Comment:Hershkovitz refers to an unpublished manuscript by Carolin and ascribes authorship of all new combinations in Rumicastrum from that manuscript to Carolin alone. The existence of Carolin's unpublished work is not regarded as constituting a contribution by Carolin to the present publication under ICN Art. 46.5 (Shenzhen Code, 2018), so authorship is here given as Carolin ex Hershk.
