Description
  • Global Rank: N/A
  • Legal Status: N/A
  • Family: Melastomataceae
  • State: AL, DE, GA, NC, NJ, SC
  • Nature Serve ID: 132402
  • Date Inducted in National Collection: 03/08/1989

Rhexia aristosa is an erect, herbaceous perennial that grows to 1 meter tall. It has opposite, linear, lanceolate leaves and large purple flowers that are arranged in a cyme. The Awned meadowbeauty is found in a variety of wet habitats in the Coastal Plain from New Jersey to Alabama. More and more of these wet areas are being drained to make them suitable for activities such as agriculture, pine production, and commercial and residential development. This disruption of natural hydrologic processes has a negative impact on the survival of Rhexia aristosa populations. Compounded with the continuing effects of these activitieserosion, sedimentation, increased nutrient input, and herbicide and pesticide runoffit is clear that this species requires careful monitoring and protection.

Rhexia aristosa is known from relatively few element occurrences throughout a disjunct range; few but some of the very best occurrences are protected. It is vulnerable to habitat alteration and destruction. Very few sites have very large numbers of individuals (>50,000).

Very few occurrences left and very few protected. Recent populations found in Fort Bragg Army Base and Camp Lejeune Marine Base (TNC 1993)

Bernadette Plair (Center for Research of Endangered Wildlife, Cincinnati Zoo and Botanical Garden) has conducted work on the micropropagation of Rhexia aristosa to increase numbers for research and possible reintroduction as part of an IMLS-funded research on a technique for long-term germplasm storage of shoot-tips.

Found in wetlands, wet savannahs, pond beds, flooded bays, cypress bays, pond-cypress savannas, wet pinelands ditches, grass-sedge dominated Carolina bays, vernal ponds, depression meadows, or limesink ponds (dolines).

Ecological Relationships

Research indicates that fluctuations in the water table are required for germination (Thornhurst 1995) Periodic fire is necessary to reduce competition from woody species (NatureServe 2001)
