Taxonomy

2. Polypodium soromanes H. Christ is probably a hybrid between this species and another, unknown, species. It has simple, narrow, more or less strap-shaped fronds, often with some irregular lobes at the base, and large, sometimes elongated sori close to the midrib. 1 This species is closely related to, and often confused with M. scolopendria. The dried fronds are mostly dark brown or blackish, whereas in M. scolopendria they are usually yellowish green. In M. papuanum the sori are in one row parallel to the costa, but sometimes in two rows, in M. scolopendria in one to several. There are several collections intermediate between the two species, but they grow together and generally behave as good species.
