Taxonomic and nomenclatural notes on neotropical Commelina (Commelinaceae), and an identification key for Brazil, Guyana, Paraguay, Suriname and Uruguay Author Hassemer, Gustavo text Phytotaxa 2017 2017-04-11 303 2 101 117 http://dx.doi.org/10.11646/phytotaxa.303.2.1 journal article 10.11646/phytotaxa.303.2.1 1179-3163 13687569 5. Commelina pohliana Seubert (1855: 265 , tab. 36[II]) Lectotype (designated here): —[illustration] tab. 36(II) in Seubert (1855) . = Commelina erecta Linnaeus (1753: 41) Lectotype (designated by Clarke 1881: 181 ):—[illustration] tab. 77 in Dillen (1732) . Notes: —The protologue of C. pohliana provides the following information about the type: “ Crescit prope Ponzo Allegre prov. Minarum Geraës: Pohl in Herb. Caes. Vindob. n. 891 ”. No extant specimens that could be considered original material for this name could be located at W (Armin Löckher, pers. comm.), nor at any other herbaria consulted. Therefore, the only extant material for typification is the illustration (tab. 36[II]) provided in Seubert (1855) , which I designate here as lectotype of the name C. pohliana . Commelina pohliana has been accepted as a synonym of C. erecta in Clarke (1881) , Barreto (1997) and Zuloaga et al. (2008) , to which I agree.
