Eucastalia, and in air-canals and venation to Lotos, Nelumbo or Victoria ; but the trimerous symmetry has not come down to us in any living form. Anoectomeria brongniartii (Casp.) Sap. (1865 a, 6) (= Nymphaea Are- thusae Brongn., 1822, not of Weber, 1850 ;—Nymphaeites Brongniartii and Arethusae Casp., 1856) flourished in Eocene times, being plentiful in the littoral chalk marls of the Marseilles basin. A. media Sap. (1894 c] occurs in the Aquitanian (Miocene), and A. nana Sap. in the tertiary of Alsace (Mieg, etc., 1890), although Schenk(i888) speaks of the genus as restricted to the Oligocene. Nymphaea polyrhiza Sap. (1865 a) (= N. eocenica Sap., 1861, in part) from the Aqui- tanian of St. Jean de Garguier, resembles Anoectomeria in the trimerous flower, and should on that account be removed from the genus Nymphaea ; it also has a large number of air-canals in the petiole. In other ways, however, it is near to N. gyp- soru»i Sap. (1865 n}. On some other species statements are conflicting. JV. calophylla was at first (Saporta, 1861) said to have denticulate leaves, but in 1894 (t>) the same writer describes the leaves as entire. The venation of this, as of most other tertiary Nymphaeas, was similar to that of Anoectomeria, and very suggestive of the Lotos group ; but they had the rhizome and stipules of Eucastalia. Saporta considers that their type has become entirely extinct. In this list are included also -Ar. gypsorum Sap., N. ame- liana Sap., N. nalini Sap., N. rousscti Sap., and N. dumasii Sap. (Fig. 76). Nymphaea mimita Sap. is near of kin to N. tctragona, and N. cor data Sap. to the smaller forms of N. alba, while N. latior Sap. resembles the large N. alba of Greece. Wessel and Weber (1855) compare their ^V. lignitica (— Nytnphaeites lignitica Casp.) from the lignites of Rott in the lower Rhine region with N. alba, with regard to the shape of the leaf.
