Scientific name: Hymenophyllum lobbii

Hymenophyllum lobbii was an epiphytic fern (growing on another living plant). The species had thread-like rhizomes with scattered hairs. The fronds (fern leaves) were approximately 2 cm long. The leaf stalks were slender, approximately 6 mm long, and unwinged. The leaves were divided, often fan-shaped, 6–13 mm long, and 4–7 mm wide. The leaf segments were less than 1 mm wide and sharply toothed. There were 1–2 spore capsules on the upper segments of the frond (Bostock & Spokes 1998).

Hymenophyllum lobbii was recorded once from the summit of Centre Peak, Mt Bellenden Ker, north-eastern Queensland in 1909–1910 (Bostock & Spokes 1998).

Hymenophyllum lobbii has been recorded in north-east Borneo (Bostock & Spokes 1998).

Hymenophyllum lobbii was recorded growing on tree trunks in tropical rainforest (Bostock & Spokes 1998).

As a member of the fern family, Hymenophyllum lobbii 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 lobbii are unknown (Bostock & Spokes 1998).

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.
