Flowers: sepals deciduous, ovate, to 4 mm; petals white, sometimes tinged pink or pale yellow, obovate to suborbiculate, to 8 mm; stamens 15; stigma 1, subcapitate. Capsules subglobose, trigonous, to 4 mm. Seeds without arcuate ridges, 1 mm.
Phenology: Flowering May–Jul.
Habitat: Slopes, ledges, rocky soil
Elevation: 1000-2000 m
Discussion
Of conservation concern.
Phemeranthus sediformis is poorly known and merits further study in the field and better representation in herbaria. When its characters and their ranges of variation are better known, it may prove to be indistinct from P. spinescens.
