Species Description - (leaves deep green above, pale green beneath, dull on both surfaces; pedicels and hypanthium coral-red; corolla green in bud, red as it begins to open, and purple with age). (small shrubs 1 m., epiphytic or terrestrial; pedicels and calyx deep coral-red; corolla green, carnose, very hard when open; plants later seen in shade, with nearly white flowers).

Discussion:
Psammisia sclerantha is another of the species with pinnatinerved leaves, characterized by having the calyx-limb and distal part of its corolla extraordinarily thick in texture and its anthers with broad, spurred connectives and very short, slender tubules. From P. sodiroi Hoer. and the other species of this alliance except P. oreogenes Sleumer, the new species differs in its merely denticulate (rather than conspicuously lobed) calyx-limb. Psammisia oreogenes, however, has comparatively short-petioled leaves and a differently proportioned calyx (the limb being shorter and thinner) and anthers.
