Scientific name

Dendrobium (from Greek  δένδρον dendron , tree 'and βίος bios , life') is an extensive genus from the family of orchids (Orchidaceae), which is about 1,600 mainly tropical species covers. The genus was established in 1799 by the Swedish botanist Olof Peter Swartz . Dendrobium is also the name of a genus of beetles.

Way of life and occurrence

Dendrobia live mainly epiphytically , especially on trees, occasionally also lithophytically (i.e. on rocks). They colonize different habitats on the Southeast Asian mainland, the Philippines , Borneo , Australia , New Guinea and New Zealand . They have adapted there to a wide variety of habitats, ranging from the high elevations of the Himalayas to tropical lowland rainforests, and even encompassing the arid climate of inland Australia.


The representatives of the genus Dendrobium have a sympodial growth. The club-, spindle- or tube-like pseudobulbs differ greatly in size. The smallest representatives of the genus have shoots of only a few centimeters, while the shoots of the large species can be more than 100 cm long. The mostly oval leaves are alternate. The inflorescences appear both at the edges and at the tips of the previous year's pseudobulbs and are often racemose. It is characterized by a chin formation below the ovary , so that the lateral sepals are often wrong.


A list of the almost 1600 recognized species can be found in R. Govaerts.

Hybrid of Dendrobium nobile

Dendrobia are often cultivated as ornamental plants. There are numerous varieties and hybrids that are derived from two species in particular: Dendrobium nobile , which is also suitable for the cooler window sill and winter rest period, as well as Dendrobium bigibbum with a higher need for warmth and without a pronounced rest period.

In addition, dendrobias are also used in Chinese folk medicine, for example to strengthen the intestinal tract or to combat high fever.

Dendrobium sp. is able to remove xylene and toluene from indoor air to some extent .
