     Before year 2000 untraceable in culture. Four specimens was listed "officially", the plant which was used for the description, one photographed in Yunnan, a cultivated seedling which disappeared (E.U.), and a specimen perhaps still in culture in Japan. On the way of reappearance from Thailand from where photography illustrating this page is originating.
