Lip shortly clawed, strongly 3-lobed, 6.3 by 12.7 mm; side-lobes spreading, narrowly elliptic, subacute; midlobe bifid with a blunt mucro, the sinus, with each lobule resembling a smaller side-lobe; callus fleshy, 3-ridged, half length of lip.

Dendrobium uncipes J.J.Sm. is allied to Dendrobium aberrans Schltr. and Dendrobium amphigenyum Ridl.. 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.
