June 30th, 2012. We visited our favorite matelea vines – the Maroon (Matelea carolinensis) and Yellow (Matelea flavidula) Carolina Milkvines in Hancock County and then wandered along the roadside looking for other flowers. W spotted a vine with smallish leaves and even smaller flowers at the bottom of a steep, almost vertical drop-off beside the road. (W just likes to see if I’ll bite). It was very hot and I couldn’t quite see getting down the slope let alone up again. However, we spotted another, much-more-accessible plant a little further along the road.
The tip of a vine with several clusters of flowers. This plant would probably go unnoticed unless you’re walking along a road or trail.
A closer view of the leaves. This plant, a member of the family Apocyanaceae, has a milky, sticky sap.

Close up views of an individual flower from slightly different angles. The flower is only about one-quarter inch in diameter.
