Sloanea ungeri (HEER) MANCHESTER et Z. KVAČEK

Sloanea ungeri (HEER) MANCHESTER et Z. KVAČEK is based on spiny capsular fruits with long peduncle and hypogynous disk that conform well with the morphology of extant Sloanea ( Manchester and Kvaček 2009). It is disconcerting, however, that no obvious leaves of Sloanea have been found in co-occurrence. Leaves of extant Sloanea have prominent thickening and a twist at the junction of lamina with petiole that has not been observed among the leaves associated with these fossil fruits. One of the specimens was referred to as “elliptic fruit with a fringe of hairs or filaments” ( Brown 1962, pl. 67, fig. 35).
