Description

Bryobium dischorense is an epiphytic or lithophytic herb that forms dense clumps with oval shaped pseudobulbs 30–40 millimetres (1.2–1.6 in) long and 13–17 millimetres (0.51–0.67 in) wide covered with papery brown bracts when young. Each pseudobulb has a thin, but tough narrow oblong to egg-shaped leaf 70–135 millimetres (2.8–5.3 in) long and 30–35 millimetres (1.2–1.4 in) wide. Between four and eight cream-coloured or whitish, cup-shaped flowers with a few red spots, 6–8 millimetres (0.24–0.31 in) long and 5–6 millimetres (0.20–0.24 in) wide are arranged on a flowering stem 40–80 millimetres (1.6–3.1 in) long. The dorsal sepal is 6–7 millimetres (0.24–0.28 in) long and about 3 millimetres (0.12 in) wide, the lateral sepals a similar length but 5–6 millimetres (0.20–0.24 in) wide. The petals are 4–5 millimetres (0.16–0.20 in) long and about 2 millimetres (0.079 in) wide. The labellum is erect and curved, about 6 millimetres (0.24 in) long and 5 millimetres (0.20 in) wide with three lobes. The side lobes are large and erect and the middle lobe is short and turns downwards. Flowering occurs from October to December. [2] [3] [4]

Taxonomy and naming

The spotted urchin orchid was first formally described in 1912 by Rudolf Schlechter who gave it the name Eria dischorensis and published the description in Repertorium Specierum Novarum Regni Vegetabilis Beihefte. [1] [5] [6] In 2002 Mark Clements and David Jones changed the name to Bryobium dischorense. [7] The specific epithet (dischorense) refers to the type location, which Schlechter referred to as the Dischore Range, now known as the Bowutu Range. [8] The ending -ense being a Latin suffix meaning "denoting place", "locality" or "country". [9]

Distribution and habitat

Bryobium dischorense usually grows on rainforest trees. It is found in New Guinea and in the Whitfield Range in Queensland. [2] [3]

<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.
