Polystachya concreta

This is a pan tropical species and a very peculiar looking sympodial orchid because it looks like a terrestrial but is epiphytic. The individual growths can measure anywhere between 2 to 6 inches in height and are found growing in a reasonable amount of shade at about 800 to 1000 meters asl. The non fragrant flowers are very tiny, about 3 mm across with floral segments which are green in colour except for the lip which is white and occupies a superior position. The flowers are arranged on a terminal branched raceme and bloom from June through August.
