Restrepia citrina is an orchid, close related to the pleurothallinids (subtribe Pleurothallidinae). The epithet 'citrina' (lemon-yellow) refers to the color of the lip. This rare epiphytic species is endemic to the cool, damp montane forests of the Eastern Cordillera of Colombia at altitudes of about 2,600 m. This tiny orchid lacks pseudobulbs. The erect, thick, leathery leaf is elliptic-ovate in shape. The aerial roots seem like fine hairs.
