344 THE FLOKA OT THE NORTHERN TERRITORY. 



" 419. 140 miles north of Northern Territory Survey Camp 14. 10 feet, 

 spreading, 2nd July, 1911." 



All other specimens of this species seen by me have very thin phyllodes ; 

 those of Nos. 383 and 419 are rather thick, and they agree with the plate in 

 Mueller's Iconography in being nearly straight and obscurely veined. 



35. A. Cowleana, Tate.—" 345. 78 miles N. i W. of Camp iii., 

 15th June, 1911. In desert. 10 feet high. Clean stem." 



" 389. 70 miles north of Camp 14. On the sandhills, 10 feet high." 

 Flowers only. 



• It seems to be this species (Horn Exped. Botany, p. 187), type from 

 Macdonnell Range, which I have not seen. It has a remarkable satiny sheen 

 with golden tips to young shoots. It is a matter for consideration as to 

 whether this species is sufficiently di tinct from A . Gunninghamii, Hook, but 

 pods are not available for a final decision. 



36. A. tumida, F. v. If .— " 497. Newcastle Waters, 7th July, 1911." 

 In flower only. 



Following are additional Northern Territory locahties, which will supple- 

 ment those in B. FL, ii., 409. 



Darwin district ; also Melville Island (W. Baldwin Spencer) ; Medium 

 shrub on sandyflat 20 miles soutti-east of Darwin (G. F. Hill, No. 433) ; Pine 

 and Horseshoe Creeks (E. J. Dunn) ; Lower part of Victoria River (R. J. 

 Winters) ; Umbrawarra (Dr. H. I. Jensen, No. 414) ; Near Wandi (Dr. H. I. 

 Jensen, No. 397). 



I have a single specimen in flower given to me by Walter Scott Campbell, 

 who collected it in 1911,, as from Thursday Island. As this would constitute 

 a new record for Queensland, I draw attention to the matter with the view of 

 it being confirmed or rejected. 



The following north-west Austrahan locahties wiU supplement the single 

 one (Isle Lacrosse) quoted in B. FL, ii., 409. Mr. Fitzgerald also quotes it from 

 Roebuck Bay and the Fitzroy River. 



(a) Artesian Range, West Kimberley (W. V. Fitzgerald, No. 1361). 



(6) Knobby's Well, West Kimberley (W. V. Fitzgerald). 



(c) Near junction of Lennard and Barker Rivers (W. V. Fitzgerald, 



No. 534). 



(d) Bamett River, near junction of Station Creek (W. V. Fitzgerald, 



No. 1098). 



(e) Dampier's Land, near Broome (Dr. E. Mjoberg, No. 132). 

 (/) Strelley River (Dr. J. B. Cleland). 



Mr. W. V. Fitzgerald, in reference to the glaucousness of this tropical 

 species, speaks of it as " a bluish looking tree of about 30 feet in height." 



He collected specimens from DiUen's Springs, East Kimberley, which appear 

 to be normal, except that the phyllodes are narrower, and both they and the 

 pods are covered with a dense silky tomentum. 



It would appear to be convenient to record this as var. pubescens. It 

 would certainly help to justify the tree being called " bluish." 



37. A. difficilis, n. sp. — " 578. 25 miles S.W. of Borroloola, 7th Sept., 

 1911." Pods only. 



" 598. Near Sandstone Ranges, Borroloola, 2nd October, 1911." Pods 

 only.
