Description
A description of Baccharis halimifolia is provided in The Flora of North America.
Baccharis genus are dioecious, glabrous shrubs. They are rarely small trees. The leaves are alternate, fleshy, toothed or entire. The heads pedunculated or sessile, most of the time in 3-5 glomerules. The involucres are cylindric, 4-5 mm long, 2.5-3.5 mm broad. The bracts are imbricate, sometimes purplish in color, and obtuse. The flowers are discoid and yellowish in color. The nutlets are tan in color, lustrous, cylindric, 10-ribbed, glabrous, and 1.2-1.5 mm long. The pappus bristles are white to tan in color. The capillary is 7-10 mm long.[1] Specifically for B. halimifolia, is a shrub, growing to approximately 1-4 m tall. The leaves are elliptic to obovate, rarely ovate; are coarsely serrate but mostly towards the apex, rarely entire. The leaves grow 3-7 cm long and 1-4 cm wide. The petioles are 5-12 mm long. The involucres are mostly in pedunculated glomerules. [1]
Distribution
B. halimifolia is native to the southeastern United States, from Texas to Virginia, and portions of the northeast including New York and Massachusetts.[2]
Ecology
Habitat
It is native to brackish and fresh marshes and marsh borders, moist abused land, ditches, roadsides and other disturbed areas, and hammocks.[3] It has also been observed in dry open slopes, moist loamy sand and loamy clay sand, shrub thickets, flatwoods, swamps, floodplain forests, and shores.[4]
Associated species: Panicum virgatum, Juncus roemerianus, Solidago sempervirens, Myrica sp., Iva sp., Hudsonia sp., Fimbristylis sp., Spartina sp., Ilex opaca, Rhus copallina, Bidens sp., Polygonum sp., Cyperus sp., Ludwigia sp., and Baccharis angustifolia.[4]
Phenology
B. halimifolia has been observed to flower in February and between September to December.[5]
Seed dispersal
This species is thought to be dispersed by wind. [6]
Fire ecology
It was observed in a burned over wiregrass, slash pine, and Magnolia virginiana bay.[4]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Baccharis halimifolia' at Archbold Biological Station. [7]
Apidae: Apis mellifera
Apidae: Bombus impatiens
Colletidae: Colletes mandibularis, C. simulans, C. thysanellae
Halictidae: Agapostemon splendens, Augochlora pura, Augochlorella aurata, Augochloropsis metallica, Halictus poeyi, Lasioglossum miniatulus, L. nymphalis, L. puteulanum, Sphecodes heraclei
Leucospidae: Leucospis affinis
Leucospididae: Leucospis affinis, L. robertsoni, L. slossonae
Pompilidae: Anoplius atramentaius, A. parsoni, Episyron conterminus posterus, Poecilopompilus algidus, P. interruptus
Sphecidae: Bicyrtes quadrifasciata, Cerceris blakei, C. flavofasciata floridensis, C. tolteca, Ectemnius decemmaculatus tequesta, E. rufipes ais, Larra bicolor, Oxybelus decorosum, O. laetus fulvipes, Palmodes dimidiatus, Philanthus ventilabris, Tachytes distinctus, T. floridanus, T. pepticus, T. validus
Vespidae: Pachodynerus erynnis, Parancistrocerus salcularis rufulus, Polistes bellicosus, P. dorsalis hunteri, P. fuscatus, P. metricus, P. perplexus, Stenodynerus beameri, S. fundatiformis, S. lineatifrons, Vespula squamosa, Zethus slossonae, Zethus spinipes
Use by animals
While the leaves on this plant are poisonous to livestock, marsh wrens and small birds use the openly branched and brittle stems for nests. The baccharis foliage feeding beetle (Trirhabda baccharidis) is a well known beetle to help keep Baccharis populations in check.[8] As well, it consists of 2-5% of the diet of large mammals and terrestrial birds.[9]
Conservation and management
It is listed as rare by the Pennsylvania Department of Conservation and Natural Resources.[2]
