Hieracium elisaeanum Arvet-Touvet ex Willkomm (1893: 120)

Type (lectotype, designated here):— [ SPAIN. Alicante], Valentia, Sierra de Castalla , July 1890, P. Porta & G. Rigo s.n. ( P barcode P03686242 !) ( Fig. 3 ) .

The protologue of H. elisaeanum includes a complete description in Latin, followed by the provenance and a mention of two gatherings: “In Aragon. australi (Sierra de Javalambre ad rup. calcar. alt. 2000 m, Reverchon, Jul. 1891 et 1892) et regno Valent. (Sierra de Castalla in rupestrib. calc., alt. 1400–1800 m, Porta et Rigo, Jul. 1890)”. The protologue also includes this information: “1879 ter. Hieracium Elisaeanum Arv. Touv. sp. n. in sched. pl. exs. Reverch. Decemb. 1892 et in litt. ad Hervier ( H. baeticum et flocciferum Arv. T. prius in plant. exs. Reverch. anni 1891, H. bellidifolium Porta et Rigo ap. Porta, Vegt. p. 44! non Scheele)”.

We have found a specimen, herbarium sheet with barcode P 03686242, that belong to the Porta & Rigo’s exsiccatum mentioned in the protologue (regno Valent., Sierra de Castalla in rupestrib. calc., alt. 1400–1800 m, Porta et Rigo, Jul. 1890). This sheet bears four complete and well-developed plants, and an original printed label, annotated as: “Nº. / Hieracium bellidifolium Scheele Prodr. II. 261. / Valentina, in rupestribus Sierra Castalla / sol. calcar. 1400–1800 m.s.m. Jul. / Porta et Rigo. iter II Hispanicum 1890” ( Fig. 3 ). This specimen is therefore a syntype of H. elisaeanum , and according to Art. 9.12 of the ICN, it has precedence in the lectotype designation before the uncited specimens and the cited and not quoted illustrations that comprise the remaining original material, if such really exist.

Fortunately, this syntype at P is well preserved and complete, and shows several of the diagnostic characters used to differentiate this taxon as the apex of the rhizome with dense, long hairs, cauline leaves elliptical to ovate–lanceolate; capitula (1–)2–3; involucre 7–9(–11) mm long, with numerous stellate and few glandular hairs; achenes (1.5–) 2.3–2.8 mm long, and matches the traditional concept and current use of the name (see Arvet–Touvet 1913, Zahn 1930, Sell & West 1976, Mateo & Egido 2017, Mateo et al. 2017). Accordingly, we designate as the lectotype of H. the specimen kept at P.
