We have a thousand other views sent in of every other aspect of the this plant if we need them. I chose not to post all of them.

Basionym: Cymbidium quinquelobum Z. J. Liu & S. C.
Chen, Acta Bot. Yunnan. 28: 13. 2006.
Inflorescence arching or subpendulous, 7–12-flowered.
Sepals 65–80 × 23–26 mm. Lip obscurely 5-lobed. Column 42–
48 mm.
? Trees in broad-leaved forests; ca. 1500 m. SE Yunnan (Maguan).
This variety grows in the same region as the typical variety. Its 5-
lobed lip is probably an abnormality rather than a typical feature.
Cymbidium wenshanense, award 20103146, has been confirmed to be Cymbidium wenshanense by SITF(June 2010).
