Description

Schoenorchis micrantha is a small epiphytic herb that forms small, tangled clumps. It has thin, curved, twisted, branched stems 30–150 mm (1–6 in) long and many thick, curved fleshy, linear leaves 30–60 mm (1.2–2.4 in) long and 2.5 mm (0.1 in) wide. Between five and thirty densely crowded, tube-shaped to bell-shaped white flowers, about 2 mm (0.079 in) long and 1.5 mm (0.059 in) wide are arranged on a flowering stem 10–30 mm (0.4–1 in) long. The sepals are about 2 mm (0.079 in) long and 1 mm (0.039 in) wide whilst the petals are about 2 mm (0.079 in) long and 1.5 mm (0.059 in) wide. The labellum is about 2.5 mm (0.1 in) long with three lobes. The side lobes are short and erect and the middle lobe is short with a short spur. Flowering occurs between April and July.[2][3][4]

Taxonomy and naming

Schoenorchis micrantha was first formally described in 1825 by Carl Ludwig Blume from an unpublished description by Caspar Reinwardt and the description was published in Bijdragen tot de flora van Nederlandsch Indië.[1][5] The specific epithet (micrantha) is derived from the Ancient Greek words mikros meaning "small" or "little"[6]:488 and anthos meaning "flower".[6]:338

Distribution and habitat

The tangled flea orchid grows on mangroves and rainforest trees in humid, well lit places. It is found in Thailand, Vietnam, Borneo, Java, the Lesser Sunda Islands, Peninsular Malaysia, the Philippines, Sumatra, New Guinea, the Solomon Islands, Queensland, Fiji, New Caledonia, Samoa and Vanuatu. In Queensland it is found between the Iron Range and the Tully River.[1][2][4]

gollark: It was actually on caddy for quite a while, but v2 annoyed me, so I went back to nginx.
gollark: I have about 500 lines of horribly entangled configuration files driving this, despite the original design of osmarks.net (formerly osmarks.tk) calling for it to mostly be a static website.
gollark: Now, the diagram says "nginx". Nginx is also an important part of this setup. It is a reverse proxy allowing me to run all this slightly crazy stuff on one IP, and encrypt with "HTTPS" apiotechnology.
gollark: It also got a HTTP endpoint, available at https://radio.osmarks.net/random-stuff/current-song, which dumps the status etc. information in JSON for the frontend to read.
gollark: So this gained a loop polling MPD - remember, it has a client-server model, so other stuff can communicate with it. Use of MPD turned out to be a good design decision!
