinnules seldom 

 exceeding an inch in length and some shortened to half an inch. 

 Leaflets ^ to ^ inch long. Racemes mostly axillary and solitary, 

 usually much longer than the leaves. The rachis of each raceme 

 very flexuous. Flowers in the headlets not very numerous. Fruit 

 IJ-S inches long, ^-^ inch broad, usually devoid of conspicuous 

 marginal sinuosity, the valves of rather thin texture. Seeds 

 mostly about ^ inch long. 



This species differs from A. puhescensm much shorter indnment, 

 less closely approximated and fewer pinnules, somewhat channelled 

 and distinctly pointed leaflets, rachis-glandules present at all the 

 ])innules, broader racheole, larger headlets of flowers on shorter 

 stalklets, glabrous, shorter and seemingly never paniculated 

 racemes ; but in carpological characteristics both species are much 

 alike, except that the valves of A. puhescens are less coriaceous, 

 narrower, more constricted between the seeds, while the seeds 

 themselves are proportionately narrow and placed longitudinally. 

 From A. Baileyana, which was more recently collected by Mr. 

 Garland and Mr. Coker also between the Marrumbidgee and 

 Lachlan Eivers, our new species is distinguished chiefly in 

 pinnules always more numerous to each leaf and much narrower 

 in outline, in leaflets less blunt, with the median line very faint and 

 not near the anterior margin, neither glaucous nor flat, in racemes 

 shorter, with also less elongated stalklets to the headlets, in fruits 

 narrower with less space left between the seeds and the sutures of 

 the valves. 



From A. polyhotrya^ recorded now also from Wybong Creek, a 

 tributary of the Hunter River, the new congener is distinguished 

 by leaves much smaller and always glabrous, with neither bluntish 

 nor flat and also less inequilateral leaflets, by fruits of lesser size 

 with seeds placed more longitudinally, and by the funicle enlarging 

 into a very conspicuous strophiole. 



From A. leptoclada it recedes strikingly in the absence of copious 

 long spreading hairlets on the branchlets and headlets, in leaves 

 more numerously pinnulate and probably also in characteristics of 

 well-developed flowers and fruits, neither of which are as yet
