The form was published as puberula. However, in the title of this publication, Miquel refers to his Systema Piperacearum (as 'Syst. Pip. Ined.'), effectively issued but 8 months later, in which the form appeared as pubescens. Moreover, when Miquel raised the form to variety (1858) it is also called pubescens. For these reasons 'pubescens' is considered as the epithet orignially intended to be published [Mathieu, pers. comm, 2014].
