Taxonomy

Infraspecific variation. Several species are here included in P. lanceolata which have widely been regarded as separate. In the Malesian area the most common and best recognisable forms have been named as:
  • ‘adnascens’: Small plants, rather thick-leathery, with distinctly dimorphic fronds, the sterile ones often with rounded apex; rhizome scales short, mostly appressed. Throughout Malesia.
  • ‘varia’: Larger plants, thin-leathery, with wider, less distinctly dimorphic fronds, the sterile ones often with acute apex; rhizome scales large, spreading. Throughout Malesia. Although the original name is based on material that clearly represents the previous form, the most widely used interpretation is based on Blume’s plate (1829: plate 21), which clearly represents this form.
  • ‘dimorpha’: Relatively large plants, distinctly dimorphic, the sterile fronds often with rounded apex; rhizome scales often with a long entire filiform apex. Confined to New Guinea and surrounding islands.
  • ‘stellata’: Small plants, similar to ‘adnascens’, but with a very dense, conspicuously whitish indument. Restricted to New Guinea and surrounding islands; similar forms not always distinct from ‘adnascens’ sporadically occur in other areas.

Uses

Crushed and mixed with jintan itam and onion, then applied externally to relieve headache (Malaya); used to cure dysentery (Malaya).
