NOTES ON ACACTA. 481 



5. Same locality and collector, No. 3126 (2nd December, 



1911). In fruit. 



6. Six to twelve feet, Yerranderie, (J. L. Boorman, July, 



1915). In flower. 



So that the range at present ascertained can be stated 

 as Mount Victoria, thence due south for about forty miles 

 as the crow flies to Yerranderie. The Nepean River locality 

 cannot be traced. 



I constitute the Yerranderie specimens the type. Named 

 in honour of Miss Margaret Plockton, the talented artist 

 of my "Forest Flora of New South Wales," "Critical 

 Revision of the Genus Eucalyptus" etc., who adds to her 

 artistic skill the capacity of working out botanical points 

 in a most intelligent manner. 



Synonyms — A. crassiuscula Benth., non Wendl., (in part). 

 A. lunata Sieb., var. crassiuscula Maiden and Betche, in 

 Maiden's "Wattles and Wattle Barks," 3rd Edition, p. 82 

 (excluding the Tasmanian reference), 



Affinities. 



1. With A. rubida A. Ounn. In such an important 

 character as the double-encircling funicle of the seed, A. 

 Flocktonice seems to be closest allied to what I may term 

 the "Acacia rubida group " (I will define what species I 

 propose to place in this group in a later paper). From A. 

 rubida, perhaps its nearest ally, it is separated by the 

 larger, gland-indented phyllodes of A. rubida, the more 

 hairy flowers, of somewhat different shape. 



2. With A. adunca A. Ounn. This is a species, figured 

 at plate 173 of my "Forest Flora of New South Wales." It 

 is one of the species brought into the "Crassiuscula" con- 

 fusion as already explained. It aud A. Flocktonice are 

 sharply separated in phyllodes and seeds (which have non- 

 encircling funicles in A. adunca) and, to a less extent, in 

 flowers.
