The female flowers of Cannomois parviflora appear as a few spikelets per culm, closely spaced and alternating at nodes near the culm tip. The about spindle-shaped spikelets are partly covered by narrow, pointed spathes and bony bracts.
The six perianth segments of each floret in a spikelet are small and glassy or hyaline. Each floret has two feathery styles, longer than the ovary that has one locule.
The fruit is a shiny, brown nut, flattened on the side facing the culm (Dorrat-Haaksma and Linder, 2012; Bond and Goldblatt, 1984; iNaturalist).
