Dendrobium schneiderae

Dendrobium schneiderae, commonly known as the Eungella moon orchid or small moon orchid,[2]:378–379 is an epiphytic orchid in the family Orchidaceae and is endemic to eastern Australia. It has crowded pseudobulbs with two leaves on the tip of each and arching flowering stems with up to thirty five waxy, yellowish, cup-shaped flowers. It grows in open forest and rainforest.

Description

Dendrobium schneiderae is an epiphytic herb which forms small, dense clumps. It has crowded cone-shaped to egg-shaped pseudobulbs 15–40 mm (0.6–2 in) long and 10–20 mm (0.4–0.8 in) wide. Each pseudobulb has two narrow oblong, dark green leaves 40–100 mm (2–4 in) long, 8–13 mm (0.3–0.5 in) wide on top. The flowering racemes are 80–250 mm (3–10 in) long and bear between five and thirty five yellow to greenish yellow, waxy, cup-shaped flowers that are 6–9 mm (0.2–0.4 in) wide. The dorsal sepal is 4–7 mm (0.2–0.3 in) long and 3–4 mm (0.1–0.2 in) wide. The lateral sepals are 2–4 mm (0.08–0.2 in) long and 3–4 mm (0.1–0.2 in) wide and the petals are about 3 mm (0.1 in) long and 2 mm (0.08 in) wide. The labellum is curved and yellow, 6–8 mm (0.24–0.31 in) long, 4–5 mm (0.16–0.20 in) wide and has three lobes. The side lobes are red and relatively long compared to the short middle lobe, which has a fleshy plate in its centre. Flowering occurs from January to April.[2][3]

Taxonomy and naming

Dendrobium schneiderae was first formally described in 1886 by Frederick Manson Bailey and the description was published in Occasional Papers on the Queensland Flora.[4] The specific epithet (schneiderae) honours the collector of the type specimen, "Mrs H. Schneider, a lady who has been most successful in collecting and cultivating Queensland ferns and orchids".[5]

There are two varieties of this orchid:

  • Dendrobium schneiderae var. major, Rupp – the Eungella moon orchid, which has larger flowers and only occurs near Eungella in Queensland, where it grows on ironbark in open forest and palm trees in rainforest;[2]:378[6][7]
  • Dendrobium schneiderae var. schneiderae – the small moon orchid which has smaller flowers and is found between Gympie in Queensland and the Clarence River in New South Wales where it grows in well-lit places in rainforest.[2]:379[8]
gollark: I mean, the atmosphere isn't very dense.
gollark: It *might* be possible to make it somehow, but it wouldn't *weigh* the same as it somehow could on Earth.
gollark: That's not really valid in the context of the entire observable universe.
gollark: *Weight* is mass times acceleration from gravity. The acceleration from gravity is probably going to change wildly across the whole observable universe, but I guess you could sample it at various bits and average it. In any case, that average acceleration probably won't be at the Earth level of 10-ish m/s².
gollark: No it wouldn't.
