Description

Distribution

Ecology

Habitat

It is extremely vulnerable to disturbance. One reason for this might be that it relies too much on native species of ants for dispersal.[1] It can be found in longleaf pine communities.[2] It can also be found in sandhill communities.[3] It has been found on the edges of sandy oak-palmetto scrub, clobbered, cutover flatwoods, and pine-turkey oak flatwoods and sand ridges[4]. It has also been found to grow along disturbed areas like the wooded edges of powerline corridors. Growing in either moderate shade to full sun, this species grows in drying sandy loam in the uplands.

Associated species includes Crotonopsis, Paronychia, Tetragonotheca, Berlandiera, and Onosmodium[4].

Phenology

It is a summer forb.[1] This species has been observed to flower from April to October and to fruit from April to September (FSU Herbarium).

Seed dispersal

Seeds have elaiosomes, and can be dispersed by ants such as fire ants (Cumberland et al 2013). It can also be dispersed explosively (Kirkman et al 2004). Three of the ballistic euphorbs (C. stimulosus, C. argyranthemus and S. sylvatica) produce seeds with elaiosomes and all of the ballistic species are collected by ants, in particular Pogonomyrex badius Latreille (Long and Lakela 1971; N.E. Stamp and J. R. Lucas, personal observation).”[3] According to Kay Kirkman, a plant ecologist, this species disperses by explosion mechanisms or by ants. [5]

Fire ecology

This species is fire tolerant and is included in the flowering plant survery – post burn – in Heuberger’s study.[6]

Use by animals

Ants are an agent of seed dispersal (Cumberland et al 2013). C. argyranthemus is an important game food plant: it is consumed by doves, quail, and deer.[7]
