"This large, densely caespitose species is distinguished by a flexuous, many-flowered raceme of large, bilabiate flowers that exceeds an acute, elliptical leaf. The dorsal sepal is five-veined; the partially connate, multiveined lateral sepals are antrorse to form an imperfect synsepal; the petals are thick, three-veined, and proportionately large, dominating the central apparatus. The lip is suborbicular and concave within a broadly rounded apex." Luer 2016
