Phreatia listeri

Phreatia listeri is a species of epiphytic orchid. It is endemic to Christmas Island, an Australian territory in the north-eastern Indian Ocean. Its specific epithet honours British zoologist and plant collector Joseph Jackson Lister, who visited the island on HMS Egeria in 1887.[2]

Description

Phreatia listeri is a small, clump-forming epiphytic orchid. The long, thin leaves are 40–110 mm long and 2–5 mm wide. The 40–80 mm long inflorescence has many tiny, greenish-white flowers, only about 1 mm across. The orchid's lip is concave and contracted at the base. The seed capsule is 25 mm long.[2]

Distribution and habitat

Found only on Christmas Island, the orchid is common on rainforest trees growing on the plateau and the upper terraces of the island.[2]

Relationships

The orchid resembles both P. limenophylax Benth. from Norfolk Island, and P. minutiflora Lindl. from Borneo, but differs from them in its larger size and in the contracted lip.[2]
