“…The circumscription of the family as well as the relationships among subfamilial entities have been widely challenged since the very first worldwide treatment of Sapindaceae sensu stricto (s.s.) (including subfamilies Sapindoideae and Dodonaeoideae) proposed by Radlkofer (1890Radlkofer ( , 1933; for a review see Harrington et al, 2005). For instance, several genera within the Sapindoideae (e.g., Tinopsis and Plagioscyphus from Madagascar; Capuron, 1969) were shown to be morphologically transitional between tribes described by Radlkofer (1933), which prevented the recognition of unequivocal tribes.…”

a b s t r a c tThe economically important soapberry family (Sapindaceae) comprises about 1900 species mainly found in the tropical regions of the world, with only a few genera being restricted to temperate areas. The infrafamilial classification of the Sapindaceae and its relationships to the closely related Aceraceae and Hippocastanaceae -which have now been included in an expanded definition of Sapindaceae (i.e., subfamily Hippocastanoideae) -have been debated for decades. Here we present a phylogenetic analysis of Sapindaceae based on eight DNA sequence regions from the plastid and nuclear genomes and including 85 of the 141 genera defined within the family. Our study comprises 997 new sequences of Sapindaceae from 152 specimens. Despite presenting 18.6% of missing data our complete data set produced a topology fully congruent with the one obtained from a subset without missing data, but including fewer markers. The use of additional information therefore led to a consistent result in the relative position of clades and allowed the definition of a new phylogenetic hypothesis. Our results confirm a high level of paraphyly and polyphyly at the subfamilial and tribal levels and even contest the monophyletic status of several genera. Our study confirms that the Chinese monotypic genus Xanthoceras is sister to the rest of the family, in which subfamily Hippocastanoideae is sister to a clade comprising subfamilies Dodonaeoideae and Sapindoideae. On the basis of the strong support demonstrated in Sapindoideae, Dodonaeoideae and Hippocastanoideae as well as in 14 subclades, we propose and discuss informal groupings as basis for a new classification of Sapindaceae.

“…The genera of both studied species are considered phylogenetically related by many authors (ACEVEDO-RODRIGUEZ, 1993;FERRUCCI, 2000;HARRINGTON et al, 2005;WECKERLE;RUTISHAUSER, 2005). The presence of dorsal wings, lighter spongy tissue, inflated locules and the easy opening by the spongy tissue in the septa of U. ulmacea could represent a transition state between the samaroid schizocarp formed by Serjania and the septifragal capsule produced by Cardiospermum.…”

ABSTRACT. The pericarp development of Serjania communis Camb. and Urvillea ulmacea Kunth was described to expand the structural knowledge of Sapindaceae fruit. Ovaries and fruits were analyzed with usual techniques in plant anatomy. Ovary is structurally similar and the occurrence of glandular and non-glandular trichomes varies between species. In S. communis, the samaroid schizocarp has proximal wings and distal cavities; in U. ulmacea, the fruit presents septicidal and septifragal passive dehiscence and each seed chamber presents a dorsal wing. The unistratified exocarp has long pluricellular, uniseriate and sparse trichomes in U. ulmacea. The mesocarp is spongy, parenchymatous and in S. communis it presents three distinguished regions. Dorsal, lateral and ventral vascular bundles are more developed in S. communis and fiber caps on the phloem in the lateral bundles have an important role on the mericarp separation. The endocarp derives from the adaxial meristem and its oblique and tangentially elongated cells become lignified. The wings originate from a more active meristem -at the ovarian edges -and by intense divisions of ovarian mesophyll in this region. Fruit of U. ulmacea can represent a transition state between the samaroid schizocarp formed by Serjania and the septifragal capsule produced by Cardiospermum.Keywords: development, fruit, Sapindaceae, samara, capsule.Ontogênese do pericarpo de Serjania communis Camb. e Urvillea ulmacea Kunth (Sapindaceae) com ênfase no aparelho de dispersão RESUMO. O presente estudo descreve aspectos morfológicos e o desenvolvimento do pericarpo de Serjania communis Camb. e Urvillea ulmacea Kunth ampliando o conhecimento estrutural dos frutos de Sapindaceae. Foram coletados e analisados ovários e frutos seguindo técnicas usuais em anatomia vegetal. O ovário estruturalmente similar e a ocorrência de tricomas glandulares e não glandulares varia entre as espécies. Em S. communis, o esquizocarpo samaroide apresenta ala proximal e cavidade distal; em U. ulmacea, o fruto apresenta deiscência passiva septicida e septifraga e cada cavidade seminal apresenta uma ala dorsal. O exocarpo uniestratificado tem tricomas pluricelulares longos, unisseriados e esparsos em U. ulmacea. O mesocarpo é parenquimático e esponjoso e em S. communis apresenta três regiões distintas. Os feixes vasculares dorsais, laterais e ventrais são mais desenvolvidos em S. communis e as calotas de fibras sobre o floema nos feixes laterais participam da separação dos mericarpos. O endocarpo deriva do meristema adaxial e suas células oblíqua e tangencialmente alongadas tornam-se lignificadas. As alas originam-se de um meristema mais ativo -nas arestas do ovário -e por divisões intensas no mesofilo ovariano nessa região. O fruto de U. ulmacea pode representar a transição entre o esquizocarpo samaroide de Serjania e a cápsula septifraga de Cardiospermum.

“…A recent molecular study of the Sapindaceae (Buerki et al 2009), with two samples of H. foliosum (Hiern) Bullock from the African continent and one of H. perrieri, demonstrated the polyphyly of the genus with H. perrieri belonging to a genus other than the continental african Haplocoelum. The polyphyly shown in an earlier molecular study (Harrington et al 2005) is most likely due to a misidentification of Edwards KE501, because the name H. gallaense (Engl.) Radlk.…”

Summary. The new species Haplocoelum gabonicum Breteler (Sapindaceae) from Gabon and adjacent Congo is described and illustrated. Morphologically it is most similar to H. acuminatum Radlk. ex Engl. and H. congolanum Hauman. It differs from these species by foliar characters such as the non-alate rachis, the presence of a rudimentary lower pair of leaflets, and the entire acumen of its leaflets. These differences are summarised in a key. H. congolanum is synonymised under H. acuminatum. The latter species is lectotypified and its authorship corrected.
