Original material: [icon] in Mattioli, Pl. Epit.: 853. 1586; [icon] in Morison, Pl. Hist. Univ. 3: 619, s. 15, t. 4, f. 5. 1699; [icon] in Mappus, Hist. Pl. Alsat.: 166, t. 166. 1742; [icon] in Bauhin & Cherler, Hist. Pl. Univ. 3(2): 785. 1651; [icon] in Jussieu in Mém . Acad. Roy Sci. Paris 1740: 263, t. 15. 1740 (see p. 138).

Generitype of Marsilea Linnaeus, nom. cons. (vide Christensen, Index Filicum: LVII. 1906).

Current name: Marsilea quadrifolia L. ( Marsileaceae).

Note: Bobrov (in Novosti Sist. Vyssh. Rast. 21: 20. 1984) indicated 1254.2 (LINN) as type but this collection lacks the relevant Species Plantarum number (i.e. “2”) and was a post-1753 addition to the herbarium, and is not original material for the name. Johnson (in Syst. Bot. Monogr. 11: 39. 1986) treated a Jussieu collection (No. 1599-A, P-JU) as the lectotype but this material would not have been studied by Linnaeus and is not original material for the name either.
