Sphaerostephanos spenceri

Description

Hairs on both sides of rachis dense, c. 0.3 mm long, with some less abundant 1 mm or more long.

Distribution

Asia-Tropical: Philippines (Philippines present), E. & S.E. Mindanao present
Malesia: Philippines (E. & S.E. Mindanao).

Notes

Christ failed to see the indusia and thus at first misled v.A.v.R. The short stipe and deeply lobed apical lamina appear to be distinctive and are shown by M. G. Price 2790 from Agusan del Sur Province, which is a rather small sterile plant differing from the type in scattered long hairs on the upper surface of costules and veins and in abundant glands on lower surface of costules and veins.
