Rhizome short. Pseudobulbs clustered, usually cane like, fleshy, usually much elongated (up to 5 m tall in some species), sometimes short and ovoid (and then with few semiterete, grooved leaves),, with limited apical growth, with many internodes, rather fleshy; the very base swollen; apical part with several- to many leaves. Leaves glabrous, usually coriaceous; leaf sheath tubular. Inflorescences lateral on the upper part of the stem or subterminal, racemose, elongate, erect or arching, few- to many-flowered. Flowers medium-sized to large, resupinate, long-lived, often showy. Sepals not connate, often twisted; mentum usually with an abruptly narrowed, tubular, spur-like apex. Petals usually distinctly longer than the sepals, often spirally twisted. Lip not mobile on the top of the column foot, forming a narrow conical spur-like structure, abruptly widened above the spur, 3-lobed; bas with lamellate, keels which are often abruptly raised on the midlobe.

Species of Dendrobium section Spatulata are often called antelope dendrobiums, because many have erect, twisted petals that are usually longer than the sepals, resembling two horns. With their large flowers, often produced in generous to large quantities (at least under optimal conditions) these are among the showiest orchids of New Guinea, and therefore of high horticultural importance. Especially the large flowered species are used in hybridisation programs but these are not organised systematically and do not produce hybrids of standard quality and not in large numbers. In spite of their attractivity they are not very common in cultivation in temperate areas, because many species can become very large and require high temperature and much light.
Dendrobium section Spatulata is clearly related to sect. Phalaenanthe, as demonstrated by the existence of numerous hybrids involving both sections.
