Geodorum ( Inglês )

fornecido por wikipedia EN

Geodorum, commonly known as shepherds' crooks[2] or 地宝兰属 (di bao lan shu),[3] is a genus of eight species of flowering plants in the orchid family, Orchidaceae. They are deciduous, terrestrial herbs with underground pseudobulbs, broad, pleated leaves and small to medium-sized, tube-shaped or bell-shaped flowers on a flowering stem with a drooping end. Species in this genus are found in southern Japan, tropical Asia, Australia and islands of the southwest Pacific Ocean.

Description

Orchids in the genus Geodorum are deciduous, terrestrial herbs with pseudobulbs underground but close to the surface. There are several pleated leaves emerging from the pseudobulb, the largest at the top. Each leaf has a stalk which wraps around those below it. The flower stalk also emerges from the pseudobulb and bears a few to many bell-shaped or tubular flowers. The sepals and petals are similar in size and shape and do not spread widely apart from each other, so that the flowers do not open widely. The portion of the flowering stem carrying flowers droops, so that although the flowers are non-resupinate, the labellum is the lowest part of the flower. The labellum has three lobes but lacks the spur or pouch of orchids in the similar genus Eulophia.[2][3][4]

Taxonomy and naming

The first formal description of Geodorum appeared in The Botanist's Repository for New, and Rare Plants edited by Henry Cranke Andrews.[1][5] There is a description and an illustration of Geodorum citrinum, now known as Geodorum terrestre.[6] The illustration was the work of Andrews but although not recognised in the book, the description is believed to be the work of George Jackson.[7] The name Geodorum is derived from the Ancient Greek words ge meaning "earth"[8]: 290  and doron meaning "leaf",[8]: 277  apparently referring to the terrestrial habit of orchids in this genus.[4]

Species

Species accepted by the World Checklist of Selected Plant Families as of October 2018 are:[1]

Distribution

Orchids in this genus are found in India, Southeast Asia including Malaysia, the Philippines and Indonesia. There are two species endemic to China and others occur in New Guinea and New Caledonia. One species (Geodorum terrestre) occurs in Western Australia, the Northern Territory, Queensland and New South Wales.[2][3]

Geodorum ( Neerlandês; Flamengo )

fornecido por wikipedia NL

Geodorum is een geslacht van orchideeën uit de onderfamilie Epidendroideae.

Het zijn terrestrische planten met ondergrondse pseudobulben en een dichtbloemige, overhangende bloemtros, die voorkomen in tropische streken van India, Zuidoost-Azië, Japan, China, Australië en Polynesië.

Naamgeving en etymologie

  • Synoniemen: Otandra Salisb. (1812), Cistella Blume (1825), Ortmannia Opiz (1834)

De botanische naam Geodorum is afkomstig van het Griekse gèa (aarde), verwijzend naar de terrestrische levenswijze van deze planten.

Kenmerken

Geodorum zijn middelgrote terrestrische planten met gelede, bolvormige of cilindrische ondergronds groeiende pseudobulben op een korte rizoom, die gewoonlijk in groepen samengroeien. De bladeren onspringen uit de onderste geleding van de pseudobulb, zijn gebundeld, waaiervormig geplaatst, naar boven toe groter wordend, elliptisch tot lancetvormig, en gesteeld. De overhangende bloemstengel ontstaat naast de bladeren uit de onderste geleding van de pseudobulb, en draagt een eindstandige, knotsvormige, dichtbloemige tros met tientallen bloemen.

De bloemen zijn klein, wasachtig, welriekend, zelden volledig geopend, en niet-geresupineerd, doch omdat de tros ondersteboven hangt is de lip toch onderaan geplaatst. De kelk- en kroonbladen zijn gelijkvormig, de kelkbladen aan hun basis gefuseerd, de kroonbladen vrijstaand. De bloemlip is ongedeeld of vaag drielobbig, aan de basis zakvormig en gefuseerd met het gynostemium, met een geribde of van uitstulpingen voorziene callus. Het gynostemium is kort, met een korte voet, een eindstandige helmknop en twee wasachtige pollinia die door een dik stipum verbonden zijn met een groot viscidium.

Soorten

Het geslacht omvat dertien soorten. De typesoort is Geodorum citrinum.
