Eryngium cuneifolium is a rare species of flowering plant in the carrot family known by the common names wedgeleaf eryngo, wedge-leaved button-snakeroot, and simply snakeroot.

[2] It is one of many rare species that can be found only on the Lake Wales Ridge, an area of high endemism.

[2] Other plants in the habitat include silk bay (Persea humilis), scrub palmetto (Sabal etonia), eastern prickly pear (Opuntia humifusa), and several species of oak.

In many areas, including some of the protected regions, the land is not properly managed to maintain the natural habitat.

This snakeroot, for example, requires periodic disturbance such as fire to clear out tall and woody vegetation that grows up around it and blocks the sun.

This species also needs fire in order to germinate, because excessive leaf litter and lichen cover on the ground inhibit this process.

[2][7] During fire, the plant is destroyed, but its soil seed bank is exposed for germination, and many seedlings occur.
