Description:
Rhizome spindle-shaped to linear, 10-60 mm long; roots fleshy, horizontaly interconnected; persistent leaf bases present at the top of the rhizome. Leaves 1 to 2, held at 70-80% from the horizontal. Petiole up to 25-70 mm long, 40–60% of its length subterranean. Sterile lamina 20-60 × 7-29 mm, grey or glaucus green, narrowly elliptic to oblong lanceolate, length:width ratio 1.4–4.5:1 (5-10.5:1 in var. angustifolium), apex pointed, mucronate, occasionally rounded, base wedge-shaped, texture rather fleshy, venation obscured in live material; fertile spike 40–100 mm long, with 12–30 pairs of sporangia.
Notes: O. polyphyllum is easy to recognise by the cluster of dried leaf petioles at the top of the rhizome. Recently 2 var. have been distinguished: var. polymorpha (width:length ratio 1:1.4-4.5) and var. angustifolium (width:length ratio 1:5-10.5)
Derivation of specific name: polyphyllum: with many leaves
