Drynaria sparsisora

Distribution

Asia-Tropical: Lesser Sunda Is. present, Southeast Asia to Australia present
Southeast Asia to Australia. Throughout Malesia, but not known from the Lesser Sunda Islands.

Morphology

Juvenile foliage fronds often have a somewhat dilated frond base. The narrow, needle-like acumen of the rhizome scales often disappears from old scales, leaving older parts of the rhizome completely covered by characteristic, short, dark, appressed scales and scale-bases. Juvenile specimens tend to have longer, more narrowly subulate acumens, which also appear to be absent from older parts. Although the scales are usually quite different from those of D. quercifolia, occasionally some more intermediate forms occur. Juvenile plants or specimens without rhizome may be impossible to identify with certainty.

Uses

Medicine for eyes; rhizome applied to snake bites (Philippines), used for ‘rat scare-crow’ (Philippines). Salakans use it to be invisible to evil ghosts inhabiting Ficus species. Children use the base fronds as kites (Java).
