Synonyms.
— This is a species which has given rise to a surprising amount of confusion. It has been more or less confused with at least three species.
(1) Acacia Lunata, F.v.M. non Sieb., "F. Mueller refers it (A. prominens) to A. lunata, describing the pod very accurately; but that is not the fruit of the true A. lunata, which has always the seed lying close to the upper suture, not in the centre of the pod." (Bentham in B.Fl. ii, 371.) Mueller referred some indubitable specimens of A. prominens (A. Cunn.) to A. lunata (Sieb.), and Bentham followed him. These have caused great confusion in herbaria. In Part XLIV I shall figure A. lunata, Sieb., and, I trust, clear up all difficulty in this particular matter.
In Mueller's "Key to the System of Victorian Plants," i (1887-1888) and ii (1885), A. prominens will be found synonymised under A. lunata.
(2.) Acacia fimbriata, A. Cunn. (see B.Fl. ii, 371), has also been confused with A. prominens as a synonym. I trust that the figures and descriptions of A. fimbriata in Part XLII of this work will render confusion impossible in the future.
(3.) A. linifolia, Willd., var. prominens, F.v.M. Herb. In Mueller's "Second Census" (1889) it does not appear, but it was included by Mueller under A. linifolia, Willd., as a variety (e.g., prominens). Bentham also contributed to this view by saying (B.FI. ii, 371): "This species (prominens) may prove to be a broadleaved variety of linifolia." And, again, under A. Iinifolia, he speaks of "The broadleaved forms of this species, with the margins less ciliated (really A. fimbriata, A. Cunn., as I have shown in Part XLII of this work. J.H.M.), or not perceptibly so, connect it with the following, A. prominens."
I trust that the illustrations and notes concerning A. Iinifolia, Willd., given in Part XLlI, will render confusion with A. linifolia impossible in the future.
