A. acuminata has smaller phyllodes, with the margins 

 often ciliate. Fruits of A. acuminata are very rare in 

 collections; they were described by Bentham, and also by 

 Mr. W. V. Fitzgerald in Journ. W. A. Nat. Hist. Soc, p. 52 

 (May, 1904). I have received fruits from Kununoppin, 

 January, 1917 (Dr. F. Stoward) and they present a very 

 considerable similarity to those of A. lasiocalyx, additional 

 evidence of the affinity of the two species. The A. acu- 

 minata pods I have are pale brown, glabrous, with valves 

 more woody, more embossed by the seeds, and the rims 

 more marked. 



A. Oldpieldii F.v.M., Fragm. iv, 7. 



Bentham (B. FI., ii, 404) considers this to be a synonym 

 of A. acuminata, 



I have been favoured by Professor Ewart of the Melbourne 

 Herbarium with a sight of the type. The material consists 

 of a twig with a few mature phyllodes with some small 

 young shoots with golden pubescence, some loose phyllodes, 

 a fragment of a spike of flowers (loose), and a detached 

 pod with ripe seeds. Such material is obviously unsatis- 

 factory. At the same time, it is very desirable that des- 

 criptions of species should be investigated, and I therefore 

 submit the following notes. 



I do not disagree with Bentham's opinion that A. Oldfieldii 

 is synonymous with A. acuminata Benth. 



Phyllodes 2J — 4J inches long, \\-2\ lines broad, as seen 

 by me. The old phyllodes are quite glabrous, but the young 

 growth is golden pubescent as in A. acuminata. Branchlets 

 angular. 



Flowers 4-merous. Calyx yellow pubescent, denticulate. 

 Corolla short-glabrous. Pods 2-4 inches long, 1 — 1J lines 

 broad. Seeds elliptical and longitudinally arranged. They 

 are not the pods of A. acuminata.
