The name Loosetrife is applied to all species in the Lysimachia genus and, confusingly to members of the Lythrum genus as well.

Lysimachia are sterile to their own pollen and may produce hybrids further confusing the somewhat similar species in this genus.

Similar Species: Several Lysimachia species are similar. The easy distinction of this species is the leaf petioles which are always present and are ciliate their entire length.

Southern Yellow Loosestrife AKA Appalachian Loosestrife (Lysimachia tonsa) is very similar but is found in dry upland areas and the petioles are smooth except perhaps at the base. Lance-leaved Loosestrife AKA Mississippi Valley Loosestrife or officially Lowland Yellow Loosestrife (Lysimachia hybrida) has little if any petiole with the leaf tapering gradually on both ends. It is found in wet areas. Another species know as Lance-leaved Loosestrife is (Lysimachia lanceolata) has petioles only on the lower ovate leaves while most leaves are elongated and tapering with little if any petiole. Whorled Loosestrife (Lysimachia quadrifolia) has tapering leaves with no petiole also but in whorls of three to six, usually four.

Other species are significantly different either having reclining stems that root or the flowers are in terminal racemes or panicles

By: Newcomb, Lawrence and Illustrated by Morrison, Gordon. 1977, Little, Brown and Company, ISBN:0-316-60442-9

One of the best general guides to wildflowers of the North Eastern and North Central United States. Newcomb's key is an excellent, simple method for identifying plants. Newcomb has drawings for almost every plant mentioned that are excellent aids to identifying the species. Though only the more common plants are covered this is often the first book I pick up when trying to identify a wildflower.


Wildflo wers of Tennessee the Ohio Valley and the Southern Appalachians
By: Dennis Horn and Tavia Cathcart and Thomas E. Hemmerly and David Duhl. , ISBN:1551054280

This is perhaps the best of many field guides covering this region. Featuring 446 excellent color photographs (located with the text) and mentioning as similar to those illustrated are another 800 or so species for a total coverage of over 1,200 species. The start of each family section includes line drawings of some of the species showing important features. The text includes the usual description, bloom season, range, habitat and additionally includes information such as medical uses and lore and how the species was named. This is the official field guide of the Tennessee Native Plant Society.
