Tresses ( Goodyera ) is the name of a genus of plants from the family of orchids (Orchidaceae). The approximately 100 species are predominantly distributed in the northern hemisphere and have a focus on diversity in Southeast Asia . Some of these relatively small-flowered species are popular with orchid growers as ornamental plants because of their attractive leaves .

Vegetative characteristics

In Goodyera TYPES concerns perennial herbaceous plants . They have rhizomes , from which both sterile shoots with leaf rosettes and fertile shoots, usually creeping upwards at the base, branch off and end in inflorescences . Many species form runners .

The oval or lanceolate leaves have a short stalk. Usually the leaf epidermis along the main and transverse nerves is significantly lighter than the rest of the blue-green leaf surface. The upper sides of the leaves therefore usually show a high-contrast mesh pattern. The stem leaves are heaped at the base or greatly reduced.

Generative characteristics

The one-sided or slightly twisted, spike-like inflorescence consists of an unbranched axis on which unsporn, small, white-green flowers sit; the plants are reminiscent of species of the genus Spiranthes . The hermaphrodite flowers are threefold. The flowers have simple cup-like nectaries , the pollinia are sessile, the tip of the labellum is beak-shaped. The remaining five bracts form a small helmet.

Name declaration

The British botanist Robert Brown chose the scientific genus name Goodyera in honor of John Goodyer (1592–1664), who was an outstanding English plant connoisseur, botanist and plant collector of the 17th century.

In English, this genus, like the representatives of the genus Spiranthes , is referred to as ladies' tresses (“ladies curls, corkscrew curls”). This name alludes to the slightly twisted inflorescences. In America, the plants of the genus hot Goodyera rattlesnake plantain ( "Rattlesnake plantain"), because the rosettes on the one hand are similar to those of the plantain ( Plantago major ), on the other hand, the mesh pattern reminiscent of the leaf surfaces to a snake skin . It is said that compresses made from the leaves of the North American Goodyera species were also used to treat snakebites in the past .

The genus Goodyera was in 1813 by Robert Brown in William Townsend Aiton : Hortus Kewensis; or, a Catalog of the Plants Cultivated in the Royal Botanic Garden at Kew. London , 2nd edition, Volume 5, S, 197-198 prepared.

The genus Goodyera belongs to the Unterertribus Goodyerinae from the tribe Cranichideae in the subfamily Orchidoideae within the family Orchidaceae .

The genus Goodyera is pantropical and circumboreal . Of the 100 or so species, around 60 are found in Southeast Asia . There are about 29 in China and Taiwan, 12 of them only there. There is only one species on the European continent , the circumboreal creeping net leaf ( Goodyera repens ). The large-leaved net leaf ( Goodyera macrophylla ) is endemic to Madeira . Of 18 New World species, only four are found in North America . The other eight species grow in East Africa and on the islands of the Indian Ocean ( Madagascar , Réunion , Seychelles ).

The following species are included in the genus Goodyera :
