Resumen

BALDIN, Talita; SIEGLOCH, Anelise Marta; CARDOSO MARCHIORI, José Newton  y  DENARDI, Luciano. Análise comparativa da anatomia da madeira de 41 espécies de Rubiaceae sob enfoque taxonômico. Bol. Soc. Argent. Bot. [online]. 2016, vol.51, n.4, pp.623-634. ISSN 1851-2372.

Rubiaceae is one of the most complex families from a taxonomic point of view, a fact proven by the numerous changes occurring over the years in their internal organization. Based on a literature review, this study investigates the wood of 41 species and utilizes multivariate analysis to verify group formation and placement of species in the subfamilies Ixoroideae, Rubioideae and Cinchonoideae. It can be seen that the group presents structurally homogeneous due to the large number of shared anatomical characters, a fact that has often been stated by others. The species do not completely group according to their subfamilies. The analysis also suggests the change of Calycophyllum genera for Cinchonoideae subfamily while the species Calycophyllum remain united in the dendrogram, demonstrating the homogeneity of the genera.

Palabras clave : Cluster analysis; Wood anatomy; Cinchonoideae; Lxoroideae; Rubioideae; Taxonomy.
