Abstract
SOTO-TREJO, Fabiola; PALOMINO, Guadalupe and VILLASENOR, José Luis. Chromosome numbers in Asteraceae of the Ecological Reserve of the Pedregal de San Ángel (REPSA), Mexico City, Mexico. Rev. Mex. Biodiv. [online]. 2011, vol.82, n.2, pp.383-393. ISSN 2007-8706.
Mitotic or meiotic chromosome numbers are recorded for 31 species of Asteraceae growing in the Ecological Reserve of the Pedregal de San Angel (REPSA), Mexico City. The chromosome counts of 3 species endemic to Mexico are recorded for the first time: Acourtia cordata (2n= 54), Ageratina cilyndrica (2n= 34), and Viguiera buddleiiformis (n= 17). The results are discussed in relation to the available data for each of the analyzed taxa.
Keywords : chromosome numbers; Asteraceae; Ecological Reserve of the Pedregal de San Ángel; Mexico City; Distrito Federal.
