NOTES ON ACACIA. 501 



The phyllodes are imbricate to the extent that I have 

 never seen in A. lineata; indeed the appearance is very 

 different. 



Flowers in heads, on glabrous peduncles exceeding the 

 phyllodes. Oalyx narrow-linear, hairy. Petals free, 

 glabrous, five-merous. Pistil smooth and shiny. 



The pod is straight and smooth with a short funicle 

 terminating in not a large aril. The pod of A. lineata is 

 much twisted, is covered with glandular hairs and has a 

 larger more folded aril. 



It seems to me that a strong case has been made out for 

 the recognition of A. imbricata F.v.M. as a species distinct 

 from A. lineata. 



g. Acacia Bynoeana Benth. 



This species is in the " Flora Australiensis" only recorded 

 from the type locality (North West Australia), and also 

 from the Gulf of Carpentaria. 



Some years ago, I received from the late Mr. O. Walter 

 of Melbourne, an undated specimen collected by Mr. St. 

 Eloy D'Alton at Nhill, in the Mallee country of Victoria. 

 He (Mr. Walter) had marked it " calamifolia var. Wilhelm- 

 siana or nematophylla." This specimen is A. Bynoeana, 

 and there is a reference to an "A. Wilhelmsiana" from 

 the Murray Scrub by Bentham under A. Bynoeana. 



I received the same species from South Australia from 

 Mr. Walter Gill in January and December 1909. It came 

 from the same general district as Mr. D'Alton's specimen. 

 The following note was furnished by Mr. Gill : — 



"It is very common in the Parilla Forest, and all about the 

 Mallee scrub, over a wide extent of the Pinnaroo district, which 

 lies between Tailem Bend (on the Melbourne- Adelaide line) on 

 the west, and the Victorian border on the east."
