Trees in forests; ca. 2000 m. S Yunnan (Mengzi) [Vietnam].
This species is very close to C.hookerianum, but the leaves are wide, the stamens are short, and there are not obvious reddish-brown longitudinal veins on the sepals and petals, which can be distinguished. However, the above characteristics are similar to those of C.iridioides, so some people think that this species may be a hybrid between it and C.iridioides. Since we have not taken the specimen, it is difficult to judge. The above description is excerpted fromDu Puy ＆ Cribb的《The Genus Cymbidium)。 |
