Taxonomic notes
Synonyms: Dalea pinnata (J.F. Gmelin) Barneby var. pinnata; Petalostemum pinnatum (J.F. Gmelin) Blake; Kuhnistera pinnata (J.F. Gmelin) Kuntze
The Latin name refers to the finely pinnate leaves.[1]
Description
Distribution
Distributed from North Carolina south to Florida and west to Louisiana.
Ecology
Habitat
D. pinnata occurs in longleaf pine-scrub oak sandhills, pine flatwoods, pine-palmetto barrens, turkey oak sand ridges, sand scrubs, lake edges, and on grassy slopes near bogs. Is also found in human disturbed areas such as roadsides, fields,and forest edges. It can grow in sand, sandy loam, and sandy clay.[2]
Associated species includes Pinus palustris, Quercus incana, Quercus laevis, Chrysopsis gossypina, Pityopsis aspera, Sorghastrum nutans, Rubus cuneifolius, Liatris gracilis, Lechea, Sericocarpus tortifolius, Solidago odora, Eupatorium album, and Trichostema dichotomum.[2]
Phenology
It has been observed flowering August to November and fruiting in October.[2]
Seed dispersal
This species disperses by gravity. [3]
Seed bank and germination
This species is capable of forming soil seed banks with seed dormancy capable of being broken through scarification. Light is not required for germination[4].
Fire ecology
It is associated with frequently burned areas[2].
Pollination
Hall and Ascher (2014) observed Trachusa fontemvitae and 9 species of Megachilidae on D. pinnata at the Ordway-Swisher Biological Station in North-Central Florida.[5]
