Abstract
Abstract A taxonomic description, and the macroscopy and microscopy of the rhizome and leaf bases of Dryopteris ramosa (Hope) C. Chr. and D. chrysocoma (Christ) C. Chr. are given. Both the species compare very favourably in oleoresinous content and “crude filicin” with the official male fern. Because of their abundance in nature they could be commercially exploited. Like the official male fern, both the species possess schizogenous cavities in the ground tissue with internal glands. D. ramosa is devoid of sclerotic nests while a few of these are present in the other species both in the rhizome as well as in the leaf bases.
