Note: The synonymy was proposed by Stewart & J. Norris (1981: 281, 283). The generic placement of P. caloglossoides is uncertain. Cystocarpic plants have not been reported from the type locality. On the basis of cystocarpic material from Mexico, Dawson (l.c.) transferred the species to Pterocladia, but abandoned this stance when dealing with the seaweeds of Peru (Dawson, Acleto, & Foldvik, 1964: 37–38).
