Figure 6

Bauhinia cheniae sp. nov. from the Oligocene of Ningming, Guangxi, South China. (a- b) Holotype: NHMG 011656a, b. Red arrow indicates the position of the sinus. (c) Line-drawing of holotype, showing the leaf architectural detail. (d) NHMG 011657. Red arrow indicates the position of the sinus. Green arrow shows a folded leaf base. (e) Enlargement of the petiole in d, showing thickened upper and lower pulvini as well as dense, spreading hairs. (f) NHMG 011658. Red arrow indicates the position of the sinus. Green arrows indicate partially overlapped primary veins, implying this leaf is folded. (g) NHMG 011659, with the higher-order veins. Red arrow indicates a short spine in the sinus. Green arrow shows a semicircular laminar joint at the leaf base. Scale bars = 1 cm.
