Scientific Name: Phreatia limenophylax

Common Name: Norfolk Island Phreatia

This species has been confused with P. crassiuscula, a north Queensland taxon. Bentham described it under the name P. limenophylax in 1879, and P. crassiuscula was incorrectly used on the Norfolk Island three cent postage stamp issued in 1985 (Green 1994).

Norfolk Island Phreatia is a small, tufted, epiphytic orchid 3–6 cm high, with 2–3 cm long inflorescence of many tiny greenish-white flowers. There are four to six fleshy leaves with a grooved upper edge. The leaves are 20–60 mm long and 2–4 mm wide (DEH 2003b; Green 1994).

Norfolk Island Phreatia is endemic to Norfolk Island where it is very rare, and has been recorded from Anson Bay (DEH 2003b; Green 1994). A reference to it being a 'fairly common epiphyte' was based on confusion with Phreatia paleata, a species which also occurs on Norfolk Island (Green 1994).

In 2003, there were five mature plants surviving in the wild (DEH 2003b; TSSC 2003o).

Norfolk Island Phreatia occurs within the Norfolk Island National Park (Director of National Parks 2008).

This species lives on tree branches (DEH 2003b).

Norfolk Island has a sub-tropical climate (BoM 2008).

Principles relevant to the conservation of Norfolk Island Phreatia can be found in the Norfolk Island National Park Management Plan (Director of National Parks 2008). There is a draft National recovery plan in preparation for this species.

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.
