- Diagnosis
- Pendulous staminate inflorescences, rachis
with stellate trichomes. Florets singular, stalked. Perianth
cyathiform, short and widely open, sometimes campanulate;
incised to middle or lower third, forming triangular
to lanceolate lobes with irregular serrate margins. Outer
perianth surface and margin glabrous, only very rarely
with 1 solitary trichome. Each floret with a central trichome
tuft, composed of solitary trichomes. Stamens
numerous, 8 – 13 per floret, filaments short and mostly
covered by perianth. Anthers elliptic to narrowly elliptic
with obtuse apex, basifixed. Some florets subtended by
singular, linear, slender bract terminating in acute apex;
bracts mostly glabrous, with sparse solitary trichomes.
Pollen weakly microverrucate, perforate.
