Anemone is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are commonly called windflowers. They are native to the temperate and subtropical regions of all continents except Australia and Antarctica. The genus is closely related to several other genera including Anemonoides, Anemonastrum, Hepatica, and Pulsatilla. Some botanists include these genera within Anemone.

It is a widespread North American violet found in rich, mesic woodlands, and sometimes in meadows, from Minnesota and Ontario east to Nova Scotia and south to Virginia. V. pubescens produces two different types of flowers during the season, including chasmogamous flowers in the early spring and cleistogamous flowers summer through fall.
Viola hederacea, the Australian violet, is a species of flowering plant in the family Violaceae, native to Australia.
Viola sororia, known commonly as the common blue violet, is a short-stemmed herbaceous perennial plant that is native to eastern North America. It is known by a number of common names, including common meadow violet, purple violet, woolly blue violet, hooded violet, and wood violet. Its cultivar 'Albiflora' has gained the Royal Horticultural Society's Award of Garden Merit.
Coreopsis palmata is a North American species of flowering plant in the aster family native to North America.
Cucurbita palmata is a species of flowering plant in the squash family known by the common names coyote melon and coyote gourd. It is similar to Cucurbita californica, Cucurbita cordata, Cucurbita cylindrata, and Cucurbita digitata and all these species hybridize readily. It was first identified by Sereno Watson in 1876. These species form the only restricted xerophyte species group in the genus Cucurbita. Each member of this species group is native to the Southwestern United States and Northwestern Mexico where they are relatively uncommon. Each group member is found in hot, arid regions with low rainfall. They prefer soil that is loose, gravelly, and well-drained. C. palmata is native to northeastern Baja California, southeastern California, and southwestern Arizona to a point near the Colorado River. The juvenile leaves of C. cylindrata, C. cordata, C. digitata, and C. palmata show a high degree of similarity, but their mature leaves are visibly different, as are their root structures. C. palmata and C. digitata are sympatric, with C. palmata separating the ranges of C. digitata at the juncture of Baja California, California, and Arizona. C. palmata fruits are diffuse green mottle that turns yellow at maturity, striped, and round.
Cucurbita digitata is a species of flowering plant in the squash family known by the common names fingerleaf gourd and bitter squash. It is similar to Cucurbita californica, Cucurbita cordata, Cucurbita cylindrata, and Cucurbita palmata and all these species hybridize readily. These species form the only restricted xerophyte species group in the genus Cucurbita. Each member of this species group is native to the Southwestern United States and Northwestern Mexico where they are relatively uncommon. Each group member is found in hot, arid regions with low rainfall. They prefer soil that is loose, gravelly, and well-drained. C. digitata is native to northern Baja California at higher elevations, northern Sonora, Mexico, southern Arizona, and southwestern New Mexico. The juvenile leaves of C. cylindrata, C. cordata, C. digitata, and C. palmata show a high degree of similarity, but their mature leaves are visibly different, as are their root structures. C. palmata and C. digitata are sympatric, with C. palmata separating the ranges of C. digitata at the juncture of Baja California, California, and Arizona. C. digitata fruits are clear green mottle that turns yellow at maturity, striped, and round.
Viola labradorica, commonly known as alpine violet, American dog violet, dog violet, and Labrador violet, is a perennial. It is native to Greenland, eastern Canada, and the eastern United States. The plant sold as Viola labradorica by nurseries is Viola riviniana.
Viola blanda, commonly called the sweet white violet, is a flowering perennial plant in the Violet family (Violaceae). It is native to parts of south-eastern and south-central Canada and the eastern, and north-central, United States. Its natural habitat is in cool, mesic forests.
Viola pedatifida, known variously as prairie violet, crow-foot violet, larkspur violet, purple prairie violet, and coastal violet, is a perennial herbaceous plant in the Violet family (Violaceae). It is native to Canada and the United States.
Viola selkirkii is a species of violet known by the common names Selkirk's violet and great-spur violet. It is native throughout the Northern Hemisphere, its distribution circumboreal.
Cucurbita cordata is a species of flowering plant in the squash family. It is similar to Cucurbita californica, Cucurbita cylindrata, Cucurbita digitata, and Cucurbita palmata and all these species hybridize readily. These species form the only restricted xerophyte species group in the genus Cucurbita. Each member of this species group is native to the Southwestern United States and Northwestern Mexico where they are relatively uncommon. Each group member is found in hot, arid regions with low rainfall. They prefer soil that is loose, gravelly, and well-drained. C. cordata is found only in the vicinity of Bahía de los Ángeles, Baja California. Botanists Bemis and Whitaker suggest that C. cordata and C. cylindrata may be a case of sympatric speciation. The juvenile leaves of C. cylindrata, C. cordata, C. digitata, and C. palmata show a high degree of similarity, but their mature leaves are visibly different, as are their root structures. C. cordata fruits are gray green, striped, and round.
Viola walteri, the prostrate blue violet, is a perennial plant in the violet family (Violaceae). It is native to Southeastern and Appalachian North America. It is generally uncommon throughout its range, with populations becoming fragmented in the north. Viola walteri is found in rich calcareous forests and woodlands, often in dry rocky areas. It is a spring ephemeral, flowering March through May. It distinguished by its creeping, rooting stolons, which is thought to be indicative of it being transitional between the caulescent and acaulescent violets.
Viola calcarata is a species of genus Viola that grows on mountains of south-eastern Europe. It is commonly known as long-spurred violet or mountain violet. It is a herbaceous flowering perennial plant.
Viola primulifolia, commonly called the primrose-leaf violet, is a species of flowering plant in the violet family. It is native to eastern North America, and possibly also to the Pacific Northwest. Its natural habitat is wet acidic areas that are usually at least semi-open.
Viola sagittata, commonly called the arrowleaf violet, is a species of flowering plant in the violet family (Violaceae). It is native to the eastern North America in Canada and the United States, where it is widespread. It is found in a variety of natural habitats, but is most common in dry, open communities such as prairies, glades, or woodlands, often in sandy or rocky soil.
