LeCTOTyPiFiCATiOns AnD nOmenCLATurAL nOTes OF JOsé JerónimO TriAnA’s sPeCies OF DiLLeniACeAe GERARDO A. AYMARD C.1 Abstract. The preparation of treatments of Dilleniaceae for the Flora of Colombia and Flora of ecuador projects required a literature survey, visits to herbaria, and the analysis of types and general collections found on the Internet. The results indicate the need to lecto- typify several species of Dilleniaceae described by the Colombian botanist José Jerónimo Triana. These taxa are based on specimens col- lected during Triana’s participation in the Colombian Chorographic Commission (“Comisión Corográfica”) from 1851 to 1857, under the supervision of Agustín [Giovanni Battista Agostino] Codazzi. Lectotypes for the following six species are proposed herein: Davilla densiflora, Ricaurtea congestiflora, Ricaurtea nitida, Tetracera castaneifolia, Tetracera hydrophila, and Tetracera sessiliflora. Resumen. La preparación de los tratamientos de Dilleniaceae para las Floras de Colombia y ecuador han requerido de una revisión de literatura, visitas a numerosos herbarios, y el análisis de material tipo y colecciones en el Internet. Como resultado se ha observado la necesidad de realizar lectotipificaciones de varias especies descritas por el botánico colombiano José Jerónimo Triana en el siglo XiX. estas especies están basadas en ejemplares colectados por Triana durante su participación en la Comisión Corográfica, dirigida por Agustín [Giovanni Battista Agostino] Codazzi, desde 1851 hasta 1857. en la presente contribución se proponen lectotipos para las siguientes seis especies: Davilla densiflora, Ricaurtea congestiflora, Ricaurtea nitida, Tetracera castaneifolia, Tetracera hydrophila, and Tetracera sessiliflora. Keywords: Dilleniaceae, Lectotypification, José Jerónimo Triana, Colombia The designation of lectotypes is necessary because The plants described by José Jéronimo Triana (1828– holotypes were not usually selected for most of the species 1890) in 1858 and then by Triana and Jules Émile Planchon described in the 18th and 19th centuries, particularly when (1833–1990) in 1862 typically need the designation of authors cited several collections or syntypes (McNeil, 2014). lectotypes (Kirkbride Jr., 1982). Triana was a notable Many descriptions often referred to a “type” in a Colombian medical doctor and botanist who was an active superficially and ambiguous way, which again often requires participant in the Colombian Chorographic Commission the designation of a lectotype. The nomenclatural rules define (“Comisión Corográfica”) from January 1850, to December a lectotype as “a specimen or other element selected from the 1856, under the supervision of Agustín [Giovanni Battista original material” (McNeil et al., 2012). In the past, many Agostino] Codazzi (Dugand, 1944; Díaz-Piedrahita, 1988, authors operated under the now discarded assumption that 1996; Acuña, 2011). He collected nearly 8,000 specimens the first specimen cited was automatically the type, a purely during his travels (Parra-Osorio, 2017). Working on a bibliographical exercise with no element of selection or Prodromus florae Novo-granatensis (Díaz-Piedrahita & choice (Prado et al., 2015). Moreover, references to a “type” Lourteig, 1989), Triana was the first Latin-American botanist were often to “a collection” with several replicates, in the to study Dilleniaceae (Triana, 1858; 1862; Aymard, 1997, same or in different herbaria, some examined by the author 2007). Typically, however, he only provided a general type or not, or to a collection locality, where the same collector location in his protologues, or quoted several collections or several collectors may have gathered specimens. In most from places closely located, and many species need some flowering plant groups, collection with several replicates basic nomenclature work as far as type designation is in different herbaria could have been made from a single concerned. individual, but in other groups with small individuals it is This contribution precedes the preparation of treatments not always true that representatives of a particular collection of Dilleniaceae for the Flora of Colombia and the Flora of represent the same species. Currently, the idea is to choose Ecuador projects, the goal of which is to clarify the status, a specimen that the author had at hand (“original material”) nomenclature, and typification of six names from the genera and alternatively might have had designated as holotype. Davilla Vand., Doliocarpus Dol., and Tetracera L.

The selection of lectotypes was based on 2015), which offered access to botanical literature published the protologues and the examination
