<- Bromeliaceae Literature (most recent first) and Bio — Ivón Ramírez M.

photoVenezuelan-born botanist (1959), naturalized Mexican in 2003. She undertook her bachelor's degree in biology at the Central University of Venezuela, Caracas, with a thesis on the genus Encyclia (Orchidaceae) in Venezuela and graduated in 1987. During the latter part of her undergraduate studies Ramírez Morillo worked as an assistant in the National Herbarium of Venezuela (1985-1988) and following this she moved to the U.S.A., to the Missouri Botanical Garden. Serving as an assistant in herbarium MO, she worked towards her master's degree through a revision of the Neoregelia subgenus Hylaeaicum, a qualification she received from the University of Missouri-St. Louis in 1991. Immediately following this, she embarked upon her doctorate studies at the same university where she worked as an assistant teacher and, researching the genus Cryptanthus (Bromeliaceae), was awarded her PhD in 1996 with a thesis entitled “Systematics, phylogeny, and chromosomal evolution of Cryptanthus (Bromeliaceae)”.

Since 1997 Ramírez Morillo has worked for the Centro de Investigación Científica Yucatán, A. C. (CICY) as a professor and researcher. Her work has centered on Mexican bromeliads, especially their taxonomy, floristics and reproductive biology, including genera such as Tillandsia and Hechtia. She has delivered talks nationally and internationally, conducted thesis of several alumni at the undergraduate and graduate levels. She has also published more than 125 papers, more than 10 book chapters and two books including “Guía Ilustrada de las Bromeliaceae de la porción mexicana de la Península de Yucatán” (published 2004). Married to fellow Venezuelan botanist Germán Carnevali Fernández-Concha together they have three children and a grandson. The species Anthurium iramirezae G.S. Bunting and Anthurim ivoniae Carnevali & Croat (Araceae), Tassadia ivonae Morillo (Apocynaceae), Tillandsia ramireziana J.J. Ancona & Pinzón (Bromeliaceae) and Encyclia ivonae Carnevali and G.A. Romero-González (Orchidaceae), have all been named in her honor. Additionally, she has participated in the publication of more than 126 binomials, 98 of them are new species to Science, mainly orchids and bromeliads.
