Dendrobium orchids are epiphytes; Growing on clinging to branches of trees. Roots orchids have thick roots covered with silver or white velamen. Which adsorb moisture and nutrients from the air such as Plalaenopsis

The Orchid Growth
Sympodial; Orchids are growing that grow sideways across the top of the pot. These orchids have a rhizome at the base usually put in horizontal, The bud at the base will begin growing anther rhizome. and then ,The rizome develops into a small plant or pseudobulb, and flower. When pseudobulbs have completely healthy, It will lose its leaves celled this pseudobulbs that "backbulb". It served store feed more years before it die.

Orchids sympodial-type such as Paphiopedilum Dendrobium Cattleya Oncidium Bulbophyllum Grammatophyllum etc.

Roots Dendrobium Orchids
Semi-aerial roots : Usually found on the rocks or the trees. Roots can be absorbed many water. it smaller aerial roots. Most roots inside the pot. But may have some roots emerge outside the pot. This orchid roots not like a tight pots or wet for too long, Which getting air not enough. this roots orchids such as Cattleya, Cymbidium, Dendrobium and Oncidium.

Epiphytes ; Growing on clinging to branches of trees. Roots orchids have thick roots covered with silver or white velamen. Which adsorb moisture and nutrients from the air such as Plalaenopsis Cattleya Dendrobium etc.

Terrestrials and semi-terrestrials; are thrive growing on/in the ground. Roots orchids frequently have hairy roots such as Paphiopedilum. Orchids don’t need a lot of fertilizer, either. As a matter of fact, most of these ground-plants can’t handle a lot of fertilizer. Terrestrial orchids share some characteristics with their greenhouse counterparts. These plants come in many shapes and size.

Lithophytes; Orchids that grow in or on rocks. Those that grow on rocks are also known as epipetric or epilithic plants. Lithophytes feed off nutrients from rain water and nearby decaying plants, including their own dead tissue. Chasmophytes grow in fissures in rocks where soil or organic matter has accumulated.

Dendrobium is a large genus of orchids. They contains about 1,200 species. The genus occurs in various habitats such as throughout much of south, east and southeast Asia, including China, Japan, India, the Philippines, Indonesia, Australia, New Guinea, Vietnam etc.

In 1799, Olof Swartz establish Dendrobium genus.

In 1981, Briegar reclassified all terete-leaved Dendrobiums from Australia and New Guinea into a new genus, Dockrillia. The Winika orchid from New Zealand was formerly D. cunninghamii, but has now been moved into a monotypic genus Winika

In 1989, Clements upgraded the D. speciosum complex into individual species;[2] similarly, the D. bigibbum complex (which contains the well-known Cooktown Orchid of Australia, D. phalaenopsis) has recently been split up. However, as an illustration of the current revisions in the taxonomy of Orchidaceae these 'splits' have now been reversed and the currently accepted species, natural nothospecies and synonyms are presented on Wikispecies Dendrobium.

Dendrobium species are either epiphytic or lithophytic. They have adapted to a wide variety of habitats.

Dendrobium is sympodial-type of orchids. They develop pseudobulbs, which in length from less than 1 centimetre to several metres long, looklike canes. Leaf bases form sheaths that completely envelope the stem.
