Selliguea soridens

Distribution

Asia-Tropical:, Borneo present; Maluku (Maluku present); Sulawesi (Sulawesi present)
Malesia: Borneo, Sulawesi, Moluccas.

Notes

— 1. Selliguea soridens can be confused with S. stenophylla. The following characters most easily distinguish the two species:
stenophyllussoridens
scales bicolorous, dentate concolorous, entire
margin not notched notched
fertile spike narrowednot narrowed
soriwell within marginclose to margin
mouth of soral cup rimmedwide


A few specimens from Borneo are more or less intermediate (Chew et al. 854, 1157), they have a monomorphic fronds and sori with a distinctly rimmed mouth, in these characters corresponding to S. stenophylla, but to S. soridens in other characters. From either species they differ in the rhizome without sclerenchyma strands.
2. Some specimens have a wide fertile area and sori located on protruding marginal teeth. A few specimens show some intergradation to Selliguea stenophylla.
