Taxonomical identification: Epidermis of Nymphaea nouchali
First publication: Gelorini, V., Verbeken, A., van Geel, B., Cocqyt, C. and Vershuren, D. (2011) Modern non-pollen palynomorphs from East African lake sediments. Review of Palaeobotany and Palynology 164, 143–173

Description: Globose to shaped like a rounded square in outline, subhyaline to pale yellow, 38–58 μm in diameter, consisting of 7–8 cells, each 17–25 × 14–22 μm. Cell walls covered by a very fine, wavy net-like sculpture, central cell globose, marginal cells tetragonal. Only occasionally found in assembled condition. This morphotype belongs to the epidermis of Nymphaea nouchali, which is the only living Nymphaea species found in the 20 lakes studied (Lebrun, unpublished CLANIMAE data), and can easily be mistaken for coenobia of the coccal green alga Pediastrum privum (Printz) E.Hegewald (see Komárek and Jankóvska, 2001).
