REMARKS

According to the protologue, Pancheria aemula has 3- or 5-foliolate leaves, although the isolectotype at K has 1-, 2- and 3-foliolate leaves. In all the sheets of Schlechter 15642 seen, the leaflets are smaller and narrower than those of Schlechter 15645, the type of P. rivularis , which also has mostly 3- or 5-foliolate leaves, with a few 1-foliolate on some sheets. However, recent collections from the eastern slopes of Mts Ignambi and Panié (e.g., Bradford & Hopkins 1081, 1094, 1096, 1097, Hopkins & Bradford 6636, 6637, 6638, all at K, MO, NOU; Pillon et al. 86, 308, both at K, NOU, P) show there is no discontinuity between P.aemula and P.rivularis , and both these names are now placed in the synonymy of P. beauverdiana (q.v.).

Schlechter 15642 and some of the recent collections are quite variable in the number of leaflets per leaf and occasional leaf irregularities also occur, such as 2- or 4-foliolate leaves. Bifoliolate leaves can have either two equal lateral leaflets and no terminal one, or one normal lateral leaflet and the other fused with the terminal leaflet, making it asymmetric. These types of irregularities are thought to be associated with hybridization in some Cunoniaceae ( Pillon et al. 2009) .
