Sur la présence de l'Enhalus acoroide (L.f.) Roem. et Schultes au littoral du Viêtnam

In the "Flore Générale de l'Indochine" three species of phanerogams have been described: Halophila ovalis (R. Br.) Hook. f., Diplanthera uninervis (Forsk.) Aschers. and Ruppia rostella Koch in Rchb. In 1954, Dawson added to this list Halophila Beccari Aschers. and Thalassia hemprichii (Ehrenb.) Aschers. Even Mr. Feldmann found in the herbarium of the Oceanographic Institute of Nha-Trang, the Cymodocea rotundata (Ehrenb. & Hernpr.) Asch. & Schweinf., that the authors found in Cua-Be (Nha trang), Qui-Nhon and Da-Nang (Tourane).
