Magnolia pyramidata


Magnolia pyramidata, known so for its pyramid shaped crown, is one of the rarest magnolias in North America and has potential for a landscape tree due to its compact crown and beautiful creamy-white flowers. This rare tree first became known in Europe when brought to England by Bartram in 1806 (Harrar and Harrar 1962, Radford et al. 1968, Godfrey 1988, Dir 1998). It closely resembles Magnolia fraseri, but has an overall smaller stature than this more common species, growing only to 3-7 m (10-20 ft) in height . Leaves are also smaller and are of a peculiar shape: "kitelike".

State Range of  Magnolia pyramidata
Habitat
  Magnolia pyramidata is found on the coastal plain (whereas M. fraseri grows exclusively in the mountains). It grows in mesic woodlands along banks of streams, slopes of steepheads, ravine slopes, bluffs, and uplands (Godfrey 1988).

Distribution
  This is a very local species, rare all across its range. Found in northwestern Florida (especially along the Ochlockonee, Apalachicola, and Escambia rivers), central and southwestern Alabama, southwestern and upper southeastern Georgia (the lower piedmont and coastal plain, scattered), central South Carolina, Mississippi and southern Texas (Harrar and Harrar 1962, Little 1953, Radford et al. 1968, Godfrey 1988, Dir 1998).

Conservation, Ecology & Research

Ecological Relationships
  Ecological relationships are unknown.

Threats
  Excessive coastal development
Road construction, right-of-way maintenance
Hydroelectric facilities, dams
Clearcutting of adjacent hardwoods and conversion to pine
Disturbance by thinning of trees in its immediate proximity
Farm field clearing
Erosion after logging
Human trampling
Invasive species
Bank and ravine slope erosion

Current Research Summary
  Merkle and Watson-Pauley (1994) found that by transferring germinants directly into potting soil, plantlets were more likely to survive and were considered more vigorous.

Current Management Summary
  There is no formal management plan.

Research Management Needs
  Populations need to be identified and monitored. Understanding this species general biology and ecology would be useful in conservation efforts.

Ex Situ Needs
  M. pyramidata is rarely cultivated because propagation is difficult. No cultivars have been selected or hybrids made.
