Dendrobium is a diverse genus of orchids in the family Orchidaceae. It was established by Olof Swartz in 1799 and contains about 1,500 species. These species are found in diverse habitats throughout much of Asia, including the Himalayas, China, Japan, Thailand, Vietnam, Malaysia, Indonesia, Philippines, New Guinea, Australia, Solomon Islands, and New Zealand.

Description

Dendrobium species are highly variable in size and shape. They can be epiphytic, lithophytic, or terrestrial. The stems can be long and cane-like or short and bulbous. The leaves are usually arranged in two ranks and can be deciduous or evergreen. The flowers are also highly variable, ranging in size, shape, and color. They are often fragrant and can last from a few days to several weeks.

Habitat

Dendrobium orchids are found in a wide range of habitats, from lowland tropical forests to high-altitude mountainous regions. They can grow on trees, rocks, and in the ground. Some species are adapted to dry conditions, while others thrive in humid environments.

Cultivation

Dendrobium orchids are popular in horticulture due to their attractive flowers and diverse forms. They require specific growing conditions depending on the species. Generally, they need good air circulation, high humidity, and bright, indirect light. Watering and feeding requirements vary, with some species needing a dry rest period.

Uses

Some Dendrobium species are used in traditional medicine and herbalism. For example, Dendrobium nobile is used in Traditional Chinese Medicine for its purported health benefits. Additionally, Dendrobium orchids are popular in the floral industry and are often used in floral arrangements and corsages.

Conservation

Many Dendrobium species are threatened by habitat destruction and over-collection. Conservation efforts include habitat protection, cultivation in botanical gardens, and CITES regulations to control international trade.
