Acacia cyperophylla F.v.M. 
The Red Mulga. 
(Family LEGUMINOS^E : MIMOS^E.) 
Botanical description. Genu?, Acacia. (See Part XV, p. 103.) 
Botanical description. Specie?, A. cypcropliylla, F. Mucll. Herb, (iu B.F1. ii ; 400, 
18C4). 
Tall, with curly bark and dark wood, branchlets terete. 
Phyllodia linear-subulate with a fine, usually curved point, 6 to 10 inches long, terete or very 
slightly compressed, striate with numerous exceedingly fine parallel nerves only visible under 
a lens, hoary with a very minute loose pubescence. 
Spikes sessile or nearly so, oblong, not inch long. 
Flowers mostly 5-merous or G-merous. 
Calyx turbinate, about half as long as the corolla, at first shortly toothed but often dividing nearly 
to the base. 
Petals smooth, glabrous. 
Pod unknown. 
In the courss of time some confusion has arisen in regard to this species, Mueller 
himself sometimes forgetting what he had originally described under that name, 
oftoncst substituting A. Burkittii F.v.M. for it. 
I accordingly requested Professor Ewart to kindly favour me with all the 
material in the Melbourne Herbarium attributed to A. cyperophylla, which he promptly 
did. None of the material received was authentic, except the Leichhardt and Gregory 
specimens. 
The Gregory specimen, which is evidently the type, bears the following very 
old label, in Mueller's handwriting : 
" Acacia cyperophylla, F.v.M. inedit 
' A aneura affinis (sepalis diversa). . . Stony ground, Cooper's Creek. 
" Tall stem with curly bark and dark wood." 
It is in flower only, and is the comparatively coarse twig in the middle of the 
plate of Acacia cyperophylla, as depicted by Mueller in his " Iconography of Australian 
Acacias."
