320 THE FLOEA OF THE NORTHERN TERRITORY. 



Bentham points out that Mueller gave the name of A. tenuissima to two 

 species, the other being given, at p. 135 of Mueller's paper, the name of A. 

 tenuissima. It came from Sturt's Creek. 



In B. Fl., ii, 401, Bentham makes it var. (?) tenuissima of A. xylocarpa, 

 A . Ctmn. 



In B. FL, ii., 339, Bentham records A. juncifolia from " Islands of Gulf of 

 Carpentaria, R. Brcmm," which I have not seen,* and also from " barren stony 

 places on the Mac Arthur, Mueller," the unsatisfactoriness of v/hich I have 

 just shown. 



In his " Second Census," Mueller recorded A. juncifolia for N.A., but 

 Professor Ewart informs me that there is no specimen from the Northern Ter- 

 ritory in the Melbourne Herbarium. 



I recommend that A. juncifolia be not admitted to the record of the 

 Northern Territory species without additional evidence. If it occurs in the 

 Territory, it will probably be found in the south-eastern part of it, rather than 

 on the northern coast. 



4. A. lycopodifolia, A. Cunn. (123). 



Victoria River ; it had already been collected in Arnhem Bay, another 

 Northern Territory locahty. I received it from the Lower Victoria River in 

 1913, from R. J. Winters and E. J. Dunn. 



Var. glabrescens, Benih. : Collected by Mueller at the Victoria River, who 

 described it in B. Fl. ii., 342, from material named A. asperulacea, by Mueller. 



5. A. galioides, Benth. (123). 



Victoria River, also Islands of Gulf of Carpentaria (R. Brown). 

 A. asperulacea, F.v. M. (123), is a synonym of A. lycopodifolia, A. Cunn., 

 var. glabrescens, Benth. See above. 



6. A. subternata, F. v. M. (124). 



Upper Victoria River, Roper, and Limmen Bight Rivers, 



7. A. salicina, Lindl. (126). 



Arnhem's Land to the Roper River. This has proved to be a widely dis- 

 tributed and very variable species. Reference mav be made to my " Forest 

 Flora,' N.S.W.",Va.it 39, p. 146. 



8. A. Sentis, F. v. M. (128). This species is not synonymous with A. 

 decora, Reichb., as Bentham, who edited Mueller's paper, thought at the time. 



Victoria River, Arnhem Land, Gulf of Carpentaria. A widely diffused 

 species in the drier parts of Australia. 



A. pendula, A. Cunn. (133). 



Mueller records specimens from Sturt's Creek without flower or fruit, and 

 therefore (as he points out) doubtful. 



The species is very widely distributed, but I know of no authentic record 

 of it for the Northern Territory. 



9. A. stenophylla, A. Cunn. (133). 



Hooker's and Sturt's Creeks. Since then found to be widely distributed in 

 Australia. 



10. A. dineura, F. v. M. (130). 



Sources of Roper and Limmen Bight Rivers. In editing Mueller's paper, 

 Bentham agreed that the species was valid, but in B. Fl., ii., 391, he placed it 

 under A. binervata, DC, the specimens being " small and in fruit only." 



* Unless it is " Acacia juncifolia, Benth : received from Kew without specific local- 

 ity." Mr. J. F. Bailey has kindly favoured me with a specimen from the Queensland 

 Herbarium. It probably came from Islands of the Gulf of Carpentaria, R. Brown, 

 and it is A. AlUninna. Maiden, n. sp. See below, p. .'!.30. The pods are so immature as 

 to cause a description to be unsatisfactory.
