The objective of the present study was to make the morphological characterization of 47 accessions of roselle (Hibiscus sabdariffa L.) from the state of Guerrero, Mexico. The morphological evaluation included 50 characters which were separated in 40 quantitative and 10 qualitative. From these variables, 25 quantitative and five qualitative characters with high variability (P ≤ 0.04) were selected. Data were analyzed by means of correlations, regressions, discriminating analysis of groups and correspondence. With six quantitative and five qualitative characteristics it was possible to make the distinction and morphological grouping of the genotypes in four groups. The quantitative characters that contributed the most to the differentiation of the genotypes were length at the base of the main lobe of the leaf, fruit length, fruit perimeter, vertical length of the leaf, angle of the left lobe of the leaf, chroma (C) of the flower and color of the leaf quantified with a colorimeter (L). The qualitative characters that had the most influence were those associated with leaf color, earliness, stem color, color of bracts and the presence or absence of melliferous glands.
