Notes:Dendrobium uncipes is allied to Dendrobium aberrans and Dendrobium amphigenyum. It is approached in size by young plants of both, which like many Latouria species will flower when still quite small. In its flower structure it is closer to Dendrobium amphigenyum, differing in having narrower side-lobes to the lip and distinctively coloured flowers.
(after Cribb, 1983).

Cultivation: Intermediate growing epiphyte.
