Hydroglossum heterodoxum (Kunze) T.Moore
Hydroglossum spectabile Liebm.
Lygodictyon heterodoxum (Kunze) J.Sm.
Lygodium heterodoxum is a slender, evergreen, climbing fern with a short-creeping rhizome[
]. All species of the genus have an elongated climbing rachis (leaf stem) that has the capacity for indefinite growth, often reaching lengths of several metres. It twines around other plants for support, often climbing up from the shade into a sunny position[
The plant is harvested from the wild for local use of its stems, which are used in basketry.
Although we have found no reports of toxicity for this species, a number of ferns contain carcinogens so some caution is advisable[
Many ferns also contain thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase[

Scandent or trailing on trees, shrubs and herbs, in forests and damp thickets at elevations from sea level to 1,000 metres[
|Other Uses Rating||
The roots can be planted in a shady position, allowing the plant to climb up into the sun[
]. Prefers a neutral to slightly acid soil[
The petiole and lower parts of the rachis (leaf stem) are used in basket making[
]. They are considered to be better than 'mimbre,' the vining stem of Monstera or Philodendron, which is sold in the local markets[
Serpentine layering. An actively growing frond is pinned down onto the soil surface at each node, where it may root and shoot out as a new plant[
