Lupinus aridorum


Scrub lupine is a woody perennial herb, and is the only upright, pink-flowering lupine in Florida. On stems that can reach 1 m in height are 4-7 cm long leaves that are pointed at the top and rounded at the base. Both leaves and stems are covered by thousands of tiny silver hairs. In bloom between March and May, the flowers of Lupinus aridorum are a pale-pink color, 4-5 cm long, and appear in groups of 5 to 14 on flowering racemes. The fruit of this species is found in June, and is long (2-2.5cm), woody, and elliptic in shape, tapering to a sharp tip. (USFWS 1999)

Distribution & Occurrence

State Range
  Florida
State Range of  Lupinus aridorum
Habitat
  The species is found in sand pine or rosemary scrub where it grows in both white and yellow sand of the Lakeland or St. Lucie series. Historically, Lupinus aridorum probably grew in scrub gaps until fire suppression and other lack of disturbance resulted in excessive shading and gap closure.

Distribution
  Lupinus aridorum is endemic to Polk, Orange, and Oceola Counties in central Florida where it occurs on the Mt. Dora Ridge in Orange and on the Winter Haven Ridge in Polk County (FNAI 2000). It is unusual among scrub species in that it is not found on the Lake Wales Ridge (USFWS 1999).

Number Left
  Only 15 populations remain with fewer than 1000 plants (FNAI 2000). Most of the populations are on private land. It is found at 10 sites on the Mt. Dora Ridge in Orange and 6 sites on the Winter Haven Ridge in Polk County (FNAI 2000). In 1986, the total population was estimated to be fewer than 350 plants in 11 current populations.

Conservation, Ecology & Research

Ecological Relationships
  No ecological associations known.

Threats
  Principal causes of decline include habitat destruction, trampling by grazers and off-road vehicles, conversion of high pineland and scrub for agricultural purposes (principally citrus groves), and for commercial, residential, and recreational purposes, mowing of roadsides, herbivory, pathogen attacks, and low genetic diversity.

Current Research Summary
  Jack Stout of University of Central Florida monitors this species.
Charba has been studying populations in Orange County by examining dead plants and by culturing parasites found on these plants.

Current Management Summary
  No active management known to be in progress.

Research Management Needs
  Determine current distribution.
Protect and enhance existing populations.
Monitor existing populations of L. aridorum.
Educate the public.
Prevent degradation of existing habitat.
Restore areas to suitable habitat.
Conduct habitat-level research projects.
Monitor habitat/ecological processes.
Germination and propagation techniques and soil seedbank studies.

Ex Situ Needs
  Conduct research on life history characteristics.
Maintain plants in ex situ collections.
