Gurania makoyana

Native from southeastern Mexico to Peru, this tropical forest climber has woolly young stems and simple tendrils. Leaves have heart-shaped bases, pointed tips and toothed edges, often divided into three to seven deep lobes. Juvenile leaves may be unlobed or only shallowly divided. Male flowers form rounded, hanging clusters with very long, narrow orange sepals and smaller, fleshy yellow petals. Female flowers occur separately in small groups. Cylindrical fruits contain numerous flattened seeds. Adult Heliconius butterflies collect pollen from its flowers, obtaining nutrients used for reproduction. Photographed in Colombia.
