Notes

Blume distinguished var. B. with more rigid fronds and sori confluent; I have not seen the type, and consider the distinctions not good. v.A.v.R. described var. sumatrana (Handb. 220) from a small plant with gradually reduced lower pinnae; it might represent another species (type not found). Christ gave a brief description of the Sarasin specimen from Celebes cited under Aspidium multijugum, referring to Nephrodium multijugum and ascribing the name to Wallich, but Wallich included specimens of three dilferent species under his n. 348 and it is not clear to which of them Baker's description applies, though certainly not to P. callosa. I have not seen the Warburg specimens also cited by Christ.
