Description

Delicate, percurrent, much branched plants; leaf-bearing internodes 2-5 cm long, orange brown, terete and ca. 0.1 cm thick below when leaf-bearing, expanding somewhat and slightly keeled above; basal cataphylls 1-5. Leaf blade thin, narrowly elliptical, mostly to 6 x 1.5 cm, apex rounded, with long, slenderly tapering base; venation inconspicuous, pinnate, often with 2 strong basal veins. Dioecious; occasional bisexual plant and possibly some unisexual inflorescences.Inflorescence peduncle mostly simple but sometimes with to 2 pairs of sterile cataphylls, 0.1-0.3 cm long; fertile internodes 2 or 3. Male inflorescence to 1.5 cm long; flowers to 18 per fertile bract, 3-seriate. Female inflorescence to 2 cm long in fruit; flowers mostly 3 per fertile bract. Fruit globose, 0.3 cm in diameter, perianth segments closed.

Notes

Superficially somewhat reminiscent of a slender form of P. quadrangulare, but mostly dioecious, and with very different cataphyll characteristics. Also similar to slender plants of P. obtusissimum in general aspect but, in contrast to that species, mostly dioecious and with simple peduncles. Young leaves characteristically tend to be reddish-translucent at least when dry.

Plant sexuality

Dioecious; occasional bisexual plant and possibly some unisexual inflorescences.32
