Porroglossum hirtzii is from Ecuador (Alexander Hirtz is a well known German orchid collector in Ecuador). The plant is 4 cm tall and the leaves are a dark green with a lightly pebbled surface. The flowers spikes bear only one flower and are 10 cm long and tend to be pendant. The flowers are 1.5 cm long and have the typical hinged lip of this genus, a lip that swings up when the flower is disturbed by a pollinating insect, trapping the insect against the column of the flower. Two of the last three pictures show the flowers with the lip against the column.
