Description

A description of Balduina angustifolia is provided in The Flora of North America.

Ecology

Habitat

In the Coastal Plain in Florida, B. angustifolia has been found in sand dunes; turkey oak sand ridges; pine scrubs; rosemary-oak scrub sandridge; scrub oak-longleaf pine ridges; wiregrass/longleaf pine sandhills; pine flatwoods; bordering sidestreams; open woodlands; and xeric oak/saw palmetto scrubs (FSU Herbarium).There are greater populations of B. angustifolia in bare, open sands than in sites with shrubs or litter, making it a gap specialist (Stephens et al. 2013). It is early successional species and has been found to have a greater population growth in degraded scrubs compared to intact scrubs (Stephens et al. 2013). It has been found in disturbed areas such as roadsides, highways, powerline corridors, bulldozed scrub oak ridges and clobbered slash pine forest (FSU Herbarium). Soil types include deep sand and loamy sand (FSU Herbarium). Associated species include Gaillardia, Pityopsis, Polygonella, Chrysoma, Ceratiola ericoides, Liatris, Leptoloma cognatum, Pinus clausa, and Quercus virginiana (FSU Herbarium).

Phenology

It has been observed flowering August through November and fruiting September and October (FSU Herbarium).
