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.[2]
Balduina angustifolia, specifically, is a biennial species that forms a basal rosette the first year and a leafy flowering stem the second year[3]. The plant can grow up to 4 - 5 feet in height with many side branches near the top[4], and it does not have specialized underground storage units apart from its fibrous roots.[5] Diaz-Toribio and Putz (2021) recorded this species to have a water content of 65.5% (ranking 46 out of 100 species studied).[5]
Distribution
The Balduina genera is endemic to the longleaf pine range from southeastern Virginia to central Florida and west to southeast Texas.[6]
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.[7] There are larger populations of B. angustifolia in bare, open sands than in sites with shrubs or litter, making it a gap specialist.[8]
This plant is early successional species and has been found to have a greater population growth in degraded scrubs compared to intact scrubs.[8] In a study conducted by Petru and Menges (2004) found that B. angustifolia responded to an experimental sand removal by elongating the flowering stems.[7][9] 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.[3] As a result of colonizing low nutrient distrubed areas, B. augustifolia can be found in disturbed areas such as roadsides, highways, powerline corridors, bulldozed scrub oak ridges and clobbered slash pine forests.[7][9] Soil types include deep sand and loamy sand.[7]
Balduina angustifolia is an indicator species for the Peninsula Xeric Sandhills community type as described in Carr et al. (2010).[10]
Associated species include Gaillardia, Pityopsis, Polygonella, Chrysoma, Ceratiola ericoides, Liatris, Leptoloma cognata, Pinus clausa, and Quercus virginiana.[7]
Phenology
Both the disc and ray flowers are yellow, with the ripe disc flowers forming a grey honeycomb shape seed.[4] The ripe seed can remain attached to the stem for months, allowing for favorable germination conditions in late winter and early spring.[4] It has been observed flowering August through November, with its peak inflorescence in October, and fruiting September and October.[7][11]
Fire ecology
Following a fire, the first year rosettes were unable to survive or resprout, making it a fire-sensitive biennial.[3] However, populations have been found to later re-establish on a burn site from seed.[3]
Pollination and use by animals
Balduina angustifolia has been observed at the Archbold Biological Station to be visited by ground-nesting bees such as Andrena fulvipennis (family Andrenidae), bees from the Apidae family such as Apis mellifera, Bombus impatiens, B. pennsylvanicus, Nomada fervida, Svastra aegis and Triepiolus concavus, sweat bees from the Halictidae family such as Agapostemon splendens, Augochlora pura, Augochlorella aurata, Augochloropsis metallica, A. sumptuosa, Dieunomia heteropoda, Halictus poeyi, Lasioglossum coreopsis, L. miniatulus, L. nymphalis. L. pectoralis and L. puteulanum, leafcutting bees from the Megachilidae family such as Anthidiellum perplexum, Coelioxys dolichos, C. germana, C. mexicana, C. modesta, C. sayi, C. texana, Dolichostelis louisae, Megachile albitarsis, M. pseudobrevis, M. georgica, M. inimica, M. mendica, M. petulans, M. policaris, M. pruina, M. texana, M. xylocopoides and Trachusa fontemvitae, thread-waisted wasps from the Sphecidae family such as Bembix sayi, Bicyrtes capnoptera, Ectemnius rufipes ais and Philanthus ventilabris, and wasps from the Vespidae family such as Mischocyttarus cubensis, Pachodynerus erynnis and Zethus slossonae.[12] Additionally, this species has been observed with ground-nesting bees from the Andrenidae family such as Perdita bequaerti and P. consobrina, as well as the bee Svastra aegis (family Apidae), platerer bees such as Colletes thysanellae (family Colletidae), and bees from the Melittidae family such as Hesperapis oraria.[13]
It is common in areas of soil disturbance produced by gopher tortoises.[3]
