Taxonomic notes

Synonyms: Dalea pinnata (J.F. Gmelin) Barneby var. pinnata; Petalostemum pinnatum (J.F. Gmelin) Blake; Kuhnistera pinnata (J.F. Gmelin) Kuntze

Variety: Dalea pinnata (J.F. Gmelin) Barneby var. trifoliata (Chapman) Barneby

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] It was found to be among the most cold-hardy legumes found in southern Georgia, where it persists through repeated frosts and was present in January and February field surveys.[3]

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. [4]

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[5].

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.[6]

Conservation and management

Cultivation and restoration
