Huebner 226 was originally designated as the type of 
Hybochilus Huebneri, but it was destroyed during the 
Second World War. ‘To the best of my knowledge, the 
two collections in the Ames Herbarium cited below con- 
stitute our only representation of this concept. Since 
this species is the basis of a distinct genus, it is essential 
to select a new nomenclatorial type, for which I hereby 
designate the excellent collection Schultes & Lopez 9300 
(Tyre in Ames Herbarium No. 68524).
