1. We have selected the subspecific name of pallens because stipe, rhachis, and costae are paler than those of B. melanocaulon subsp. melanocaulon. Blechnum melanocaulon subsp. melanocaulon has darkly pigmented stipe and rhachis (and some­times costae), at least on the abaxial surface.
2. In the living state the mature fronds of B. melanocaulon subsp. pallens are very dark green, shiny, fleshy and brittle and the new fronds brilliant deep pink.
