Abstract
While editing an account of the Scrophulariaceae for the Flore des Mascareignes, I had to dispose of the plant described by E. J. de Cordemoy in his Flore de l'Ile de la Reunion: 488 (1895), as Bartsia orerensis. A specimen from Cordemoy's own herbarium (MARS), currently on loan to Paris, as well as a small specimen sent to Paris by Cordemoy (? part of the type collection), and another collected by Boivin (also in P) were seen. These prove to belong to the genus Nesogenes (Dicrastylidaceae), a split from the Verbenaceae s.l. The genus comprises 8 species, of which six are from coral islands or coral formations: N. decumbens Balf. f. from Rodrigues, N. dupontii Hemsl. from islands in the Aldabra group, N. glandulosa (Scott Elliott) Mildbr. from Madagascar, N. orerensis (Cordem.) Marais from La Reunion, N. prostrata (Benth.) Hemsl. from Agalega, and N. euphrasioides A. DC. from the Low Archipelago, the Tuamotu Archipelago and the Pomouton Group. The remaining two, N. africana G. Taylor and N. mansfeldiana Mildbr., are both from inland Tanzania, apparently very rarely collected, since neither is represented in Kew Herbarium.
