A large number of white, cup-shaped, resupinate flowers 2–2.5 mm (0.079–0.098 in) long and wide are arranged along a thin, wiry flowering stem 200–450 mm (7.9–18 in) long. The sepals are about 1.5 mm (0.059 in) long and 1–1.5 mm (0.039–0.059 in) wide the petals slightly shorter and narrower. The labellum is about 1.2 mm (0.047 in) long and wide and turned downwards. Flowering occurs between October and February. [2] [3] [4]

Taxonomy and naming

The native fan orchid was first formally described in 1834 by Achille Richard who gave it the name Oberonia micrantha and published the description in Voyage de la corvette l'Astrolabe: exécuté par ordre du roi, pendant les années 1826-1827-1828-1829. [5] [6] In 1859 John Lindley changed the name to Phreatia micrantha. [7] The specific epithet (micrantha) is derived from the Ancient Greek words mikros meaning "small" or "little" [8] :488 and anthos meaning "flower". [8] :338

Distribution and habitat

Phreatia micrantha usually grows on rainforest trees sometimes on rocks. It is most common on mossy branches over streams. It is found on the Bismarck Archipelago, New Guinea, the Solomon Islands, Queensland (Australia), Fiji, Niue, New Caledonia, Samoa, Santa Cruz Island, Tonga, Vanuatu, the Wallis and Futuna Islands and the Mariana Islands. In Queensland it occurs between the Iron Range and Tully River on the Cape York Peninsula. [1] [4] [9]
