Epiphytes, lithophytes or terrestrials very small to large, sympodial (shoots sometimes with continuous apical growth). Roots terete, glabrous or papillose-warty. Rhizomes short to elongated. Stems glabrous or with indument, cane-like or pseudobulb-like; when cane-like elongated, slender, fleshy or not, branching or not, long-lived, many-leaved, not covered or or partly entirely covered by leaf sheaths; when pseudobulb-like with 1 to many internodes, short and thick to much elongated and slender, with 1 to many leaves. Leaves arranged in two rows; base sheathing or not, sheath tubular or not, sometimes hairy (hairs blackish or white, yellow or red-brown); blade usually articulate and deciduous, conduplicate, dorsoventrally flattened, sometimes terete or laterally compressed, leathery or sometimes stiffly thin-textured, rarely hairy. Inflorescence lateral from the upper part of the stem or terminal, a raceme or carrying a single flower, 1-flowered or racemose, rarely paniculate, sometimes fasciculate. Flowers very small to large, resupinate or not, long-lived or ephemeral, often showy, sometimes fragrant. Median sepal free, rarely connate to the lateral sepals. Lateral sepals usually connate at the base, similar or dissimilar to the median sepal; mentum distinct, sometimes resembling a spur. Petals extremely variable in shape, entire, free, more or less similar to the median sepal, but in many species (e.g. most species of section Spatulata) very different in size and shape. Lip either adnate to the margins of the column foot, or rigidly attached to the apex of the column foot (breaks off when bent downwards), or flexibly attached (remains attached when bent downwards), or rarely hinged and highly mobile, usually not mobile, entire or lobed, with or without keels and/or callosities, not spurred but often forming a spur-like structure with the column foot. Column usually straight, without lateral wings, rarely with apical stelidia; column foot well-developed, usually longer than the column, often apically with a more or less shallow concave area; stigma concave, sometimes raised and callus-like; rostellum simple or sometimes 2-lobed, usually swollen into a cavity containing a sticky liquid which dries into a soft, putty-like substance; often with a downwards projecting, rigid, truncate or emarginate lamella between rostellum and stigma (the 'scraper'). Pedicel and ovary terete or winged, sometimes papillose or hairy. Fruit 1-locular, ellipsoid, oblong, obovoid to subglobose, sometimes winged or triangular in cross-section, usually opening along three longitudinal slits, sometimes with a single opening near the apex; without endocarpic elaters.


Sri Lanka, tropical continental Asia, Taiwan, Japan, Malaysia, Singapore, Brunei, the Philippines, Indonesia, Papua New Guinea, Australia, New Zealand, Pacific islands, east to Tahiti. About 1450 species; in New Guinea c. 560 species.

Epiphytes in lowland and montane forest. Some species are terrestrial in swampy places with sparse vegetation, in subalpine grassland, or on road banks, others grow on rocks and cliffs, but of the latter category most can also be found as epiphytes.

From a horticultural point of view Dendrobium is by far the most important orchid genus in New Guinea. Next to Bulbophyllum it is also one of the largest. The genus is divided into more than 40 sections, of which 22 occur in New Guinea. In New Guinea the showy species belong predominantly to the sections Latouria (e.g. Dendrobium spectabile (Blume) Miq.), Spatulata (e.g. Dendrobium lasianthera ), Phalaenanthe (Dendrobium bigibbum) and Calyptrochilus (e.g. Dendrobium smillieae F.Muell., Dendrobium lawesii F.Muell. and Dendrobium cuthbertsonii F.Muell.). The countless millions of dendrobiums produced by the cut flower industry in Thailand and Singapore, adorning every hotel and restaurant in Southeast Asia are hybrids of species originating from New Guinea and Australia, belonging to sections Phalaenanthe and Spatulata.

Systematics (IN PREPARATION)
Most of the sections of Dendrobium are quite distinct. Regrettably, in New Guinea the popular sections Pedilonum, Calyptrochilus and Oxyglossum, which contain several of the most charming orchids of New Guinea, have proved to be exceptions to this rule; we had to conclude that they can not be separated in a consistent way from section Calyptrochilus. Moreover, during the preparations for the database it was found that several sectional names in current use are synonyms of older, previously discarded names.

The following 22 sections and 4 subsections are known to occur in New Guinea (commonly used synonym names in brackets)

Aporum
