Galeola is a genus from the family of the orchid (Orchidaceae). It contains four to six species of herbaceous plants that are native to Southeast Asia.

description

The species of the genus Galeola are terrestrial, herbaceous climbing plants. They are leafless and feed on mykoheterotroph . There is an extensive rhizome and root system underground , mostly in half-rotten wood. Above ground, the reddish-brown shoot climbs with adherent roots that form at each node . The leaves are reduced to small scales.

The paniculate inflorescences contain numerous resupinated , yellow or brown, wide open, fleshy flowers . The inflorescence axis is hairy red-brown, as are the sepals . These are elongated-oval and not grown together. The petals are similarly shaped, but not as fleshy. The lip is entire and rounded, the edge is curled and ciliate. The blade of the lip is hairy and has a callus at the base. The column is curved, thickened to a club-shaped front, at the front end with two lateral appendages. The stamen is two-chambered, the two pollinia are granular and again divided into two. The capsule fruit is long and narrow, it contains numerous winged seeds. The wing runs around the seed and is irregularly shaped. The seeds of Galeola are spread by the wind.

distribution

Galeola is common in back India , the Philippines, the Indonesian islands to New Guinea. Galeola humblotii is native to the Comoros . Galeola nudifolia is the most widespread . The plants are found in forest clearings and require larger accumulations of dead wood.

Systematics and botanical history

Galeola is classified within the subfamily Vanilloideae in the tribe Vanilleae . The closest related genera are Cyrtosia , Erythrorchis and Pseudovanilla .

Galeola was first described by João de Loureiro in 1790 . The name Galeola comes from the Greek galeole , "little helmet", and describes the helmet-shaped end of the column. The type species is Galeola nudifolia , numerous species were described under the name Galeola until Garay divided them into several genera in 1986.

The following species are included in the genus Galeola :

Galeola cathcartii Hook.f. : It occurs from Sikkim to northern Thailand.
Galeola faberi Rolfe (possiblybelongingto Cyrtosia ): It occurs from Nepal to southern and central China and Sumatra .
Galeola falconeri Hook.f. : It occurs from the Himalayas to northern Indochina, in southeastern China and in Taiwan. It is also called Cyrtosia falconeri (Hook.f.) Aver. placed in the genus Cyrtosia .
Galeola humblotii Rchb.f. : It occurs on Grande Comore and Madagascar.
Galeola lindleyana (Hook.f. & Thomson) Rchb.f. : It occurs from the Himalayas to China, on Taiwan and in northern Sumatra. It is also called Cyrtosia lindleyana Hook.f. & Thomson placed in the genus Cyrtosia .
