Phemeranthus sediformis

Phenology Flowering May–Jul.
Habitat Slopes, ledges, rocky soil
Elevation 1000-2000 m [3300-6600 ft]
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.
