This photo nicely illustrates the interesting red-tipped underside of the leaves, as well as the characteristic pentadenia-section flowers. Other photos further illustrate the flowers, the spectacular large pinkish/lavender berries and an arresting combination of leaves, flowers and berries. The red tips of the underside of the leaves likely serve to attract pollinating humminbirds to the flowers, as do the red "windowpanes" characteristic of some other species.
The individual flowers are quite hairy and produce lots of pollen, as can be seen here.
Also known as Pentadenia orientandina.
