Description
"Perennial or annual, erect herbs, stems erect, densely short pubescent, terete to obscurely angled, strict to freely branched. Leaves alternate, serrate, the teeth-callous-thickened, petiolate to sessile. Heads corymbose. Involucres hemispheric to campanulate, many flowered; bracts imbricate, in several series. Flowers all discoid, perfect, very small. Nutlets small, cylindric, 5-ribbed; pappus bristles whitish, capillary, minutely, antrosely barbed, 3-4 mm long." - Radford et al 1964
"Pubescent perennial, 4-11 dm tall, usually strict. Leaves oblong to elliptic-oblong, 3-9 cm long, 1.3-5 cm wide, obtuse to acute, auriculate-clasping sessile. Heads sessile or essentially so in glomerules in compact corymbs, the lateral branches usually overtopping the central. Involucres 3-6 mm long; bracts acute. Corollas pink. Nutlets black, 0.5-1 mm long, densely pubescent." - Radford et al 1964
Distribution
P. rosea is distributed in the northern and central Bahamas, North America and the Caribbean[1].
Ecology
Habitat
Habitats of P. rosea include swamp grasslands, river banks, edges of limestone sinks, and disturbed coastal prairies (Delta State University Herbarium, University of Texas Herbarium). Associated species include Sapium sebiferum, Panicum virgatum, Symphyotrichum, Ludwigia linearis, Helianthus angustifolius, Rudbeckia nitida var. texana, Paspalum floridanum, and Rhynchospora (University of Texas Herbarium).
