Galactia smallii


Galactia smallii is a delicate, trifoliate sprawling herb with pink or lavender pea-like flowers (Avery and Loope 1980, Herndon 1981, Isley 1990). It is endemic to Miami-Dade County's rare pine rockland ecosystem (Hainds et al. 1999, Coil 2000, Fisher 2000). Currently, G. smallii is known from only 6 sites, but a few more populations likely exist on private land (USFWS 1999).

Distribution & Occurrence

State Range
  Florida
State Range of  Galactia smallii
Habitat
  Pine rocklands, in areas with higher elevation and lower shrub cover than preferred by other Galactia spp (O'Brien 1997, 1998).

Distribution
  G. smallii is known from Miami-Dade County, Florida (O'Brien 1997).

Number Left
  There are six known populations of G. smallii left in Miami-Dade County. Most of these have less than 50 plants (Fisher 2000). There is no information on the number or status of privately owned populations.

Conservation, Ecology & Research

Ecological Relationships
  • Known pollinators are three species of bees, one species of wasp, and the Cassius blue butterfly (Leptotes cassius theonus) (USFWS 1999)
• This species flowers more profusely after a burn (USFWS 1999)

Threats
  • Habitat loss and fragmentation
• Encroachment of the exotic species Brazilian pepper (Schinus terebinthifolius) and cane grass (Neyraudia reynaudiana) (O'Brien and Koptur 1995).
• Fire suppression

Current Research Summary
  J. O'Brien (1997, 1998) studied habitat preferences as part of a M.S. thesis at Florida International University.

Current Management Summary
  G. smallii is found on private lands as well as land owned and managed by Miami-Dade County.

Research Management Needs
  Management and research needs include population identification and protection on private lands and potential locations for reintroduction. Research and implementation of fire management is also needed.

Ex Situ Needs
  Fairchild Tropical Garden has a small ex situ collection of G. smallii. More seed collection and/or propagation would be needed if an outplanting were to take place.
