1. A form or race of A.pycnantha Benth.; or a new species, 

 for which the name of A, Westoni is proposed. 



I desire to invite attention to an Acacia which I have 

 had under attention for several years, and which I believe 

 has certain characters which sufficiently distinguish it from 

 A. pycnantha Benth., but examination of the leaves 

 (mature phyllodia) and floral organs on which descriptions 

 of species are usually based, fails to disclose differences of 

 sufficient importance for the ordinary detailed description. 

 It is in regard to other characters, which I shall bring for- 

 ward, that the necessity (in my view) for naming this 

 Acacia has arisen. 



The following is an unpublished translation of the original 

 description of A. pycnantha Benth., in Hooker's London 

 Journ. Bot. i, 351 (1842). 



" Very glabrous, shining, branchlets terete, phyllodes elongate- 

 falcate, obtuse or somewhat acute, gradually narrowed at the base 

 into a petiole, coriaceous, marginate with a rather. large gland 

 removed from the base, racemes flexuose pleiocephalous, shorter 

 than the phyllode, heads very dense, more than 70-flowered, calyx 

 a little shorter than the corolla, ovary hispidulous. Affinity is 

 A. leiophylla, easily to be distinguished by flowers often almost 

 1.00 in the head, corollas shortly prominent out of the ciliate calyx. 

 Interior of New South Wales, Mitchell. " 



I have never seen the type. Bentham, who describes 

 his own species more fully in B.F1. ii, 365, neither mentions 

 the type, nor New South Wales. He quotes Victoria com-
