Narrative

Other associated species include Sporobolus mitchellii and Avena Fatua. Land use is on the edge of a lake. Drainage is also considered swamp. Wallaby grasses set back from lake but could be subject to flooding periodically. Grazing pressure light and sample size 10-100m2. Sample fruiting on non-irrigated site. Appears to be mostly A. caespitosa but may have some A. linkii mixed in (some lemma backs with hairs between main series and upper series exceeding twisted part of awn). Sample collected from further N along lake on a small peninsula. Lake flats on peninsula.
