Ludisia (Lus.[2]) is a genus of orchids that was thought to contain just one species, Ludisia discolor, commonly referred to as jewel orchid. A second species, Ludisia ravanii, from the Philippines, was described in 2013.[3] Ludisia discolor is native to Southern China, Northeast India, Thailand, Vietnam, the Philippines, Malaysia, Indonesia and Myanmar,[4] and often cultivated.

Description

They are terrestrial orchids that in their natural setting would be found growing on the forest floor. They are known for their foliage, which is often velvety deep maroon with red veins that run parallel to the centre of the leaf.

Flowers are white with twisting yellow columns. Individual flowers are small but grow in clusters on upright stalks. Flowers in cultivation last a month or more.[5]

Cultivation

They need high humidity and warm temperatures with low to medium light, and they tolerate extremely low light levels.

Cultivars

Ludisia discolor has two notable cultivars:

  • L. discolor 'Alba', an albino variant, and
  • L. discolor 'Nigrescens', a mutation often referred to as "black velvet".

Hybrids

Hybrids of Ludisia with other orchid genera are placed in the following nothogenera:

Note that these hybrids are with other genera in the subtribe Goodyerinae, all commonly referred to as jewel orchids.

(The given references are to registered primary hybrids within each given nothogenus.)
