NOTES ON ACACIA. 93 



Among sandstone and quartzite rocks and gravel. 



Height 25 - 30 feet; trunk to 10 feet; diam. 9 inches. Bark 

 roughish, dark grey. Timber brown, moderately hard and heavy, 

 tough. Phyllodia 3-6 inches long, 5-7 lines broad. Spikes 1 J 

 to above 2\ inches long. Pod usually 4—5 inches long, by one- 

 third inch broad. 



Affinities to A. plectocarpa A. Cunn., and A.pachycarpa F.v.M. 

 (end of Mr. Fitzgerald's words). 



Range. We only know this species from North Western 

 Australia at present, with the single exception of the Sims's 

 Island (Northern Territory) specimen. All Mr. Fitzgerald's 

 specimens are from West Kimberley, roughly about 16° 30' 

 south latitude, and between the western boundary of the 

 Kimberley Gold-field and Collier Bay. 



The following five specimens, all either in flower or early 

 fruit, correspond to Mr. Fitzgerald's description, already 

 given: — 



1. Isdell River, near Mount Barnett, West Kimberley y 

 June, 1905 (Type). In flower and early (viscid) fruit. (W. 

 V.F. No. 1015), 



2. Base of Mount Rason. In half-grown fruit, viscid. 

 (W.V.F. No. 1293). 



3. Six miles north east of Mount Eliza. In flower (W. 

 V.F. No. 743). 



4. Pandanus Creek. In flower (W.V.F. No. 1067). 



5. Charnley River near F.B. (Camp F. Brockman) 33. In 

 early viscid fruit. (W.V.F. No. 1397). 



Mr. Fitzgerald's statement that his new species has 

 affinity with A. plectocarpa A. Cunn. and A. pachycarpa 

 F.v.M. is explained by the following specimens in fully 

 matured fruit, which, in my opinion, are all A. plectocarpa. 



1. In ripe fruit. " Erect, 10 feet high." Cambridge 

 Gulf, North of Wyndham; East Kimberley (W.V.F. No.
