Eryngium cuneifolium is an aromatic perennial herb found on the southern Lake Wales Ridge in Highlands County, Florida. It has a long, woody taproot and a persistent rosette of dark green leaves. These leaves are long, stalked, and shaped like narrow wedges. With several erect and branching flowering stems emerging from the rosette, a plant can reach a maximum height of 0.9 m. Blooming from August to October, flowers are small with white petals, filaments, styles and stigmas and powdery-blue anthers that form small heads with bristly bracts. (USFWS 1999; FNAI 2000)
This species is threatened by the development of its habitat for housing and citrus production, as well as by fire suppression. This species thrives in the open gaps of scrub areas that would otherwise be closed canopies if not for the presence of occasional fire. (USFWS 1999; FNAI 2000)
Distribution & Occurrence
This species is found in the scrub communities of Florida's xeric uplands. (Coile 2000) It favors sunny sites of open sand or disturbed soil and most often occurs in the shrub gaps of rosemary scrub. (NatureServe 2001)

Conservation, Ecology & Research
Gravity is the only known seed-dispersal mechanism.
Pollination is likely done by generalist insects
Ceratiola ericoides may affect this species through allelopathy
(Wunderlin et al. 1981; Kral 1983; Richardson 1985)
Small number of populations on protected land, need to acquire additional sites for preservation
Controlled burning or some other mechanical disturbance needed to maintain open space for habitat
