This is another shy to flower vine. It took a me long time for me to identify it. This leafless green vine is not a hoya, a dischidia or a cynanchum. I first saw it twining over scrub on limestone cliffs at Raleigh beach, Krabi. The impression then was dodder (Cuscuta sp), a parasitic vine commonly found on mangrove and coastal vegetation. But it is too green and has a milky sap, and that helps me to narrow down to milk-weed family (Asclepiadaceae). Again i found it in Halong Bay, Vietnam... twining over Euphorbia antiquorum and other Dracaena. With luck it was in flower and i'm now able to narrow it down to Sarcostemma brevistigma. Unlike Hoya and dischidia, it would never really find a place in collections for lack of flowers and its vining habit. Well it is bless with robustness and a very wide distribution range from India, Nepal, Myanmar and all the way to Thailand, Vietnam and Southern China and is unlikely to face extinction.
