Taxonomic notes
Synonyms: none.[1]
Varieties: C. glandulosus Linnaeus var. septentrionalis Muller of Aargau.[1]
Description
This species is an annual forb/herb and subshrub that is a member of the Euphorbiaceae family.[2] Leaves alternately arranged, serrate, and lanceolate to ovate shape. Flowers unisexual and borne on a terminal raceme. Fruit type is a capsule.[3]
Distribution
Croton glandulosus is native throughout tropical and subtropical America, but its original range is obscure.[4] It is introduced as well as native in the eastern and central United States, from Pennsylvania and New Jersey south to Florida as well as west to New Mexico, Kansas, Nebraska, South Dakota, and Minnesota. The species is also native to Puerto Rico and the U.S. Virgin Islands.[2]
Ecology
Habitat
It can be found in mid-grass prairie communities.[5] It can also be found in longleaf pine communities, though it is not as common since they're dominated by perennial species.[6] This species has been observed in sandy and sandy loam soils of turkey oak ridges, open fields and clearings, wet borders of swamps, cabbage palm hammocks, dunes, and the ecotone between trees and shoreline of beaches. This species also occurs in human disturbed areas such as grassy highway medians, grassy edges of parking lots, along railroad tracks, waste areas, sandy roadsides, corn fields, and citrus groves.[7] It also is an indicator species for old-field sites.[8][9]
Associated species includes Quercus laevis, Q. geminata, Baptisia, Selaginella, Polygonella, Commelina, Pinus palustris, Haplopappus divaricatus, Pityopsis, Palofoxia, Ambrosia, and Conyza.[7]
Phenology
It is seasonal; it is mainly found from May to December, peaking in September in a study at Padre Island.[5] It has been observed flowering and fruiting June through October with peak inflorescence in June and August, and fruiting in December.[7][10]
Seed dispersal
This species is thought to be dispersed by ants and/or explosive dehiscence. [11]
Seed bank and germination
It germinates after fire.[5]
Fire ecology
It is included in the flowering plant survery – post burn – in Heuberger’s study[12]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Croton glandulosus at Archbold Biological Station: [13]
Sphecidae: Cerceris blakei, Philanthus ventilabris
Use by animals
C. glandulosus consists of approximately 5-10% of the diet for terrestrial birds.[14] It is eaten by bobwhite quail, where one study found it to be an important food source only in 1 year old Loblolly pine (Pinus taeda) plantation stands.[15]
Conservation, cultivation, and restoration
C. glandulosus is listed as threatened by the Ohio Department of Natural Resources. It is also considered a species that can be weedy or invasive by the Southern Weed Science Society.[2]
Cultural use
Many species of Croton can be used in medicine, but oil derived from the plant can be highly toxic for canines and cause blistering on skin.[16]
