Reprinted in Prim. Fl. Costaric. 2(1): 63-64 (1898). Annotated as ""paratype"" by Cuatrecasas (1978). Lectotype collection is Tonduz 8944 as designated by W.R. Anderson, Contr. Univ. Mich. Herb. 25: 84 (2007) but US dups bear at least 2 separate dates, therefore some are syntypes rather than isolectotypes.
