Type
: not localized. – Note: this is a cultivar with a flat crown. The present authors do not have the Simon-Louis catalogue at hand. Depending on whether or not it contains a description and a definite rank, Schneider’s name would become valid when he provided both. If the publication by Simon- Louis constitutes a valid publication with a definite rank, either Schneider’s or Bean’s combination might become superfluous.
