Glumicalyx nutans flowers

The about sessile flowers of Glumicalyx nutans grow in many-flowered, head-like spikes that nod. The inflorescence of this species is about top-shaped (turbinate). 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 to red on the inside, creamy white on the outside, as on the thin, cylindrical corolla tube. They spread here, often recurve. This may be an identification problem, so be wary of the identification made here.

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 (Springer, 2019: The role of pollinators as ecological drivers of diversification in the Drakensberg Mountain Centre endemic genus Glumicalyx (Scrophulariaceae, Limoselleae), University of the Witwatersrand; Manning, 2009; iNaturalist).
