Sida hermaphrodita, known by the common names Virginia fanpetals and Virginia mallow, is a perennial forb native to the eastern United States, [3] which produces white flowers in summer.
The branching stem of Sida hermaphrodita is 1 to 4 meters tall, and up to 3 centimeters in diameter. The leaves are 10 to 20 centimeters long and borne on petioles. The leaves are simple, but palmately cleft into 3 to 7 lanceolate lobes. The flowers are borne in terminal clusters. Each flower has 5 petals, which are about a centimeter long. The fruit is a schizocarp that splits into segments when ripe. [4] [5]
Sida hermaphrodita has been recorded in Washington, D.C., Indiana, Kentucky, Massachusetts, Maryland, Michigan, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and the Canadian province of Ontario, although local distribution may be spotty. It is listed as an endangered species by the states of Indiana, Maryland, Tennessee, and Pennsylvania, and as a species of special concern by Kentucky. [3] In Virginia, Sida hermaphrodita grows in habitats such as sandy or rocky river shores. [6] The presence of this species is dependent on appropriate habitat, and it may be eliminated from an area by development, changes in land use, or competition with invasive species.
Recent phylogenetic research confirms that Sida hermaphrodita is not particularly closely related to other members of the genus Sida. Over the years, it has been suggested that this species might be closer related to the monotypic genus Napaea , or to Sidasodes, a genus of two species native to the Andes, however, further research has not supported either of these relationships. [7] Virginia mallow has since been formally treated as a monotypic, isolated, temperate, North American genus, Ripariosida hermaphrodita Weakley & D. B. Poind., named for its historic preference for inundated stream-beds. [8]
In Poland, Sida hermaphrodita is grown for its fiber, as a source of fodder for livestock, and as a source of nectar for beekeeping. It is currently being investigated as a source of biomass for alternative energy production purposes. [9] The results of trials in Northern Europe have demonstrated high yields, ranging from 6.7 to 16.7 oven dry metric tons per hectare (3.0 to 7.4 short ton/acre), annually, showing good properties as a feedstock for energy pellets [10]
Mertensia is a genus of flowering plants in the family Boraginaceae. They are perennial herbaceous plants with blue or sometimes white flowers that open from pink-tinged buds. Such a change in flower color is common in Boraginaceae and is caused by an increase of pH in the flower tissue. Mertensia is one of several plants that are commonly called "bluebell". In spite of their common name, the flowers are usually salverform (trumpet-shaped) rather than campanulate (bell-shaped).
Sida is a genus of flowering plants in the mallow family, Malvaceae. They are distributed in tropical and subtropical regions worldwide, especially in the Americas. Plants of the genus may be known generally as fanpetals or sidas.
Platystemon is a monotypic genus of flowering plants in the poppy family containing the single species Platystemon californicus, which is known by the common name creamcups. It is native to Oregon, California, Arizona, Utah and Baja California, and is found in open grasslands and sandy soils below 6,000 feet (1,800 m) elevation.
Reynoutria sachalinensis is a species of Fallopia native to northeastern Asia in northern Japan and the far east of Russia.
Ilex amelanchier, the swamp holly or sarvis holly, is a rare species of holly from the southeastern United States. It is a close relative of mountain holly which used to be placed in a monotypic genus Nemopanthus. Ilex amelanchier grows near water, for example on streambanks.
Stenanthium is a North American genus of flowering plants in the tribe Melanthieae of the family Melanthiaceae.
Agalinis paupercula, commonly known as the smallflower false foxglove, is a hemiparasitic annual plant native to the eastern parts of the United States and Canada. Found in open, moist areas, its purple flowers are borne on a 30-to-70-centimeter stem, and bloom in August and September. The species has often been treated as a variety of Agalinis purpurea, the purple false foxglove, and preliminary genetic evidence suggests that the two are, in fact, a single species.
Phacelia dubia is an annual forb native to the eastern United States, that produces cream colored or light blue flowers in early spring.
Sericocarpus linifolius, the narrowleaf whitetop aster or flax leaf whitetop, is a perennial forb native to the eastern United States, that produces white composite flowers in summer.
Cardamine angustata is a perennial forb native to the eastern United States, that produces white to pink or purple flowers in early spring.
Uvularia perfoliata, the perfoliate bellwort, is a perennial forb native to the eastern United States and Canada, which produces pale yellow flowers in spring.
Aureolaria virginica, the downy yellow false foxglove or downy oak leach, is a perennial forb native to the eastern United States and Canada, which produces yellow flowers in summer.
Agalinis purpurea is an annual forb native to the eastern United States and Canada, which produces purple flowers in late summer or early fall.
Agalinis tenuifolia, known by the common names common gerardia, slender false foxglove or common false foxglove, is an annual forb native to the eastern and southwestern United States, and Canada, which produces purple flowers in late summer or early fall.
Henry Hurd Rusby (1855–1940) was an American botanist, pharmacist and explorer. He discovered several new species of plants and played a significant role in founding the New York Botanical Garden and developing research and exploration programs at the institution. He helped to establish the field of economic botany, and left a collection of research and published works in botany and pharmacology.
Malaxis bayardii, or Bayard's adder's-mouth orchid, is a species of orchid native to northeastern North America. It is found from Massachusetts to North Carolina, with isolated populations in Ohio and Nova Scotia. There are historical reports of the plant formerly growing in Vermont and New Jersey, but it seems to have been extirpated in those two states It grows in dry, open woods and pine barrens at elevations of less than 600 m.
Styrax grandifolius, the bigleaf snowbell or bigleaf storax, is a plant species native to the southeastern United States, ranging from Virginia south to Florida and west to Texas and Missouri. The plant grows as a deciduous shrub or tree up to 6 metres (20 ft) high, and is most commonly found in upland forests of the southeast's piedmont. As the specific epithet suggests, the species has larger leaves than sympatric Styracaceae, with alternate, obovate leaves up to 14 cm long and 10 cm wide that are densely pubescent underneath. Flowers are borne during early summer in racemes containing up to 20 flowers.
Astranthium integrifolium, the entireleaf western daisy or eastern western-daisy, is a North American species of flowering plants in the family Asteraceae. It is native to the east-central part of the United States primarily the Cumberland Plateau and Ohio/Tennessee Valley. It is found in the States of Tennessee, Kentucky, Alabama, and Georgia, with isolated populations in Mississippi and West Virginia.
Cuscuta compacta, the compact dodder, is a parasitic plant that specializes on woody plants. This species is distributed across the Eastern and Midwestern USA, Eastern Canada, and Mexico.
Symphyotrichum shortii, commonly called Short's aster, is a species of flowering plant in the family Asteraceae. It is native to North America, where it is primarily found in interior areas east of the Mississippi River. Its natural habitat is in thin rocky soils of woodlands and thickets often around limestone bluffs. It is common throughout much of its range, although it is generally restricted to intact natural communities.
