Primary axis very short, non-floriferous, with a few small leaves. 
Thallus filamentous, exogenously branched alternately right and left, 
with no root cap. Secondary axes at forks of thallus, erect, to 2-4 cm. 
high, covered below Avhen fully grown with the scars of fallen leaves, 
somewhat dorsiventral in structure. Leaves to 30 cm. long, distichous, 
subulate, sheathing, simple. Flowers in axils of dithecous leaves or 
otherwise terminal, erect. Spathe about 3-10 mm., splitting irregular- 
ly at the tip. Stamens usually 2, equalling ovary and stigmas. Ovary 
not winged. Capsule 2-3 mm. long, elliptical, 8-ribbed, anisolobous, 
on pedicel 3-20 mm. long, whose cortical tissues fall during the 
ripening of the fruit.

P. subulatus Mavœliœ ; Fruit pedicels 3-10 mm., erect. 
Ceylon ; in the Mafia weli-ganga and its tributaries, from

The Ceylon specimens from Hakinda show a tendency 
to group themselves into a large and a small form, and 
the specimens are also small at the higher localities.
