Elena Siqueiros-Delgado Biología culm anatomy Bouteloua Gramineae Transverse sections of mature flowering culms of Boutelouinae were analyzed toexplore the usefulness of the culm anatomy to assess phylogenetic relationships. Fifty-fivetaxa were surveyed from the field and greenhouse collections. Although leaf anatomy inBoutelouinae has been shown to possess systematic utility, culm anatomy has been verylittle explored. In the Boutelouinae, only few traits of the culm middle internodal regionwith phylogenetic value, were found. Kranz structures (cells and radial chlorenchyma),number and position of the vascular bundles, and sclerenchyma girders are some culmanatomy characters that can be useful for inferring relationships at higher levels (family,tribes, genera). Culm anatomy suggests close relationships between B. eriopoda and B.eriostachya, and between B. ramosa and B. breviseta, and supports the inclusion of thesatellite genera into Bouteloua. The Kranz structures and chloroplast shape appear to be themost variable features of this region of the culm 2007 artículo científico 0187-7151 https://www.redalyc.org/articulo.oa?id=57407802 en http://www.redalyc.org/revista.oa?id=574 Acta Botanica Mexicana application/pdf Instituto de Ecología, A.C.
