Description
A description of Bejaria racemosa is provided in The Flora of North America.
B. racemosa is a long live perennial shrub with leaves that are alternate, entire and coriaceous. The leaves and stems are covered with rough, firm, and stiff hairs [1]. It grows around 2 to 5 feet high and has large white flowers tinged pink. A viscid sticky substance that entraps insects is secreted on the stem below the flower (Webster 1893).
Species in the genus Bejaria have separate petals, radial symmetry, open rotate flowers, superior ovaries, and septicidal capsules; classifying them as the most primitive genus in Ericaceae (Kron 1997)
Distribution
It is a native to southeast Georgia and throughout Florida, except in the western panhandle and the keys [2].
Ecology
Habitat
In the Coastal Plain in Florida, B. racemosa has been found in pine flatwoods, scrub barrens, and sand pine scrubs (FSU Herbarium). It is drought tolerant and is found on well drained sandy soils in full sun to light shade [3]. Associated species include Callicarpa americana, Ceratiola ericoides, Rhus copallinum, slash pine, wax myrtle, and saw palmetto [2].
Phenology
Flowers are white with a pink tinge with black, sticky dehiscent fruit [2] [4]. It has been observed flowering and fruiting May through August (FSU Herbarium).
Seed bank and germination
For some species native to fire-prone habitats, chemicals in smoke may induce germination, signaling the seed that the environmental conditions are favorable for germination and growth (Lindon and Menges 2008). In a study done by Lindon and Menges (2008), they found that smoke exposure under five minutes did not effect the germination rate, however there was no germination for seeds exposed to smoke for more than five minutes.
Pollination
The following Hymenoptera families and species were observed visiting flowers of Bejaria racemosa at Archbold Biological Station (Deyrup 2015):
Apidae: Apis mellifera, Bombus impatiens, B. pennsylvanicus
Halictidae: Agapostemon splendens, Augochlorella aurata, A. gratiosa, Augochloropsis sumptuosa
Megachilidae: Anthidiellum perplexum, Anthidium maculifrons, Coelioxys sayi, Megachile brevis pseudobrevis, M. mendica, M. petulans
Vespidae: Euodynerus boscii boharti, Monobia quadridens, Parancistrocerus histrio, P. salcularis rufulus, Pseudodynerus quadrisectus, Stenodynerus fundatiformis, Zethus spinipes
