"Vegetatively, this small species resembles other species, such as Stelis braccata Rchb.f. & Warsz. From these it is easily distinguished by three-veined petals and the distinctive lip. The lip is triangular in lateral view, with a two-humped bar uppermost, the dorsum being acutely deflexed from the anterior surface." Luer 2018
