Epitypification of Tagetes pauciloba
Candolle (1836: 644) indicated that the type specimen of Tagetes pauciloba was collected by Thaddäeus Haenke in Chile. The herbarium and types of Candolle are deposited at G ( Stafleu & Cowan 1976). We found the holotype of T. pauciloba (G 00456857, image avalaible at <http://www.ville-ge.ch/imagezoom/?fif=cjbiip/cjb38/img_183/ GDC026224_1.ptif&cvt=jpeg>) and a specimen indicated as an isotype in P (P 02140934, image avalaible at <http:// mediaphoto.mnhn.fr/media/1444270918729L9yyYg2DY6bJBDGW>) ( Fig. 1 View FIGURE 1 ). Those specimens are poor in vegetative and reproductive material, and they are insufficient for a correct identification of the species, their perennial habit and division of leaves.
Moreover, several authors indicated that the presence of T. pauciloba in Chile is doubtful ( Gay 1849, Reiche 1903, Gutiérrez & Stampacchio 2015). During the study of Chilenian specimens of Tagetes deposited in the greatest herbaria of Argentina and Chile, we have not found any Chilenian specimen that fits the protologue of T. pauciloba . According to Haenke´s biographers ( Presl 1827, Goodman 1972, David et al. 2001), in 1790 he left Buenos Aires on February 24 and arrived to Mendoza on March 17. After 4 days, he continued to Santiago to join the Malaspina Expedition. When he arrived to Santiago, he had collected nearly 1400 herbarium specimens. Though the evidence outlined above is very limited, it is not unreasonable to think that the type material of T. pauciloba was collected by Haenke in Mendoza and not in Chile.
According to the Melbourne Code ( McNeill et al. 2012), we designated an epitype for T. pauciloba ( Fig. 2). This specimen, deposited in BAA (BAA 00004830), was collected by the first author in a field trip to Villavicencio (32º 31,885´S, 69º 01,328´W), Mendoza province, where also the holotype of Tagetes mendocina was presumably found.
