Występowanie gatunków rodzaju "Ludwigia" na Kubie

Abstract

During his stays in Cuba, nine months in 1981-82 and four months in 1989, the author investigated the taxonomic differentiation and geographic distribution of the Ludwigia L. species in this country. Taking a part in some expeditions organized by the Botanical Garden of the University of Havana (Jardin Botanico Nacional), he collected herbarium specimens in various provinces; in the Westem and Middle Cuba (Pinar del Rfo, lsla de la Juventud, La Habana, Matanzas), as well as in the Eastern ones (Guantanamo, Santiago de Cuba, Granma, Camagiiey). He made also the revision of all herbarium specimens preserved in the Cuban Herbaria: older ones (1850-1960) in HAC and more new (1975-1988) in HAJB. The following Ludwigia species have been stated in Cuba: L. peruviana, L decurrens, L erecta, L inclinata, L. sedoides, L octovalvis, L leptocarpa, L hyssopifolia, L. peduncularis (endemie!), L, uruguayensis, L pep/oides, L toru/osa, L microcarpa, L simpsonii, L. stricta (endemie!), L repens, L helminthorrhiza (new for Cuba), and L palustris (?).
