Bulbophyllum nematopodum, commonly known as the green cowl orchid,[2] is a species of epiphytic or lithophytic orchid that has small, flask-shaped pseudobulbs pressed against the surface on which it grows.

Description

Bulbophyllum nematopodum is an epiphytic or lithophytic herb that has crowded. flask-shaped pseudobulbs 12–20 mm (0.47–0.79 in) long, 7–9 mm (0.28–0.35 in) wide with a long narrow neck and pressed against the substrate. Each pseudobulb has an egg-shaped leaf 70–130 mm (3–5 in) long and 15–20 mm (0.59–0.79 in) wide on a stalk 20–30 mm (0.79–1.2 in). A single cream-coloured or pale green flower with red spots, 8–10 mm (0.31–0.39 in) long and 10–12 mm (0.39–0.47 in) wide is borne on a thread-like flowering stem 50–70 mm (2.0–2.8 in) long. The dorsal sepal is 6–8 mm (0.24–0.31 in) long, 3–4 mm (0.1–0.2 in) wide and the lateral sepals are 8–10 mm (0.31–0.39 in) long and 4–5 mm (0.16–0.20 in) wide. The petals are about 2 mm (0.08 in) long and 1 mm (0.04 in) wide. The labellum is pink to red, oblong, about 3 mm (0.1 in) long, 1.5 mm (0.06 in) wide, fleshy and curved. Flowering occurs from September to November.[2][3]

Taxonomy and naming

Bulbophyllum nematopodum was first formally described in 1873 by Ferdinand von Mueller who published the description in Fragmenta phytographiae Australiae from a specimen collected by John Dallachy near Rockingham Bay.[4][5] The specific epithet (nematopodum) is derived from the Ancient Greek words nema meaning "thread"[6]:798 and pous meaning “foot”.[6]:343

Distribution and habitat

The green cowl orchid grows on trees and rocks in rainforest where mists are common. It is found between the Cedar Bay National Park and the Paluma Range National Park.[2][3]

gollark: Oh dodecahedra, heavpoot's bid is STILL winning!
gollark: Don't we all?
gollark: When it inevitably fails to find a library somehow, you have to suffer through trying to make that work, and then it probably has some incomprehensible error on line 118812894 of the makefile.
gollark: I mean, you have a `./configure` script, which is as far as I know generated by YET ANOTHER program, which then either generates a makefile or breaks in random ways.
