Critical comments on the types of two 19th-century North American plant names

We identify specimens belonging to the original material of the names Onosmodium molle Michaux (Boraginaceae) and Verbena riparia Raf. ex Small & Heller (Verbenaceae). We designate the lectotype for O. molle. On the other hand, we present evidence that original material of V. riparia is indeed the holotype, which supersedes a previous lectotype designation.


Lithospermum molle New Jersey Onosmodium molle Rafinesque Tennessee United States of America Verbena officinalis Verbena riparia 



We would like to thank Fred Barrie, Michael Nee, Nataly O'Leary and Thomas Zanoni for their constructive comments on earlier versions of the manuscript that greatly improved its quality; to the curators and staff of the herbarium P of the Muséum National d'Histoire Naturelle of Paris for providing the high-resolution image of the lectotype of Onosmodium molle; also to the curators and staff of NY herbarium, especially Amy Weiss, for digitizing the Verbena riparia holotype.
