118 DE. F. MUELLER ON AUSTRALIAN ACACIA. 



gumina psene cincinnata contorta affinitatem cum A. obliqua et A. 



acinacea demonstrant. 



[Dr. Mueller's specimens were so very imperfect, that I was unable 

 to detect any specific difference between them and A. sublunata. The 

 branches in Bauer's specimen are not pungent ; but they are almost 

 as stiff as in Mueller's, and they may not unlikely become pungent. 

 The bracts, however, in Bauer's plant certainly are not such as Miiller 

 describes them; they are broad at the base, with a narrow subulate 

 point as long as the flower. — G. B.] 



5. Acacia obliqua, AH. Cunn. ex Bent h. in Hook. Lotid. Journ. i. 334. 

 Prope raontes Buffalo Range. Ad sinum St. Vincentii alibique in 



colonia South Australia. 



Frutex pluripedalis, ramis ssepe arcuatis. Ramuli plurimi conspicue 

 angulati. Calyx 5-partitus corollae dimidium subsequans, laciniis 

 spathulato-linearibus. Legumina fuscescentia setate fere nigrita 

 tenui-coriacea insigniter cincinnato-spiralia stipitata enervia circiter 

 1^'" lata. Semina subfusco-nigrescentia fere reniformia nitentia 2'" 

 longa breviter pallide strophiolata. 



Variat glabra et pubescens, 



6. Acacia pravissima {Ferd. Mueller, First Gen. Report; Benth. in 

 hinncea, xxvi. p. 608, adnot.). Arborescens, glaberrima, virens, 

 ramulis gracilibus angulosis, stipulis perminutis subulatis v. oblite- 

 ratis, phyllodiis parvis tenui-coriaceis oblique triangularibus v. trape- 

 zoideis mucronulatis opacis imperfecte binerviis venosis supra basin 

 glandulam gerentibus, angulo superiore rotundato-obtuso, racemis 

 polycephalis phyllodia longe superantibus summis paniculam consti- 

 tuentibus, bracteis minutis cymbiformi-deltoideis, capitulis pauci- 

 floris, bracteolis rhomboideis fimbriatis, calyce obtuse 5-dentato 

 petalis fere triplo breviore, leguminibus compressis linearibus tenui- 

 coriaceis obtusis breviter stipitatis fuscescentibus enerviis margine 

 repandis intus continuis, seminibus nigritis compresso-ovatis minutim 

 livide strophiolatis vix areoligeris. 



In vallibus et ad torrentium ripas tractus Buffalo Range et secus partes 

 superiores fl. Snowy River. 



Arbuscula v. frutex pulcherriraus flexilis altitudinem 20' attinens. 

 Cortex sordide fuscus laevis. Rami ssepe recumbentes. Ramuli 

 elongati adscendentes. Phyllodia utplurimum 3-4'" rarius ad 6'" 

 longa et lata, sessilia, nervis antice evanescentibus, supero tenuiore. 

 Racemi jam ante anthesin 1-2-unciales. Flores tantum e residuis 

 aunotinorum descripti. Legumina bipollicaria v. breviora, 2'" lata. 

 Semina sesquilineam metientia. 



Stirps quam maxime memorabihs, species triangulares, quibuscum 

 phyllodiis convenit, cum quibusdara sectionis uninerviarum inflo- 

 rescentia convenientium (e. g. A. vestita, A. cultriformi, et A. sca- 

 pnliformi) conjungens. Anth. vere.
