Finding a gurania in bloom in a world of green is about as exciting as running into a flashy passion fruit flower. I discovered this one only two days ago close to the old roundhouse, which was destroyed a few years ago by a falling rubber tree. The plant is a vine belonging to the cucumber family, Cucurbitaceae. There are different species but the ones I've seen seem to be the same. In reality, I've never seen many of them, maybe an average of two or three a year. This flower was only off the ground 12 inches or so but I've seen them high up in the trees. An anonymous reader of the blog remarked that this may be G. eriantha.
