Scientific name: Hymenophyllum whitei

Hymenophyllum whitei was an epiphytic fern (growing on another living plant). The species had rhizomes (horizontal stems embedded in the host plant's tissue) that were thread-like, branched, smooth, or with minute hair-like appendages. The fronds (fern leaves) were 1.2–2.7 cm long. The leaf stems were slender, not winged, 1–5 mm long, and scattered along the rhizome. The pale bluish-green leaves were linear-oblong or ovate-oblong in shape, and deeply divided into 5–10 smooth, rounded segments, each 2–3 mm wide. Most segments were forked. The spore capsules were borne singly at the tips of the leaf lobes (Bostock & Spokes 1998).

Hymenophyllum whitei was known from Thornton Peak in north-eastern Queensland (Bostock & Spokes 1998).

Hymenophyllum whitei was found growing in tropical rainforest at approximately 1000 m altitude (Bostock & Spokes 1998).

As a member of the fern group Hymenophyllum whitei reproduced by means of spores and did not have flowers. No details of its reproductive mechanism or timing were recorded (Bostock & Spokes 1998).

The reasons for the extinction of Hymenophyllum whitei are unknown.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
