322 THE FLORA OF THE NORTHERN TERRITORY. 



This is a puzzling, uncertain species. In the paper before the Royal 

 Society of New South Wales just referred to, I have discussed, at some length, 

 " What is Acacia oligoneura, F. v. M. 1 " 



21. A. toruTosa, Benth. (139). 



This is a case in which a new species in Mueller's paper is attributed 

 to Bentham. (See B. Fl., ii., 405). 



Bentham, in editing Mueller's paper, synonymises it with A. julifera, 

 F. V. M., MSS., non Benth. 



^4. julifera is described by Bentham in Hooker's London Journal Bat., i., 

 374. The type is from Rodd Bay, Port Curtis, Queensland. 



Bentham in B. Fl., ii., 405, keeps the two species apart, but unfortunately 

 Mueller only figures A. torulosa in his " Iconography." 



This is another pair of species which, as Bentham points out, are scarcely 

 to be separated except by the fruit, and therefore it is to be regretted that 

 opportunity was not taken of figuring A. julifera from the best material 

 available. 



It does not appear that A. julifera extends to the Northern 'Territory. 



A. torulosa is recorded from the Nicholson and the Roper, and I do not 

 know another authenticated Northern Territory locality. It extends into 

 Queensland. 



22. A.pachycarpa, F.v.M. {13Q). Sturt's Creek. 



In Mueller's paper Bentham places it under A. doratoxylon, but in B. FL, 

 ii., 409, he recognises its specific rank, and points out its affinity to A. 

 plectocarpa, A. Gunn. Mueller figures it in his " Iconography." 



23. A. conspersa, F. v. M. (140). 



Near the Roper and Limmen Bight Rivers. Bentham, in Mueller's paper, 

 points out its relationship to A. leptocarpa, A. Gunn. In B. FL, ii., 403, it 

 comes next to A. doratoxylon, A. Gunn. 



24. A. gonoclada, F. v. M. (140). 



Victoria River, also Arnhem's Land, Figured in '' Iconography." 



25. A. amentifera, F.v. 31. (141). Upper Victoria River. 



26. A. Wickhami, Benth. (141). Victoria River and Sturt's Creek. 

 Mueller described his " GuK of Carpentaria specimen No. 38," under the 



name A. calligera, and Bentham, in doubtfully referring it to A. Wickhami, 

 does not take his usual course of recording the synonym in B. FL, ii., 393. He 

 points out the variation in the species. 



27. A. ptychophylla, F. v. M. (142). Sturt's Creek. Still little known. 



28. A. umbellata, A. Gunn. (142). 



Type from Cleveland Bay and Cape FHnders, North Queensland, also 

 Bauer's " North Coast" which usually means Gulf of Carpentaria in this con- 

 nection. 



Bentham, in Mueller's paper, makes the latter's proposed name A. acra- 

 denia, a synonym. Mueller collected it at the Gulf of Carpentaria, Seven Emu 

 River, and sources of the Victoria River — Northern Territory localities. 



In the same paper Bentham pointed out that " Cunningham's specimen is 

 very bad," and that the specific name (umbellata) might perhaps be inappro- 

 priate, possibly an allusion to the habit that Mueller and other botanists 

 occasionally indulged in of changing specific names if they deemed them 

 inappropriate. 



In B. FL, ii., 394, under A. umhellata, Mueller's dcradenia specimens are 

 quoted, but the synonym is not mentioned, j^robably through an oversight.
