Calviño, Carolina Isabel & Martínez, Susana Graciela, 2018, Typification of plant names belonging to subfamily Apioideae (Apiaceae) for the Flora of Argentina, Phytotaxa 379 (2), pp. 153-161 : 158

24. Peucedanum oreopansil Grisebach ≡ Austropeucedanum oreopansil ( Grisebach 1879: 147) Mathias & Constance

(1952: 366).

Lectotype (designated here):— ARGENTINA. Tucumán, Sierra d. Cuesta del Garabatal, auf d. feuchten Baden d. Alisohange mit Escallonien , Ende Jan 1874, Lorentz & Hieronimus 1055 ( GOET011291 !; isolectotype, GOET011292 !).

Notes:—Grisebach in his Symbolae ad Floran Argentinam (1879) based his descriptions on material collected by Lorentz and Hyeronymus ( Hunziker 1960). In the original publication of Peucedanum oreopansil, Grisebach (1879) did not indicate a type specimen, but he provided information on the type locality: “T: Cuesta del Garabatal, in regione Aliso cum Escalloniis in locis humidis”. When Mathias & Constance (1952) transferred Peucedanum oreopansil to Austropeucedanum , they indicated Lorentz & Hieronimus 884 as the type. However, this number corresponds to the numeration of the species in Grisebach´s work (1879), and not to the collection number (in fact, Lorentz & Hieronimus 884 is not even an Apiaceae ). The specimen GOET011291 was selected as lectotype because the plant material agrees with the description, and the labels match perfectly with the protologue in locality specifications. Our study of type material also included the examination of the following specimens from Tucumán with the same collectors and dates earlier than 1879: CORD00006021, CORD00006022, GOET007370, K000537234, S05-4106 and US 01107833.
