Fig. 6From: Bilobate leaves of Bauhinia (Leguminosae, Caesalpinioideae, Cercideae) from the middle Miocene of Fujian Province, southeastern China and their biogeographic implicationsLeaf morphology of Bauhinia fotana from the middle Miocene of Fujian Province, southeastern China. a-b Epitype, PB21579 and its line-drawing, showing the detailed leaf architecture. Note that this leaf was torn along the midvein and then became partially overlapped of two lobes after a twist during the process of fossilization. c PB21580, showing basal actinodromous primary veins (1°). Note that the apical parts of the leaf were deformed. d Holotype, PB21577, indicating a relatively complete leaf with stout, basal actinodromous 1°. e-f PB21581a, b, showing the part and counterpart specimens of a leaf. Note that this leaf was torn near the midvein, and the right lobe was partially folded. Red arrows in (d, f) refer to a partially preserved petiole. Scale bars = 1 cmBack to article page
