Rough-leaved loosestrife is a perennial herb endemic to the coastal plain and sandhills of North Carolina and South Carolina. It grows to about 24 inches tall, has whorled leaves in 3s and 4s, and displays 5-petaled yellow flowers from late May to early June (USFWS 1995). Jean Louis Poiret first discovered L. asperulifolia in 1814. Rough-leaved loosestrife occurs mostly in ecotones between longleaf pine uplands and pond pine pocosins. It is associated with six different community types; low pocosin, high pocosin, sandhill seep, wet pine flatwoods, pine savanna, and streamhead pocosin (USFWS 1995). It is a federally endangered species with only 64 populations left, all but one in being in the Coastal Plain of North Carolina. Rough-leaved loosestrife is a misnomer since it has smooth leaves. Its leaves are actually named for their resemblance to Asperula ororata of Europe.

There are sixty-four extant populations, clustered into a few ""metapopulations"" in small areas of the Coastal Plain of North Carolina (with one site in adjacent South Carolina). These probably include a low number of genetic individuals as the plants are clonal and sexual reproduction rates appear to be poor. There are sixteen extirpated populations and the species continues to decline due to landscape trends that are accelerating, especially fire suppression and recreational, industrial, and residential development. Using prescribed burns as a management tool is often difficult or prohibitively dangerous due to the typically high fuel loads within the shrubby pocosins. Where burning does occur, however, the species appears to be able to rebound vigorously - at one site, a sizeable population appeared only months after a fire went through an area that had previously been thick with 2 m tall shrubs.

Frantz (1983, 1984) studied aspects of basic and reproductive biology of Rough-leaved loosestrife. Thorough surveys through North Carolina have been conducted. Research has also been conducted through NCSU investigating changes in flowering stem distribution, pollinator behavior, and seed production following prescribed burns.

Most sites are under some sort of management (generally prescribed fire) by a Federal or State agency or a private conservation organization. These include The Nature Conservancy, the U.S. Forest Service, U.S. Army, U.S. Marine Corps, NC State Parks, the NC Wildlife Resource Commission, and Carolina Power and Light (USFWS 1995)

Research needs include population biology studies such as flower incompatibility, artificial pollination, seed dispersal and establishment, genetic variability, and comparisons between individuals and groups of individuals (TNC 1999). Management needs include more inclusive site protection and habitat management (prescribed fire).

Habitat

Ecotones between longleaf pine uplands and pond pine pocosins typically and occasionally lake and pond margins, hillside seeps, boggy seeps and meadows, and low pocosins (USFWS 1995).

Ecological Relationships

Adapted to fire, this species is often found well within the shrub zone of its preferred habitats (USFWS 1995). Reproduces from cloning and sexual reproduction rates seem to be poor. Many populations may consist of one or very few individuals. An obligate outcrosser, it is pollinated by solitary bees, usually in the genus Dialictus (USFWS 1995).
