ABSTRACT Reports of the angiosperm macrofossils from the Early Cretaceous sediments of India are relatively poor, with only one report from the Krishna-Godavari Basin. The present study documents a monocotyledon leaf fossil from the Barremian-Aptian (Early Cretaceous) of Gangapur Formation, Pranhita-Godavari Basin, India. The present fossil leaf placed under a new genus Sahniophyllum and it is characterised by the ribbon shaped leaves, with parallel venation, arranged in rosette form suggests its probable affinity with Hydrocharitaceae. The taphocoenosis demonstrates its autochthonous preservation and aquatic habitat.

Foi analisada, no presente trabalho, a morfologia polínica de nove espécies arbóreas pertencentes a seis gêneros (Acnistus, Aureliana, Brunfelsia, Capsicum, Cestrum e Solanum) da família Solanaceae ocorrentes no Estado de Santa Catarina, Brasil. Os grãos de pólen foram agrupados em seis tipos polínicos correspondendo aos seis gêneros examinados. Foi elaborada uma chave de identificação para as nove espécies. Espécies de um mesmo gênero diferem somente por características morfológicas secundárias, mantendo um único tipo polínico.

The pollen morphology of nine tree species belonging to six genera (Acnistus, Aureliana, Brunfelsia, Capsicum, Cestrum, and Solanum)of the Solanaceae family and occurring in the state of Santa Catarina, Brazil, was considered in the present paper. The pollen grains were grouped into six pollen types corresponding to the six genera examined. An identification key for the nine species was presented. Species of a same genus differ by morphological secondary features only, maintaining an unique pollen type.
