Starch grains are a ubiquitous component of plants that have been used in tandem with phytoliths, pollen, and macrofossils to reconstruct past floral diversity. This tool has yet to be fully explored for aquatic plants, specifically seagrasses, which lack phytoliths and are rarely preserved as macrofossils or pollen. If starch grains in seagrasses are morphologically distinct, this method has the...
Species of the aquatic genus Nymphoides have distinct and highly modified inflorescence architectures in which floating leaves support aerial flowers. Three inflorescence types exist in Nymphoides, and these differ by their relative elongation of internodes and the number of flowers per node. We compared organ composition and arrangement among the three inflorescence architecture types in representative...
