Taxonomic notes

Synonym: T. betonicaefolia Nuttall.[1]





In the Coastal Plain in Florida and Georgia, T. smallii can be found in recently burned scrubs, scrub oak-wiregrass communities, wiregrass-pine flatwoods, longleaf pine/wiregrass/scrub oak sandhills, recently burned longleaf pine/wiregrass communities, pine savannas, and around ephemeral ponds.[2][3] It can also be found along old logging roads, recreation areas, and bulldozed wiregrass-pinewoods. Soil types include loamy sand, sand, sandy loam, and loamy soil.[2] T. smallii had variable changes in frequency and density in response to roller chopping in northwest Florida sandhills. It either decreased its occurrence or was unaffected by this practice.[4]

Associated species include Liatris, Panicum, Leptoloma cognata, Sphenopholis nitida, Euphorbia inundata, Paspalum, Rhynchospora, Macbridea, and Justicia crassifolia.[2]

Tragia smallii is an indicator species for the Panhandle Silty Longleaf Woodlands community type as described in Carr et al. (2010).[5]


T. smallii has been observed flowering April through October and fruiting April through August.[6]

Seed dispersal

This species is thought to be dispersed by ants and/or explosive dehiscence.[7]

Fire ecology

Populations of Tragia smallii have been known to persist through repeated annual burns.[8] Tragia smallii was found frequently on plots in the Kisatchie National Forest burned 20 times each in March and July from 1962 to 1998, but rarely on plots burned in May.[3]
