摘要

Studies on dispersed leaf cuticle from Sindhudurg Formation of Miocene Age from Ratnagiri District, Maharashtra, India have revealed a unique kind of stomatal structure, not reported so far from any living or fossil plant group. The surface of the guard cells shows distinctly marked globular structures arranged in a row. The feature is consistent in all the stomata of the stomatiferous surface, but is not observed anywhere else on the lamina. The possibility of this character being genetically controlled cannot be ruled out. Additionally, the cells of the stomatiferous and non-stomatiferous surfaces of the leaf lamina show both xeromorphic and mesomorphic characters, indicating moderate climatic conditions between humid and dry. However, unicellular fungal spores frequently observed on the cell surface indicate a tropical, humid ecological condition.
