118 DR. F. MUELLER ON AUSTRALIAN ACACLE. 
gumina pene cincinnata contorta affinitatem cum 4. 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 Müller 
describes them; they are broad at the base, with a narrow subulate 
_ point as long as the flower.—G. B.] 
5. Acacia obliqua, All. Cunn. ex Benth. in Hook. Lond, Journ. i. 334. 
Prope montes Buffalo Range. Ad sinum St. Vincentii alibique in 
colonia South Australia. 
Frutex pluripedalis, ramis зере arcuatis. Ramuli plurimi conspicue 
angulati. Calyx 5-partitus corolle dimidium subsequans, laciniis 
spathulato-linearibus. Legumina fuscescentia state fere nigrita 
tenui-coriacea insigniter eincinnato-spiralia stipitata enervia circiter 
H" lata. Semina subfusco-nigrescentia fere reniformia nitentia 2" 
longa bréviter pallide strophiolata. 
Variat glabra et pubescens.

Linnea, xxvi. p. 608, adnot.) ^ Arborescens, glaberrima, virens, 
ramulis gracilibus angulosis, stipulis perminutis subulatis v. oblite- 
ratis, phyllodiis parvis tenui-coriaccis oblique triangularibus v. trape-

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 pulcherrimus flexilis altitudinem 20' attinens. 
Cortez sordide fuscus levis. Rami sspe recumbentes. Ramuli 
elongati adscendentes. Phyllodia utplurimum 3-4'" rarius ad 6"

annotinorum descripti. Legumina bipollicaria v. breviora, 2’" lata. 
Semina sesquilineam metientia. 
Stirps quam maxime memorabilis, species triangulares, quibuscum 
phyllodiis convenit, cum quibusdam sectionis üninerviarum inflo- 
rescentia convenientium (e. g. A. vestita, A.  culiriformi, et A. sca- 
puliformi) conjungens. Anth. vere.
