Description

Trachoma papuanum is an epiphytic or lithophytic herb that forms clumps with a few thin roots and branching stems 30–60 millimetres (1.2–2.4 in) long. There are between three and six thick, fleshy, elliptic to egg-shaped, dark green leaves 50–80 millimetres (2.0–3.1 in) long, about 20 millimetres (0.79 in) wide and arranged in two ranks. A large number of short-lived, pale yellow, cup-shaped, resupinate flowers 2–3 millimetres (0.079–0.12 in) long and 3–4 millimetres (0.12–0.16 in) wide are arranged on a flowering stem 5–15 millimetres (0.20–0.59 in) long. Up to four flowers are open at the same time. The sepals are about 5 millimetres (0.20 in) long and 3 millimetres (0.12 in) wide, the petals about 4 millimetres (0.16 in) long and 1 millimetre (0.039 in) wide. The labellum is about 4 millimetres (0.16 in) long and 5 millimetres (0.20 in) wide with three short lobes and a spur about 1.5 millimetres (0.059 in) long. Flowering occurs from February to April.

Taxonomy and naming

The yellow spectral orchid was first formally described in 1913 by Rudolf Schlechter who gave it the name Saccolabium papuanum and published the description in Repertorium Specierum Novarum Regni Vegetabilis Beihefte. [1] [6] [7] In 1989 Mark Clements, Jeffrey Wood and David Jones changed the name to Trachoma pupuanum. The specific epithet (papuanum) refers to the type location, the ending -anum a Latin suffix meaning "pertaining to" or "belonging to". [8]

Distribution and habitat

Trachoma papuanum grows on rainforest trees often on branches over streams and in other humid places. It is found in New Guinea, the Solomon Islands, Fiji, Niue, New Caledonia, Vanuatu, the Cook Islands, the Society Islands, Tubuai and Queensland where it grows between Cairns and Innisfail.

<i>Cymbidium</i> Genus of flowering plants in the orchid family Orchidaceae

Cymbidium, commonly known as boat orchids, is a genus of evergreen flowering plants in the orchid family Orchidaceae. Orchids in this genus are epiphytic, lithophytic, terrestrial or rarely leafless saprophytic herbs usually with pseudobulbs. There are usually between three and twelve leaves arranged in two ranks on each pseudobulb or shoot and lasting for several years. From one to a large number of flowers are arranged on an unbranched flowering stem arising from the base of the pseudobulb. The sepals and petals are all free from and similar to each other. The labellum is significantly different from the other petals and the sepals and has three lobes. There are about fifty-five species and sixteen further natural hybrids occurring in the wild from tropical and subtropical Asia to Australia. Cymbidiums are well known in horticulture and many cultivars have been developed.
