Tropicals & Tender Perennials: Hoya, or not a Hoya?, 1 by tropicbreeze

While trekking in PNG I was keeping an eye out for Hoyas. Trouble was that none were flowering. Quite a few likely contenders had a milky sap, but I'm 'reliably informed' that not all small vines that have a milky sap are Hoyas. Anyway, this is a photo of one contender that had a very nice looking leaf, even if no flowers at the time. It was at a moderate altitude so I'd guess an intermediate grower. Of course, it might turn out it's not a Hoya at all, I'm no expert.
