---|---|---|---|---|---|
Asteraceae | Helenium amarum | Bitterweed | Roadsides, overgrazed pastures, urban areas; in much of our area an introduction from farther west. | Apparently native to e. and c. TX; now widespread in e. North America. | |
Asteraceae | Helenium autumnale | Common Sneezeweed | Moist pastures, forests, woodlands, forest edges. | QC west to BC, south to n. peninsular FL, TX, and CA. | |
Asteraceae | Helenium badium | Bason Sneezeweed | Open areas; eastwards as a waif in waste areas around a wool-combing mill (Nesom 2004d). | Native of OK, TX, and Mexico. | |
Asteraceae | Helenium brevifolium | Shortleaf Sneezeweed | Seepage bogs, river-scoured cobble bars. | H. brevifolium has a peculiar distribution, reaching its greatest abundance on the Gulf Coastal Plain, from Panhandle FL west to e. LA, and occurring at widely scattered disjunct sites in c. and n. AL, wc. GA, c. and w. NC, ec. TN (Chester, Wofford, & Kral 1997), and sw. and se. VA. | |
Asteraceae | Helenium campestre | Arkansas Sneezeweed | Prairies, streamsides, wet woodlands, fields, ditches. | N. AR south to nw. LA. | |
Asteraceae | Helenium drummondii | Fringed Sneezeweed | Ditches. | W. LA west to e. TX. Reported as well for e. LA and MS (Kartesz 2010); not so reported in Kartesz (2015, 2020). Reported for FL (without locality (Wunderlin, Hansen, & Franck 2020). | |
Asteraceae | Helenium elegans | Calcareous soils, ditches, washes, along streams; eastwards in waste areas around wool-combing mill, perhaps only a waif. | Sw. AR and s. OK south to sc. TX. See Nesom (2004d). | ||
Asteraceae | Helenium flexuosum | Southern Sneezeweed | Moist pastures, moist forests, riverbanks, wet pine rocklands (in s. FL). | S. ME west to MN, south to c. peninsular FL and TX; disjunct in s. FL. | |
Asteraceae | Helenium linifolium | Slimleaf Sneezeweed | Sandy soils, ditches, pastures. | Endemic to s. TX. | |
Asteraceae | Helenium microcephalum | Smallhead Sneezeweed | Ditches, washes, eastwards as a waif in waste areas around wool-combing mills (Nesom 2004d). | Native of OK, TX, NM, CO, and Mex. | |
Asteraceae | Helenium pinnatifidum | Savanna Sneezeweed | Wet pine savannas and adjacent ditches. | A Southeastern Coastal Plain endemic: se. NC south to s. FL, west to Panhandle FL, sw. GA, and s. AL. | |
Asteraceae | Helenium quadridentatum | Moist soils of pond edges, streambanks, and ditches. | AL west to TX, south to Mexico and Central America; Cuba. The occurrence in SC reported by Rydberg (1915), Small (1933), and Kartesz (1999) is likely an introduction. | ||
Asteraceae | Helenium vernale | Wet pine savannas and adjacent ditches. | Se. NC south to ne. FL, Panhandle FL, and west to e. LA. | ||
Asteraceae | Helenium virginicum | Virginia Sneezeweed | Seasonal sinkhole ponds and clearings where such ponds once occurred. | H. virginicum is bimodally endemic in VA (Augusta and Rockingham counties, VA, where a series of sinkhole ponds (dolines) on acid colluvium support numerous Coastal Plain disjuncts) and MO (Ozarkian highlands); also recently discovered in IN. |
