... these sequences, trees were generated to show the phylogenetic relationships existing between taxa in the family Sapindaceae and closely related taxa of family the Fabaceae. Phylogenetic analysis of the samples with closely related taxa of family Fabaceae revealed that Allophylus conraui, Allophylus griseotomentosus, Cardiospermum corindum, Chytranthus carneus and Deinbollia kilimandscharia were more distantly related to Lessertia species than other members of the family Sapindaceae ( Fig. 1 and 2). Also, phylogenetic analyses revealed that Sapindaceae was monophyletic but paraphyly and polyphyly were shown at subfamilial and tribal levels. The recent suggestion on the taxonomic position of Xanthoceras sorbifolia, Aceraceae and Hippocastanaceae as belonging to the family Sapindaceae is corroborated (Fig 3). The family can be subdivided into four (4) subfamilies: Sapindoideae, Dodonaeoideae, (57% bp) Hippocastanoideae (66% bp) (including Aceraceae) and a monotypic Xanthoceroideae. Xanthoceras is sister to the rest of the family while Hippocastanoideae is sister to subfamily Sapindoideae and Dodonaeoideae. A high degree of paraphyly and polyphyly is also highlighted at subfamilial level, especially in subfamilies Dodonaeoideae and Sapindoideae. This relationship was the same irrespective of the barcode region i.e. either matK or rbcL.
