186 DR. F. MUELLER ON AUSTRALIAN ACACIA. 
nisve breviter pedunculatis, floribus parvis glabris, sepalis tenerrimis 
liberis oblongis corolla triente brevioribus, leguminibus 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 opaca 13-4" longa, i-$'" lata. Spice vix unciales. Legu- 
men circiter sesquipollicem longum, 1-12" latum. Semina desunt. 
A, aneure et ephedroidi propinqua. 
(A specimen of this species is amongst Cunningham's specimens of 
his A. zylocarpa, 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 
differently described by Dr. Mueller.—G. B.] 
76. ACACIA oRTHOCARPA (F. Muller, 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 transversim septatis. 
Ла plagis dumoso-rupestribus ad ortum fluvii M‘Arthur River, No. 4. 
Phyllodia longitudine inter 1} et 4" varia, circiter }'" crassa, sulcis 
duobus indistincte percursa. Legumina circiter bipollicaria 3-4" lata 
in basin sensim attenuata. 
Species A. gonocarpe propinqua. 
[Closely allied to A. xylocarpa Cunn., and A. pityoides F. Muell. 
vith the foliage of the latter, the fruit is precisely that of the 4. 
ylocarpa.—G.B. | 
77. ACACIA GONOCARPA, n. sp. Ramulis tenuibus compresso-angulatis 
junioribus ramulisque viscidis, phyllodiis angusto-linearibus elongatis 
uninerviis recurvo-apiculatis basi glanduligeris, spicis brevibus densis 
axillaribus geminig v. solitariis breviter pedunculatis glabris, sepalis 
linearibus liberis corolla 5-fida duplo brevioribus, legumine sublignoso 
ad suturas rectas contracto oblique septato, valvis dorso convexis 
utroque latere acute carinatis. 
In terra Arnhem’s Land juxta partem austro-occidentalem sinus Car- 
pentariæ in plagis rupestribus, No. 7. 
Frutex pluripedalis. Phyllodia pleraque 2-3" longa, circiter j'"' lata. 
Spice unciales v. breviores. Legumina 2-3" longa, fusca, ad suturas 
tantum 13" lata sed inter angulos dorsi 3'"' metientia, basi et apice 
sensim attenuata striolata. Semina desunt. 
Species quam maxime singularis ad quintam Juliferarum sectionem per- 
tinens, ad A. zylocarpam quoque approximans. 
(Those specimens which are in flower only, precisely resemble the 
flatter-leaved specimens of A. xylocarpa, Cunn. ;. but the pod, from Dr. 
Mueller's description, must be quite different.—G. B.]
