nisve breviter pedunculatis, floribus parvis glabris, sepalis tenerrimis 

 liberis oblongis corolla triente brevioribus, leguininibus linearibus 

 flexuosis pallidis chartaceis inter semina leviter contractis aveniis. 

 In virgultis Brigalow Scrub, a fluvio Gilbert usque ad flumen Suttor, 



No. 6. Ad rivum Sturt's Creek, No. 5. 

 Phyllodia opacal2-4" longa, 3^— |"' lata. Spices vix unciales. hegu- 



men circiter sesquipollicem longum, 1-1^'" latum. Semina desimt. 

 A. aneurcB et ephedroidi propinquae. 



[A specimen of this species is amongst Cunningham's specimens of 

 his A. xylocarpa, which it closely resembles ; but the phyllodia are not 

 broader than thick, and the corollas appear more membranous, project- 

 ing less in the young spike. The foliage is precisely that of the follow- 

 ing species {A. orthocarpa) ; but the pod, which I have not seen, is 

 dilFerently described by Dr. Mueller. — G. B.] 



76. Acacia orthocarpa (F. MuUer, MS.). Glabra, ramulis teretius- 

 culis, phyllodiis filiformibus estriatis oblique et obtuse apiculatis, 

 spicis axillaribus subgeminis pedunculatis, leguminibus lignescentibus 

 lanceolato-linearibus rectis acutis margine obtusis longitudinaliter 

 venosis intus oblique transversira septatis. 



In plagis dumoso-rupestribus ad ortura fluvii M'Arthur River, No. 4. 



Phyllodia longitudine inter 1^ et 4" varia, circiter ^"' crassa, sulcis 

 duobus indistincte percursa. Legumina circiter bipoUicaria 3-4'" lata 

 in basin sensim attenuata. 



Species A. gonocarpce propinqua. 



[Closely allied to A. xylocarpa Cunn., and A. pityoides F. Muell. 



With the foliage of the latter, the fruit is precisely that of the A. 



xylocarpa. — G.B.] 



77- Acacia gonocarpa, n. sp. Ramulis tenuibus compresso-angulatis 

 junioribus ramuhsque viscidis, phyllodiis angusto-linearibus elongatis 

 uninerviis recurvo-apiculatis basi glanduligeris, spicis brevibus densis 

 axillaribus geminis v. solitariis breviter pedunculatis glabris, sepaUs 

 linearibus liberis corolla 5-fida duplo brevioribus, legumine suhlignoso 

 ad suturas rectas contracto oblique septato, valvis dorso convexis 

 utroque latere acute carinatis. 



In terra Arnhera's Land juxta partem austro-occidentalem sinus Car- 

 pentarise in plagis rupestribus. No. 7. 



Frutex pluripedalis. Phyllodia pleraque 2-3" longa, circiter ^"' lata. 

 Spic<s unciales v. breviores. Legumina 2-3" longa, fusca, ad suturas 

 tantum li'" lata sed inter angulos dorsi 3"' metientia, basi et apice 

 sensim attenuata striolata. Semina desunt. 



Species quam maxime singularis ad quintam Juliferarura sectionem per- 

 tinens, ad A. xylocarpam quoque approximans. 

 [Those specimens which are in flower only, precisely resemble the 



flatter-leaved specimens of ^4. xylocarpa, Cunn.; but the pod, from Dr. 



Mueller's description, must be quite different. — G. B.]
