N.S.W.: Side of Bluff Mtn, Warrumbungle Ra., 23 Jan. 1975, R.H.Harden (NSW).


Regarded as a member of the ‘Acacia microbotrya group’ on account of its long, reddish funicle which encircles the seeds. Very closely related to A. flocktoniae. Acacia linearifolia and A. macnuttiana are similar to A. forsythii in having long, linear phyllodes and racemose inflorescences, but both relatives have short funicles which do not encircle the seeds.
