Taxonomic notes

Variety: Berlandiera pumila (Michaux) Nuttall var. pumila

Named for the French-Swiss physician Jean Louis Berlandier (1805-1851) who collected plants in Texas and northern Mexico.[1]

There are two subspecies. B. pumila pumila has a spotty distribution along the coastal states from North Carolina to eastern Texas, including north Florida. B. pumila scabrella occurs only in far eastern Texas and Louisiana.[2]

Description

A description of Berlandiera pumila is provided in The Flora of North America.

Distribution

Distributed North Carolina west to east central Texas.[3]

Ecology

Habitat

B. pumila is found in longleaf pine-wiregrass sandhill communities, turkey oak hardwood sand ridges, and the borders between sandhills and hammocks. It is also found in disturbed areas including roadsides and clear-cut pine stands. This species generally prefers to grow in sandy soil types like drying loamy sand.[4]

Associated species includes Baptisia laceolata, Eupatorium capillifolium, Pinus palustris, Quercus laevis, Q. geminata, Q. laurifolia, Q. margaretta, Vaccinium arboretum, Sericocarpus tortifolius, Smilax auriculata, Polypremum procumbens, Serenoa repens, Rhus copallina, and others.[4]

Phenology

B. pumila flowers have yellow ray flowers, green disc flowers and an inferior ovary.[5] It has been observed flowering February through September, with peak inflorescence in April and May.[4][6] Fruit is a blackish achene.

Fire ecology

It thrives in landscapes that experience frequent fire. Fire clears out the mid-canopy species which can shade and reduce diversity of the groundcover. It is adapted to surviving and returning after fire.[2]
