''Dendrobium'' species are mostly [[Epiphyte|epiphytic]], or [[Lithophyte|lithophytic]] although a few species are [[Terrestrial plant|terrestrial]]. They are [[sympodial]] [[Herbaceous plant|herbs]] with cylindrical roots usually arising from the base of a [[pseudobulb]]. The pseudobulbs, when present, are hard, sometimes cane-like, cylindrical or cone-shaped and more or less covered with the bases of the leaves. There are from one to many leaves arranged in two ranks, the leaves varying in shape from linear to oblong, sometimes cylindrical but never channelled or grooved. They are usually much longer than wide and last for only a single season.<ref name="China" /><ref name="ONG" /><ref name="ANBG" />

Between one and a large number of [[Resupination|resupinate]] or non-resupinate flowers are arranged along an unbranched flowering stem and may be short or long-lived. The flowers may be white, green, yellow, or pink to purple, often with contrasting colours in the [[Labellum (botany)|labellum]]. The [[sepal]]s and [[petal]]s are usually free from and more or less similar to each other but markedly different from the labellum. The labellum is more or less egg-shaped, with the narrower end towards the base and flanks the [[Column (botany)|column]]. There is often a [[Labellum (botany)|callus]] consisting of narrow, parallel ridges, in the centre of the labellum.<ref name="China">{{cite web |last1=Zhu |first1=Guanghua |last2=Ji |first2=Zhanhe |last3=Wood |first3=Jeffrey J. |last4=Wood |first4=Howard P. |title=''Dendrobium'' (石斛属 shi hu shu) |url=http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=109553 |publisher=Flora of China |access-date=18 January 2019}}</ref><ref name="ONG">{{cite web |title=Genus ''Dendrobium'' |url=http://www.orchidsnewguinea.com/orchid-information/genus/genuscode/169 |publisher=Orchids of New Guinea |access-date=18 January 2019}}</ref><ref name="ANBG">{{cite web |title=''Dendrobium'' |url=https://www.anbg.gov.au/cpbr/cd-keys/RFKOrchids/key/rfkorchids/Media/Html/genera/Dendrobium.htm |publisher=Australian National Botanic Gardens |access-date=28 February 2021}}</ref>
