This was once considered to have no joints at the base of the leaf ( Chen and Liu, 2003 ), but after careful observation, there are indeed less obvious joints. Recently, some plants were obtained from Rongxian County, southern Guangxi. They are similar to this species in body and flower morphology, but they have obvious pseudobulbs and bloom only once a year. We believe that it is a geographical variation of C.omei, because some individuals of C.omei have been cultivated in Shenzhen for several years, and the pseudobulbs have also become obvious, and only once a year. Of course, further observation is needed. |
