Notes. Known
widely as A. hiemalis in Australia. At one time Vickery considered
naming this a distinct species A. propinqua, but then placed it within
her concept of A. hiemalis. Her concept of the species was wider than
that used here, including some specimens now placed with A. bettyae. It
differs from A. scabra in having the spikelets more clustered towars the
end of the branches, the lower whorl of branches being more divided and shorter
spikelets (Jacobs 2001).

Endemic. In N.S.W., Vic. and Qld.
Often in damp or swampy areas. Flowers Nov.-Apr.
