Glumicalyx nutans flowers

The about sessile flowers of Glumicalyx nutans grow in many-flowered, head-like spikes that nod. The yellow-green, hairy calyces with pointed tips covering the backs of the corolla tubes are glume-like, giving the genus its name. A glume is the bract or leaf-like structure below spikelets in the inflorescences of grasses or the flowers of sedges.

The five oblong petal lobes are brownish orange on the inside, creamy white on the outside, as on the thin, cylindrical corolla tube. The four stamens in two pairs of different length have pale anthers that protrude from the flower mouth, as does the style that is even longer (Manning, 2009; iNaturalist).
