Note: In the absence of any original material for the name, Renz’s designation of 1057.4 (LINN) as “type” can be accepted as a neotypification under Art. 9.8. It pre-dates a different choice as neotype (an Oeder illustration) made by Baumann & al. (in Mitteilungsbl. Arbeitskr. Heim. Orchid. Baden-Württemberg 21: 443, Abb. 4. 1989).
