NOTES ON ACACIA. 477 



The over-used name Acacia crassiuscula has long had a 

 fascination for me; it has been applied by different botanists 

 to at least four different plants, viz: — 



(a) By Wendland to a presumably Western Australian 

 plant which is now usually attributed (and I think correctly) 

 to A. pijcnophylla Benth. (B. Fl. iii, 368). The same plant 

 was also called crassiuscula by Meissner. 



(b) By Sieber 1 to a New South Wales plant which I have 

 since named A, obtusata Sieb. var. Hamiltoni. It is Sieber's 

 No. 464. 



(c) By Allan Cunningham 2 to a New South Wales plant 

 made by him a variety of his A. adunca. 



(d) In B. Fl. iii, 372 the A, crassiuscula Wendl., probably 

 covers several species. It should be called A. crassiuscula 

 Benth., and I am satisfied that Bentham's description 

 applies more or less to more than one species. 



A. adunca A. Ounn., has already been referred to. 



It will be observed that Bentham refers A. crassiuscula 

 to Queensland, New South Wales, and Tasmania. Let us 

 examine some of the plants referred to by him under the 

 various States. 



1. Queensland — Fitzalan's Moreton Bay specimen I 

 have not seen. Bailey ("Queensland Flora") contents 

 himself with repeating Bentham's statements in the "Flora 

 Australiensis." Certainly there is no A, crassiuscula in 

 Queensland and what Fitzalan's plant is should be enquired 

 into. 



2. Neiv South Wales — Sieber's No. 464 I have already 

 referred to. Robert Brown's Port Jackson to Blue Moun- 

 tains specimen I have been trying to trace home for many 

 years with the following result.
