Kuhlhasseltia is a genus from the family of the orchid (Orchidaceae). It consists of three types of herbaceous plants that are native to East and Southeast Asia.

description

The species of the genus Kuhlhasseltia have an underground rhizome that continues above ground as a leafy stem axis. The leaves are asymmetrically oval to almost round, the base merges into a short petiole that is tubular around the stem axis. In Kuhlhasseltia javanica , the leaf color is blackish green on top and red on the underside.

The racemose inflorescence is terminal. The inflorescence axis is covered by a few bracts and is hairy. The lanceolate, ciliate bracts are about as long as the ovary and pedicel together. The ovary is twisted, it can be hairy. The flowers are resupinated . The two lateral sepals are larger than the upper sepal, they adhere to each other at their base and encompass the lower part of the lip . The lateral petals adhere to the upper petal. The lip is divided into three parts: the basal part, the hypochil, is fused with the edges of the column and forms a hemispherical to conical bulge. There are two elongated appendages in this bulge. In the very long middle part, the mesochil, the edges are turned inwards and provided with a weakly developed, smooth or toothed bar. The front part, the epichil, is entire or bilobed. The column is semicircular in cross-section, the oval stamen contains two club-shaped pollinia that hang directly on the small adhesive disc (Viscidium). The scar consists of two interconnected surfaces. The separating tissue between the stigma and the stamen (rostellum) is straight in the axis of the column and is divided into two at the end.

Occurrence

Kuhlhasseltia species are common in East and Southeast Asia, they are found in Taiwan, Borneo, Java and Sumatra. They settle at altitudes from 900 to 2000 meters. They grow in humus soil in shady forests.

Systematics and botanical history

Kuhlhasseltia is classified within the tribe Cranichideae in the subtribe Goodyerinae . According to Dressler, this can be further divided into two groups; Kuhlhasseltia is in the larger group with only one contiguous area of scarring. The genera Chamaegastrodia and Odontochilus are very similar . Vexillabium is a synonym of Kuhlhasseltia .

The genus Kuhlhasseltia was established in 1910 by Johannes Jacobus Smith . The name honors the German naturalist and zoologist Heinrich Kuhl (1797-1821) and the Dutch doctor and naturalist Johan Coenraad van Hasselt (1797-1823). Type species is Kuhlhasseltia javanica .

There are currently three types of Kuhlhasseltia :

Kuhlhasseltia gilesii Ormerod : It occurs in Sabah .
Kuhlhasseltia integra (Fukuy.) TCHsu & SWChung : It occurs in Taiwan.
Kuhlhasseltia javanica J.J.Sm. : It occurs in Sumatra, Borneo and Java.
