Description

Distribution

Ecology

Habitat

This species is found in mesic wooded slopes of a ravine and nature parks.[2]

E. pubentissima was found to decrease its occurrence in response to soil disturbance by agriculture in southwest Georgia. It has shown resistance to regrowth in reestablished native savanna habitat that was disturbed by agricultural practices.[3] Additionally, E. pubentissima was found to be a decreaser in its long-term response following cessation of repeated soil disturbance.[4]

Phenology

E. pubentissima has been observed flowering in October, after a prescribed burn in July, at Pebble Hill Plantation, Grady County, GA by Michelle M. Smith. It has also been observed flowering in May, September, and November.[5]

Seed dispersal

This species is thought to be dispersed by ants and/or explosive dehiscence. [6]

Conservation, cultivation, and restoration

Cultural use

Members of this genus can be used as a laxative in small amounts, but an overdose can cause severe poisoning.[7]
