Distribution and Ecology

Occurs in CYP and NEQ, from Palmerston N.P. in NEQ north to Cape York in CYP (Booth et al, 2009). Altitudinal range uncertain but possibly mostly near sea level. Grows on margins of rainforest and amongst riparian and semi-deciduous vine forest on coarse sandy loams.

Natural History & Notes

This species is named for the large number of spikes in the inflorescence, a feature which distinguished it from closely related species such as Cyperus pedunculosus.
