The sepals are ovate and thick, the petals are transversely oblong and the lip is elliptical, subacute and shallow. Centrally it is thickened with a narrow longitudinal glenion and basally it is densely pubescent adjacent to the shaft of the column which is also densely, shortly pubescent." Luer 2009
