NatureServe Global Conservation Status Factors

Range Extent Comments: Bahamas, West Indies and a variant(?) in Florida (Correll and Correll 1982); also in Cuba, Dominican Republic, and possibly Lower Antilles (Ledin 1951); not listed for Puerto Rico (Liogier et al. 1982); also Barbados, Grand Cayman.

Number of Occurrences: 81 to >300

Overall Threat Impact Comments: Major threat is to pine rockland habitat more than to species itself. Many known populations have disappeared in past 20 years due to habitat destruction.

Intrinsic Vulnerability Comments: Very fire adapted and seems to increase in density following fires. Not affected by frost or hurricane.

Basic Description: Woody perennial shrub of hammock margins.
Habitat Comments: Most common along hammock margins in pine rocklands. Occasionally found in open pine rocklands. Most easily found 1-5 years after a fire (C.E. Hilsenbeck, pers. comm. 1995). In the Bahamas these plants are found in weedy areas, fields, rock flats, coppices, pinelands, and coastal brushlands (Correll and Correll 1982).
