Neuwiedia is a genus from the family of the orchid (Orchidaceae). It consists of eight types of herbaceous plants thatare native totropical Southeast Asia .

description

The species of the genus Neuwiedia do not form a rhizome , the roots arise from the shoot both underground and above ground. They are thin, sometimes hairy, surrounded by velamen radicum .

The rising, unbranched shoots carry the leaves in a loose rosette. The leaves are linear to narrow oval shaped. The leaf base runs in a wedge shape into an indistinct petiole that encompasses the shoot and completely covers it. The leaves are pleated (plicate) along the veins .

The racemose , upright inflorescence appears terminal, it usually does not rise above the leaves. The leaves go up into smaller bracts , the shoot can be covered with hair and glandular hair in this area. The bracts are quite large. The short flower stalk is thickened by the oval ovary clearly separated. The flowers are resupinated and sit slightly crooked on the ovary. The petals are free, slightly curved and white, cream or yellow in color. The sepals are fleshy in texture, the petals thinner. A specialization of a petal as a lip is hardly noticeable, this petal is slightly wider than the others. The column arises from the stamens and styles that have grown together on the ground . There are three fertile stamens . The resulting capsule fruit is oval shaped with three longitudinal ribs.

Occurrence

Neuwiedia is common in tropical Southeast Asia. The northern limit of distribution runs through southern China and Thailand. To the southeast, the area extends over India , Indonesia, the Philippines to New Guinea, the Solomon Islands and Vanuatu . Neuwiedia species occur from the seashore up to an altitude of about 1300 meters. Neuwiedia veratrifolia and Neuwiedia Zollingeri are the species with the greatest distribution.

The locations are mostly in the shade of evergreen, moist forests.
