Comment:
published simultaneously with P. leptostachyus f. purpureus Freytag and based on the same type, thus Melbourne ICN Art. 36.2 (see Ex. 14) applies and neither of these names is validly published. The exception to this rule, where the same combination is simultaneously used at different ranks, does not apply in this case because the two final epithets are not the same
