Phragmipedium hirtzii

A warm-growing slipper orchid from the lowland and foothill rivers of northern Ecuador and adjacent Colombia, with long, narrow leaves and branching spikes of greenish flowers. It grows on wet rocks near streams, so it needs warm, humid conditions and roots that never dry out.
