Description

Orchids in the genus Peristylis are terrestrial, perennial, deciduous, sympodial herbs with paired fleshy tubers and thread-like, unbranched roots. The stems are upright and unbranched. The leaves are arranged in a rosette at the base of the plants or near the centre of the stem. The flowers are resupinate, usually small, often crowded, white, green or yellowish and usually only last a few days. The dorsal sepal and petals overlap to form a hood over the column. The labellum has a spur and usually three lobes which may be short or long and threadlike. The distinguishing feature of the genus is the presence of two club-shaped projections on the stigma. In many respects, plants in this genus are similar to those in Habenaria, only differing in the structure of the column.[2][5]

Taxonomy and naming

The genus Peristylus was first formally described in 1825 by Carl Ludwig Blume and the description was published in Bijdragen tot de flora van Nederlandsch Indië .[1][6] The genus name is derived from the Ancient Greek words peri meaning "around" or "near"[7]:102 and stylos meaning "pillar" or "post",[7]:608 referring to the arms on each side of the column.[5]

Distribution

Orchids in the genus Peristylus are found in Japan, China, Mongolia, India, Indochina, Indonesia, Philippines, Malaysia, the Philippines, Indonesia, New Guinea, Polynesia and Australia.[1][5][8][9][10][11]

As of March 2018[update], the World Checklist of Selected Plant Families accepted the following species:[12]
