i found these in the mountains one time. they look like some kind of convolvulaceae. i only grabbed a picture of the fruit though. fruits were round and about 3cm diameter. memory doesnt serve too well, but the leaves were divided more, not the common heart leaves, more like passionfruit style. grew low along the ground and on lower plants. in taiwan if needed i will try and go back and gets some pictures if the road wasnt destroyed. mmm photos on another computer i will upload tonight.
