Peristylus Last updated May 25, 2025 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 name Peristylus is derived from the Greek words peri meaning 'around', and stylos 'column', referring to the arms on each side of the column. [ 5]
