title: Data from: Generic relationships and classification of tribe Paullinieae (Sapindaceae) with a new concept of supertribe Paulliniodae

description: The current study examines all genera of Sapindaceae tribe Paullinieae
 sensu Acevedo-Rodríguez et al. (2011). Based on molecular phylogenetic
 analyses of trnL intron and ITS sequence data along with critical
 evaluation of morphology, supertribe Paulliniodae is newly recognized and
 morphologically characterized by zygomorphic flowers, thyrses with lateral
 cincinni, corollas of 4 petals, and alternate leaves with a well-developed
 distal leaflet. Paulliniodae contains four successively nested subclades
 designated as tribes Athyaneae, Bridgesieae, Thouinieae, and Paullinieae.
 Athyaneae contains Athyana and Diatenopteryx, and is composed of trees
 with exstipulate pinnately compound leaves, and isopolar, spherical,
 colporate pollen grains. Bridgesieae contains the monospecific shrub genus
 Bridgesia with exstipulate, simple leaves, and isopolar, spherical,
 tricolporate pollen grains. Thouinieae is resurrected and amended to
 include three genera of trees or shrubs with exstipulate trifoliolate or
 unifoliolate leaves. Paullinieae is circumscribed to include only six
 genera (Thinouia, Lophostigma, Cardiospermum, Paullinia, Serjania and
 Urvillea) of climbers or climber-derived shrubs with stipulate leaves and
 a pair of inflorescence tendrils. Guindilia, previously considered a
 member of this clade, is shown to be more distantly related and not part
 of supertribe Paulliniodae. The following 14 new combinations are made to
 incorporate the results of our findings: Serjania biternata, Serjania
 cristobaliae, Serjania dissecta, Serjania guerrerensis, Serjania
 macrolopha, Serjania serjanioides, Serjania sonorensis, Serjania spinosa,
 Serjania tortuosa, Thinouia trifoliata, Urvillea cuchujaquense, Urvillea
 oliveirae, Urvillea procumbens, and Urvillea pterocarpa.

Note branch length heterogeneity in Cardiospermum and the exceptionally long branch for Cardiospermum integerrimum, likely due to GC-content change.Acevedo_etal_Sapind_Supplement Figure 3Fig. S3.
