Trichanthera gigantea

This plant is a tree native from Panama to southern tropical America. It grows in wet tropical habitats and has four-sided stems and opposite, pointed leaves. Compact flower clusters develop at the branch tips. The tubular flowers have a brick-red interior and four projecting stamens with conspicuously hairy anthers. Its fruits are capsules that split into two valves. Photographed in the central Andes mountain range of Colombia.
