The anatomy of the hypocotyls of Ceriops Arnott (Rhizophoraceae), Recent and fossil 

 -  Botanical Journal of the Linnean Society, 82(2), p.139-164, 1981 .
<br/><br/> Fragments of the hypocotyls of the fossil Ceriops cantiensis Chandler from the Lower Tertiary of southern England and the living Ceriops tagal (Perr.)C.B. Rob. and Ceriops decandra (Griff.)Ding How have been examined by SEM. The living material has also been studied by light microscopy. Great similarity has been revealed between homologous tissues of the Recent and fossil material: the palisade-like epidermis; a two-zoned cortex composed of an outer region of compact collenchymatous tissue and an inner region of aerenchyma; phloem fibres; a large number of small vascular bundles, only some of which have xylem; few xylem elements; similarity of xylem elements; pith region of roundish to shortly oblong cells forming long, bead-like rows in longitudinal view. Evidence is also presented of similarity between Recent and fossil starch grains.
