Subjective junior synonym of Gualtieria Agassiz, 1847
Remarks Elbassyony (2005) recognized this to be close to Gualtieria, differentiating it on the basis that the lower portion of the anterior petals below the peripetalous fasciole is V-shaped, not parallel. However, this feature is variable and a similar morphology can be found in specimens of Gaultieria (e.g. see G. grossouvrei Lambert, 1912) .
