Scientific name: Lemmaphyllum accedens

Lemmaphyllum accedens was an epiphytic fern (growing on another living plant). The leaf stem (stipe) was slender, 2–6 mm long, and winged to the base. The scales found at the base of the leaf stem were narrow, 1–3 mm long, and had margins with small 'hair-like' teeth. The sterile leaves were ovate to elliptic in shape, 2–4 cm long and roughly 1 cm wide, and papery. Fertile leaves (those producing spores) were slightly larger, 3–8 cm long, broadest at the base and tapering gradually to the tip. The spores of this species were measured at 55–72.5 micrometres long, and 40–50 micrometres wide (Bostock & Spokes 1998b).

Lemmaphyllum accedens was recorded once at Lake Eacham, near Atherton, north-eastern Queensland in 1910 (Bostock & Spokes 1998b).

Lemmaphyllum accedens is also known from the Malay Peninsula, the Phillipines, New Guinea and Polynesia (Bostock & Spokes 1998b).

Lemmaphyllum accedens was recorded growing in rainforest. No further habitat details are known (Bostock & Spokes 1998b).

Lemmaphyllum accedens reproduced by means of spores and possessed no flowers. The details of its reproductive mechanism and timing are unknown (Bostock & Spokes 1998b).

The reasons for the extinction of Lemmaphyllum accedens are unknown (Bostock & Spokes 1998b).

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.
