In the individual examination of each of the 64 AFLP characters in the global data, 16 AFLP markers were found in only L. salicaria. Twenty-seven characters were shared by L. alatum and L. salicaria in a broad sense, with bands both in L. alatum and in either European populations or both the European and the native North American populations. Within the L. salicaria cluster, the introduced North American L. salicaria form a distinct terminal cluster that appears to be derived from within the larger cluster containing the cultivars and the European L. salicaria. Variation in 64 AFLPs was analysed. Lythrum species Lythrum salicaria Name Synonyms Lythrum intermedium Ledeb. Threatened and Endangered Information: This plant is listed by the U.S. federal government or a state. Stems are 4-sided, have slightly raised ridges or wings that run parallel the length of the stems, and are hairless. Ten AFLP characters were identified in L. alatum but not in European L. salicaria. Its flowers are extremely attractive to bees and butterflies. Lythrum Alatum is a native of the US. This is the expected pattern for a locus at which introgression occurred from L. alatum to L. salicaria. It features pink, purple or magenta flowers in dense spikes, up to 18 in. alatum winged lythrum Lythrum alatum var. This plant has no children Legal Status. The morphological intermediacy of these populations is consistent with their being hybrid swarms, but the molecular evidence does not support this conclusion, as the sympatric populations of L. alatum and L. salicaria did not carry any more of the unique L. alatum characters than did the allopatric populations. Of these, eight were found only in L. alatum in North America and as a result had not been transferred to L. salicaria via hybridization. Individual patterns of AFLP variation in the Michigan survey of allopatric and sympatric populations of North American Lythrum salicaria and L. alatum. It can spread through seeds when cross-pollinated with other Lythrum species or through rooting stem fragments. The latter is an aggressive Eurasian plant that invades wetlands and forms dense stands that exclude other species. Lythrum alatum - Winged Loosestrife by bob in swamp. 05 (LSD test). It is in flower from June to August, and the seeds ripen from August to September. Likewise, L. salicaria and L. alatum were well differentiated within the sympatric populations. couldn't find them in any of my reference books. Synonym Full Citation Basionym Type; Lythrum cordifolium Lythrum cordifolium Nieuwland, Amer. Common Name(s): purple lythrum [English] rainbow weed [English] spiked loosestrife [English] purple loosestrife [English] Taxonomic Status: … The field populations of L. salicaria were generally taller and had longer, narrower leaves than those of L. alatum; however, four sympatric L. salicaria populations had mean heights significantly closer to typical L. alatum than typical L. salicaria (HIS, ONP, KIL and SFA), and leaf length in two of the sympatric L. salicaria populations (HIS and SFA) were much closer to the typical mean leaf length of … lanceolatum winged lythrum Legal Status. gracilior Turcz. One character was found in North American L. alatum and in two of the cultivars, supporting a hybrid ancestry for them. Growing alongside Valley Redtsem (Lythraceae) in a muddy patch that had ponding due to wet springs. Note that L. salicaria and L. alatum form well-separated clusters, and the North American L. salicaria are distinct from the cultivars and European L. salicaria. DC. Lythrum salicaria var. Winged Loosestrife can be found growing in the same wet-mesic prairies and meadows, fens, marshes and the borders of water bodies. Leaves are elliptical to lance-shaped, rounded at the base and tapered to a Variation in 279 AFLPs was evaluated. Lythrum alatum var. This indicates that these cultivars have not extensively hybridized with North American L. salicaria, and the integrity of the cultivars in nursery stock remains. The morphological data also supported introgression between L. alatum and L. salicaria, as most of the North American L. salicaria populations had individuals that carried the L. alatum traits alternate leaf placement and 1–2 flowers per leaf axil. This central stem is strongly winged and hairless. Once established, however, L. salicaria can exist in a wide range of soil types. Several scattered patches were found in a former agriculture field that is converting to wet meadow.

Winged Loosestrife, Lythrum alatum is not the same as the botanical scourge, Purple Loosestrife, Lythrum salicaria. Lythrum salicaria Also known as Black Blood, Long Purples, Purple Grass, Rainbow Weed, Red Sally, Rose Loosestrife, Rosy Strip, Sage Willow, Soldiers, Spiked Loosestrife, Willow Weed, Purple Lythrum Vos P, Rogers E, Bleeker M, Reijans M, van de Lee T, Hornes M, Frijters O, Pot J, Peleman J, Kuiper M, Zabeau M. 1Department of Horticulture, 2Department of Fisheries and Wildlife and 3Lyman Briggs School of Science and Department of Zoology, Michigan State University, East Lansing, MI 48824, USA, Oxford University Press is a department of the University of Oxford. One hundred and twenty-three characters were found in L. alatum but not in L. salicaria, which also does not support introgression. In the Michigan screen of sympatric and allopatric populations, there were 123 characters found to be unique to L. alatum and 19 that were shared by some individuals of the two species. The molecular data indicate that introgression may have occurred between the two North American Lythrum species, although the number of genes incorporated into the genome of L. salicaria appears to be limited. Inaccurate comments hurt sellers. Lythrum salicaria is capable of invading a variety of wetland habitats, including marshes, river and stream banks, pond edges, lakes, road site ditches, and reservoirs. Description. Minnesota Environment and Natural Resources Trust Fund, part shade, sun; along shores, wet meadows, wet prairies. This native plant should not be confused with Lythrum salicaria (Purple Loosestrife). Naturalist 3: 265. plant. Purple loosestrife, Lythrum salicaria, is a tall-growing wildflower that grows naturally on banks of streams and around ponds.It has strong, upright stems, topped in summer with long, poker-like heads of bright purple-red flowers. Numbers along branches indicate bootstrap support for that branch (1000 replicates). 2. & A. The characters evaluated here are probably good representatives of the various taxa examined, as they clearly distinguished them in the phylogenetic analysis. The unrooted neighbour-joining dendogram for 40 accessions in a survey of four sympatric and allopatric populations of Lythrum salicaria and L. alatum in Michigan. It is noted for attracting wildlife. All rights reserved. Midl. It was brought to North America in the early 1800s through a number of pathways including Inaccurate comments hurt sellers. Again, only a few L. alatum genes must have been retained in the L. salicaria cultivar background, as only this one marker was consistent with introgression, and no visual morphological differences were observed between the cultivars and wild purple loosestrife populations. Common names are from state and federal lists. Purple loosestrife, Lythrum salicaria, is a tall-growing wildflower that grows naturally on banks of streams and around ponds.It has strong, upright stems, from which long, poker-like heads of bright purple-red flowers appear from midsummer. The seller's sales listing, if you read, is Lythrum Alatum NOT Lythrum Salicaria.. The seller's sales listing, if you read, is Lythrum Alatum NOT Lythrum Salicaria.. Love your site. Plants may be sheared to the ground after flowering or if foliage becomes tattered from insect damage. ), please check the links and invasive species pages for additional resources.
