Description
A description of Balduina angustifolia is provided in The Flora of North America.
The genus Balduina is characterized by receptacular bractlets connected in a honeycomb like structure surrounding the achene.[1] It is a biennial species that forms a basal rosette the first year and a leafy flowering stem the second year.[2] It can grow up to 4-5 feet in height, with many side branches near the top.[3]
Distribution
Ecology
Habitat
In the Coastal Plain in Florida, B. angustifolia has been found in sand dunes; turkey oak sand ridges; pine scrubs; rosemary-oak scrubs; scrub oak-longleaf pine ridges; wiregrass/longleaf pine sandhills; pine flatwoods; bordering sidestreams; open woodlands; and xeric oak/saw palmetto scrubs.[4] There are greater populations of B. angustifolia in bare, open sands than in sites with shrubs or litter, making it a gap specialist.[5] It is early successional species and has been found to have a greater population growth in degraded scrubs compared to intact scrubs.[5] In a study conducted by Petru and Menges (2004) found that B. angustifolia responded to an experimental sand removal by elongating the flowering stems. It has been found in disturbed areas such as roadsides, highways, powerline corridors, bulldozed scrub oak ridges and clobbered slash pine forests.[4][6] Soil types include deep sand and loamy sand.[4] Associated species include Gaillardia, Pityopsis, Polygonella, Chrysoma, Ceratiola ericoides, Liatris, Leptoloma cognata, Pinus clausa, and Quercus virginiana.[4]
Sandhill and scrub habitats have a low availability of inorganic nutrients such as phosphorous causing B. angustifolia to depend on mycorrhizal fungi colonization on the taproot system.[2]
Phenology
Both the disc and ray flowers are yellow, with the ripe disc flowers forming a grey honeycomb shape seed.[3] The ripe seed can remain attached to the stem for months, allowing for favorable germination conditions in late winter and early spring.[3] It has been observed flowering August through November, with its peak inflorescence in October, and fruiting September and October.[4][7]
Fire ecology
Following a fire, the first year rosettes were unable to survive or resprout, making it a fire-sensitive biennial.[2] However, populations have been found to later re-establish on a burn site from seed.[2]
