The plant is tagged as Cleisostoma menghaiense. It eventually blooms, the flowers are not like genus Cleisostoma, but Stereochilus instead. There are only 7 different species or so in Stereochilus, but the flowers seem not belong to any of them. Is it possible be other genus? I was also told it was native to Menghai, Yunnan, China, and it was not hybrid. Can anyone help, please?
