| contents | Colima (Tigridieae: Iridaceae), a new genus from western Mexico and a new species: Colima tuitensis from Jalisco Luis Ortiz Catedral Aarón Rodríguez Biología Colima Mexico Iridaceae new genus Nemastylis Based on cytological, palynological, and DNA evidence, we propose the elevation of Nemastylis subgenus Colima to the generic status to include Nemastylis convoluta. Thenew genus is characterized by its united filaments, free anthers with longitudinal dehiscence, style divided into three branches with six arms at right angles, apical stigmatic surface, absence of nectaries, lack of mucro between the style arms and bisulcate pollen grains. A preliminary study based on morphological variation and DNA sequences variation suggests a close phyllogenetic relationship between Colima and the genera included within the subtribe Tigridiinae. However the relationships of Colima at the generic level are not fully resolved by the molecular analysis. Finally, we describe and illustrate a new species of Colima from El Tuito, Jalisco. This new species is characterized by its winged stems,pedicels, ovaries and fruits. In addition, the tepals are creamy yellow, oblanceolate with acuminate apex and a smaller androgynoecial apparatus than that of Colima convoluta. 2003 artículo científico 0187-7151 https://www.redalyc.org/articulo.oa?id=57406505 en http://www.redalyc.org/revista.oa?id=574 Acta Botanica Mexicana application/pdf Instituto de Ecología, A.C.
