Thelasis ( Inglês )

fornecido por wikipedia EN

Thelasis, commonly known as fly orchids,[2] is a genus of flowering plants from the orchid family, Orchidaceae. Plants in this genus are usually epiphytes, sometimes lithophytes or rarely terrestrials. Some species have pseudobulbs with up to three leaves, whilst others have several leaves in two ranks. A large number of small, white or greenish yellow flowers are borne on a thin, arching flowering stem. There are about thirty species, distributed from tropical and subtropical Asia to the southwest Pacific.

Description

Plants in the genus Thelasis are mostly epiphytic or lithophytic, rarely terrestrial sympodial herbs with thin roots. They often have small pseudobulbs with up to three leaves but sometimes have flattened stems with several leaves in two ranks. Many small white or greenish yellow flowers are crowded on a thin arching flowering stem. The flowers are resupinate, tube-shaped near the base with sepals and petals free from and similar to each other although with the petals usually shorter and narrower. The labellum is stiffly attached to the base of the column and lacks lobes.[2][3][4][5]

Taxonomy and naming

The genus Thelasis was first formally described in 1825 by Carl Ludwig Blume who published the description in Bijdragen tot de flora van Nederlandsch Indië .[6][7] The name Thelasis is derived from the Ancient Greek word thelazo meaning "suckle" or "nurse",[8] possibly referring to a small nipple-like structure on the column.[5]

Thelasis ( Neerlandês; Flamengo )

fornecido por wikipedia NL

Thelasis is een geslacht met 26 soorten orchideeën uit de onderfamilie Epidendroideae.

Het zijn voornamelijk epifytische en lithofytische orchideeën uit de regenwouden van Zuidoost-Azië, Nieuw-Guinea en noordelijk Australië.

Naamgeving en etymologie

  • Synoniem: Oxyanthera Brogn. (1834); Rhynchophreatia (Schltr.) Schltr.

De botanische naam Thelasis is afkomstig van het Oudgriekse θηλή, thēlē (tepel), waarschijnlijk naar de vorm van de bloemen of van de pseudobulben.

Kenmerken

Thelasis-soorten zijn overwegend epifytische planten met verticaal samengedrukte pseudobulben, dikwijls bedekt door de bladscheden. De bloemstengel draagt meestal maar één lijnvormig, leerachtig tot vlezig blad. De bloeiwijze is een laterale aar met een lange bloemsteel, en vele dicht op elkaar gepakte kleine bloempjes die zelden ver opengaan.

De bloemlip is eenlobbig, breed aan de basis waar ze versmolten is met de basis van het gynostemium, en versmallend naar de top. Er zijn acht pollinia in twee groepen van vier, door een lang en slank stipum verbonden met een verlengd viscidium.

Habitat en verspreiding

Thelasis-soorten groeien op bomen en bemoste rotsen in de warme regenwouden van Zuidoost-Azië, van India tot China en zuidelijk tot Nieuw-Guinea en noordelijk Australië

Taxonomie

Het geslacht telt 26 soorten. Sommige taxonomen reken ook de leden van het geslacht Oxyanthera hierbij. De typesoort is Thelasis obtusa.
