Urban), based in two species: U. pappigera and U. eganioides. It was accepted as such by Reiche (in Fl. Chile 5. 1910), Troncoso (in Darwiniana 18: 295–412. 1974) and Botta (in Bol. Soc. Argent. Bot. 25: 477–483. 1988), this last author synonymised both species, rendering Urbania a monotypic genus confined to the high Andean Puna of Argentina and Chile. In 1940 Moldenke published the name Junellia (in honor of the German botanist S. Junell) and this genus has since been widely recognised in many South American floristic publications, taxonomic revisions and cytogenetic studies such as Covas & Schnack in Revista Argent. Agron. 13: 153–166. 1946; Covas & Schnack in Haumania 1: 32–41. 1947; Cabrera in Dimitri, Encicl. Argent. Agric. Jard. 2(1): 1–85. 1976; Raj in Rev. Paleobot. Palynol. 39: 361. 1983; Beck in Ecol. Bolivia 6: 8. 1985; Poggio & al. in Bol. Soc. Argent. Bot. 25: 542–545. 1988; Botta in Darwiniana 29: 373–377. 1989; Botta in Cabrera, Flora Jujuy 13(9): 63–76. 1993; Botta in Correa, Flora Patagónica 8(6): 147–195. 1999; Botta & Brandham in Kew Bull. 48: 143–150. 1993; Martínez & al. in Darwiniana 34: 1–17. 1996; Atkins in Kubitski, Fam. Gen. Vasc. Pl. 7: 449–468. 2004, and Peralta & al. in Ann. Missouri Bot. Gard. 95: 338–390. 2008.        Nowadays the name Junellia applies to a genus of 39 species and 6 varieties (Peralta & al. in Ann. Missouri Bot. Gard. 95: 338–390. 2008) that grow in South America from Perú and Bolivia to Argentina and Chile. The history of the name was briefly reviewed by Botta & al. (in Taxon 44: 639–640. 1995) in a proposal to conserve Junellia against Monopyrena Speg. and Thryothamnus Phil., which has since been recommended (Brummitt in Taxon 47: 863–872. 1998) and accepted and included first in the St. Louis Code (Greuter & al. in Regnum Veg. 138. 2000).        Junellia differs from Urbania only by the presence of long hygroscopic hairs in the calyx of the latter. Phylogenetic studies using morphological characters (Peralta & al. in Reunión Argentina Cladística, Resumenes: 48. 2004) show monotypic genus Urbania falls within a clade comprising species of Junellia. Recent molecular phylogenetic studies, being carried on by O’Leary & al. (in prep.), based on 4 cloroplast regions (trn L-F, trn S-G, trn S-fm, trn D-T) and the nuclear ITS and ETS, confirm the nested position of Urbania within a monophyletic clade of Junellia. Hence the name Urbania threatens the name Junellia.        Urbania is itself actually a conserved name (McNeill & al. in Regnum Veg. 146: 410. 2006) over the earlier Urbania Valtke (in Oesterr. Bot. Z. 25: 10. 1875. Conservation of Junellia over Urbania would not have an impact over this other conservation, allowing the continued use of Urbania by anyone who wishes to recognise both as distinct genera.             It is here proposed to conserve the name Junellia Moldenke, considering the wide use of this name, avoiding also the necessity of establishing 39 new combinations.
