Utricularia minutissima

Description

Terrestrial. Inflorescence erect, 3-12 cm long, glabrous or with a few short septate hairs on the peduncle; Ovary ovoid, style short, stigma lower lip orbicular, upper lip much smaller, deltoid. Capsule obliquely oblong-ovoid, 1.5-2 mm long, membranous in texture, translucent, dehiscing by a longitudinal ventral slit which is marginally scarcely thickened. Seeds few globose, 0.17-0.2 mm long, testa smooth, reticulate, reticulations relatively large, ± isodiametric.

Distribution

Asia-Temperate, Asia-Tropical: Borneo present; India present; Malaya present; New Guinea present; Philippines (Philippines present); Sumatera (Sumatera present), Australasia: Queensland (Queensland present), Japan present
India to China and Japan, Indo-China, Malesia, and Australia (Northern Territory and Queensland); in Malesia: Sumatra, Malaya, Borneo, Philippines, and New Guinea.

Notes

This species is very variable in overall and in flower size, and the degree to which the lower corolla lip is lobed. The peduncle varies from quite glabrous to sparsely hairy but the hairs when present do not extend to the calyx as in U. hirta. The 'rigid patent black bristly hairs' mentioned by PRAIN and often present are in fact not hairs but fungal growths.
