Keywords:Flora, Wet Tropics, fern, diversity
AbstractThe Malesian species Hymenophyllum reinwardtii is reported as a new record for Australia. This distinctive filmy fern can be recognized by the undulate and dentate lamina margins, the undulate and dentate rachis wing, and the circular indusial flaps whose margins are usually irregularly and sparsely denticulate or rarely entire. The species was collected in the vicinity of the summit of Mt Finnigan in June 2017, and is currently known in Australia by this one gathering.
