Jul 20, 2020 - Ludwigia peploides (creeping water-primrose) is a perennial aquatic plant (family Onagraceae) that forms very dense, virtually impenetrable mats which restrict fishing and boat access. The allelopathic potential of two invasive alien Ludwigia [Onagraceae: L. peploides (Kunth) Raven and L. grandiflora (Michaux) Greuter and Burdet], that have developed quasi-monotypic stands in many aquatic ecosystems in France, was investigated. Raven and Ludwigia grandiflora (Michaux) Greuter and Burdet ssp. Ludwigia peploides - Floating primrose willow. glabrescens (Kuntze) P.H. 90(2): 143-148. Ludwigia peploides is also found on sediment bars on river banks and in wet meadows (Laugareil, 2002; Zotos et al., 2006), and colonizing brackish waters (Mesleard & Perennou, 1996). More recently, hexapetala was defined as a subspecies of grandiflora (Nesom and Kartesz 2000). The grass carp (white amur, Ctenopharyngodon idella) is a relatively nonselective herbivorous fish that will consume some Ludwigia species, particularly those producing prostrate, floating mats. Its growth is favoured by water eutrophication but the plant is able to develop in oligotrophic environments. Since allelopathy involves the release of compounds into the environment, the water of monospecific experimental cultures was directly tested … Foliage Leaves are alternately arranged and vary in shape and size, from lanceolate to ovate. Water primroses are scattered throughout the US (Kartesz, 1999). Image 5392312 is of creeping waterprimrose (Ludwigia peploides ) flower(s).
