Description

This slipper orchid was only discovered as recently as 1998 on an expedition to China (2). It is a striking terrestrial herb with large oblong leaves, which are found lying along the ground; they are a glossy dark green colour, distinctly spotted with black (2). This orchid bears large creamy white flowers atop a single flower stalk (or inflorescence). The petals curve inwards and both these and the lip are heavily marked with maroon spots (2).

Range

In the wild this species is known only from the southeast of the province of Yunnan, in southern China (2). Several plants have also been grown in cultivation (2).

Biology

Very little is known about this newly discovered orchid, new leafy shoots were observed to be emerging in early May with flowering taking place later in the same month (2). This species occurs further south than any other member of the genus (2).

Threats

This orchid is widely available commercially in Japan, Taiwan and Europe (2).

Conservation

Further research is needed to investigate the range of this newly described species in the wild, especially whether it occurs in neighbouring Vietnam (2).

Herb: A small, non-woody, seed bearing plant in which all the aerial parts die back at the end of each growing season.
Inflorescence: A group of flowers on a single stem. (See http://www.rbgkew.org.uk/ksheets/pdfs/flower.pdf for a fact sheet on flower structure)
