Description

Common Name: finger rot

Cnidoscolus stimulosus is a perennial herbaceous species. It tends to grow erect from a tuberous base, and is marked by the presence of urticating hairs (FSU Herbarium).

Distribution

Ecology

Habitat

Cnidoscolus stimulosus was found in sparsely canopied upland habitats that occur on deep, well drained, sandy substrate suitable for construction of Gopher tortoise burrows. Occur in dry flatwoods/sandhill.[1] Cnidoscolus stimulosus is a feature of sandhill communities with frequent occurrence in the understorey.[2]

Phenology

It has three seeds fruit and produce seeds with elaiosomes”[2]

This species was observed flowering in January, March through August, and December (FSU Herbarium). Fruiting was observed April through August and in December (FSU Herbarium).

Seed dispersal

“In all of these species, seeds are forcefully expelled after the fruit matures and dries. 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).” [2]

Seed bank and germination

Fire ecology

Are included in the flowering plant survery – post burn – in Heuberger’s study.[3] Cnidoscolus stimulosus was one of the plant species to increase in abundance recovery post-fire in Rosemary scrub ecosystem.[4]Cnidoscolus stimulosus also resprouted post-burn after fire was reinstated into the ecosystem.[5]

It resprouts and flowers within two months of burning in the growing season.KMR Overall, the species appears to be tolerant of fire, and potentially benefits from it, but it does not seem to be dependent on the presence of fire on the landscape (FSU Herbarium).

Pollination

Use by animals

“Seeds were found in middens of harvester-ant nests of Pogonomyremex badius Latreille. In addition, seeds of all three plant species were observed being carried into the ant nests and then later deposited uneaten at the nest perimeter.”[2]Gopher tortoises (juveniles and adults) feed on Cnidoscolus stimulosus.[6]Included in gopher tortoises’ scat.[7]
