Typification of fourteen Linnaean names in the genus Hieracium (Compositae)

Abstract

The typification of fourteen Linnaean names in Hieracium, viz. H. aurantiacum, H. auricula, H. chondrilloides, H. cymosum, H. dubium, H. glutinosum, H. hedypnoides, H. incanum, H. murorum var. pilosissimum, H. murorum var. sylvaticum, H. porrifolium, H. pumilum, H. sabaudum and H. tomentosum, is discussed. The designation of the nomenclatural types is based on the consultation of Linnaeus's original material and the literature cited in the respective protologue. The names are lectotypified using specimens preserved at UPS‐BURSER and LINN, and two illustrations of Boccone and Dillenius. Linnaeus's original material of H. pumilum and H. pyrenaicum var. helveticum could not be found. A specimen in S‐LINN that best conforms with the diagnosis for H. pumilum is selected as the neotype for that name. The application of the name H. pyrenaicum var. helveticum appears uncertain, and therefore it is treated as nomen ambiguum. Finally, epitypes are designated for H. porrifolium and H. tomentosum due to ambiguity in the interpretation of the lectotypes.

The Taxonomic Circumscription and Nomenclatural History of Pilosella suecica (Asteraceae): A Special Case of Grey Literature in Taxonomic Botany

“…This text is not a nomenclatural reference (because Fries abandoned H. dubium as an ambiguous and therefore unusable name and did not include it as a nomenclatural synonym) but a reference to his earlier [40] misapplication for the same plant. Similarly, this synonym was cited pro parte (regarding Swedish plants only, i.e., excluding foreign synonyms, one of which subsequently provided a lectotype of this species name [17]) in the first Hieracium monograph [35]. For this reason, H. suecicum is not a superfluous and illegitimate name as erroneously believed by Bräutigam and Greuter [28].…”

“…Type collections of the oldest species names in Pilosella have only recently been examined (e.g., [17]). In some cases, like P. fallax (Willd.)…”

Typification of the Linnaean name Crepis vesicaria (Compositae: Cichorieae) revisited

“…As part of the studies on the nomenclature of the Cichorieae species described by Linnaeus (see Ferrer‐Gallego & Mateo, 2015; Ferrer‐Gallego & al., 2015; Ferrer‐Gallego & Talavera, 2016; Ferrer‐Gallego, 2021b), the original material and typification of the name Crepis vesicaria have been studied. The aim of this paper is to lectotypify this name according to the International Code of Nomenclature for algae, fungi, and plants ( ICN , Turland & al., 2018).…”
