DR. F. MUELLER ON AUSTRALIAN ACACIiE. 139 



86. Acacia oligoneura {Ferd. Mueller, MSS. — Acacia delibrata. 

 All. Cunn. ex Benth. in Hook. Land. Journ. of Bot. i. p. 374, var.?). 

 Glabra, ramulis gracilibus angulato-compressis, phyllodiis chartaceis 

 subsessilibus elongatis angusto-lanceolatis acuminatis longe in apicem 

 basinque angustatis leniter curvatis trinerviis reticulato-venosis basi 

 glanduligeris, nervis juxta basin cum margine inferiore confluentibus, 

 glandulis marginalibus nullis, spicis axillaribus solitariis vel fascicu- 

 latis brevibus cylindraceis glabris, pedunculis gracilibus, calyce laxo 



membranaceo dentato corolla ter breviore, leguminibus 



In terra Arnhem's Land prope MacAdam's Range, No. 96; et Vic- 

 toria River, No. 95. 

 Phyllodia pleraque 4-6" longa, semunciam lata. Spicee semunciales v. 

 paulo longiores. 



[The specimens Nos. 95 and 96 are in young seed, and Cunningham's 

 are out of flower with a loose fruit ; but as far as these materials admit 

 of identification, they appear to belong to the same species : the phyl- 

 lodia are, it is true, longer and not so coriaceous ; but so they are in some 

 of Cunningham's specimens. Dr. Mueller's specimen No. 91, from 

 Fitzmaurice River, is exactly hke one of Cunningham's, except with rather 

 more coriaceous phyllodia ; it is in good fruit, and the pod similar to 

 Cunningham's. The specimens Nos. 7^, 90 and 92 from Sturt's Creek, 

 No. 25 from Roper, No. 40 from Seven Emu River, and No. 93 from 

 Lower Victoria River, have still more coriaceous phyllodia, and, in the 

 case of the two last, considerably shorter ; but they probably all belong 

 to one species. — G. B.] 



87. Acacia torulosa, n. sp. (Acacia julifera, F. Muell. MSS., non 

 Benth.). Arborescens, ramulis superne angulatis, phyllodiis breviter 

 et crasse petiolatis elongate- v. lineari-falcatis oblique glanduloso- 

 apiculatis v. cuspidatis prominenter 3-5-nerviis crebre parallelo- 

 venosis glabris ima basi glanduligeris, spicis brevibus axillaribus 

 terminalibusque solitariis geminis ternisve densis breviter peduncu- 

 latis, calycis profunde partiti segmentis angusto-spathulatis ciliatis 

 puberulis corolla triente brevioribus, legumine flexuoso toruloso mar- 

 ginato acuminato stipitato inter semina valde contracto. 



Sandy banks of the Nicholson, No. 26. Roper River, No. 23. Gulf of 

 Carpentaria, No. 24. 



Frutex elatior. Phyllodia et spicee illis A. delihratce similia. Legumina 

 2-4" longa, matura non visa. 

 [This appears to me to be a good species ; the pod is diiferent from 



any one I am acquainted with in this section. It is not my A. julifera, 



which may perhaps be one of the numerous forms of A. delibrata.

88. Acacia doratoxylon {A. Cunn. in Field, N. S. Wales, p. 345 ? 

 — Acacia pachycarpa, n. sp., F. Muell, MSS.). Glabra, ramulis su- 

 perne angulatis, phyllodiis brevissime petiolatis lanceolato- v. elon-
