Rainiera is a monotypic genus of flowering plants in the daisy family, Asteraceae. The single species, Rainiera stricta(Greene) Greene, is endemic to the northwestern United States. The genus is part of the tribe Senecioneae, and appears to be most closely related to Luina, another genus of northwestern North America, in which it was once placed. Rainiera stricta is of conservation concern, with a G2G3 ranking from NatureServe, and is considered to be globally imperiled. It is known by the common name false silverback.
Symphyotrichum depauperatum, commonly known as serpentine aster or starved aster, is a rare species in the family Asteraceae adapted to serpentine barrens, an ecosystem with a high concentration of toxic metals in the soil. It has been found in Pennsylvania, Maryland, and on some diabase glades in North Carolina. It grows to 50 centimeters and has white ray florets surrounding a center of yellow disk florets.
Tradescantia ozarkana, the Ozark spiderwort, is a species of Tradescantia. It is part of the Commelinaceae family, native to the States of Missouri, Arkansas, and Oklahoma in the south-central United States. It flowers from April to May and can be found in rich, rocky areas, including woods and bluff ledges.
Cardamine angustata is a perennial forb native to the eastern United States, that produces white to pink or purple flowers in early spring.
Tradescantia longipes, commonly known as the wild crocus, is a perennial herbaceous plant in the dayflower family. It is found only in the Ozark Mountains of southern Missouri and northern Arkansas in the Midwest United States. A spring blooming species, its flowers can be observed from April to May, typically in its preferred habitat of wooded slopes on rocky hillsides. While most other members of the genus in North America have stems reaching at least a few inches above the soil, the flowering shoots of Tradescantia longipes are borne essentially at ground level. This character is shared with some individuals of Tradescantia hirsuticaulis and Tradescantia virginiana, two closely related species, although both typically have obvious stems. Regardless, Tradescantia longipes can be distinguished from the former with its longer pedicels and bracts without fine hairs, and from the latter by the presence of at least some glandular hairs on the sepals. Furthermore, Tradescantia longipes is a tetraploid, meaning it has four sets of chromosomes, while Tradescantia hirsuticaulis is diploid with only two sets. Tradescantia virginiana occurs in both diploid and tetraploid forms, although it is consistently tetraploid where its range overlaps with Trandescantia longipes.
Arisaema stewardsonii is a species of flowering plant in the arum family Araceae. It is a member of the Arisaema triphyllum complex, a group of closely related taxa in eastern North America. The specific name stewardsonii honors American botanist Stewardson Brown (1867–1921). It is commonly known as the bog Jack-in-the-pulpit. It is sometimes referred to as the swamp Jack-in-the-pulpit, not to be confused with Arisaema pusillum, which is also known by that name.
