Symphyotrichum (/ˌsɪmfaɪəˈtrɪkəm/) is a genus of about 90 species of herbaceous annual and perennial plants in the composite family (Asteraceae) that were formerly treated within the genus Aster. The majority are endemic to North America, but several species also occur in the West Indies, Central and South America, as well as in eastern Eurasia. Many species have been introduced to Europe as garden specimens, most notably the New England aster (Symphyotrichum novae-angliae
The Russulaceae are a diverse family of fungi in the order Russulales, with roughly 1,900 known species and a worldwide distribution. They comprise the brittlegills and the milk-caps, well-known mushroom-forming fungi that include some edible species. These gilled mushrooms are characterised by the brittle flesh of their fruitbodies.

Neotibicen auletes commonly, but informally called the Northern dusk-singing cicada, Giant oak cicada, or Southern oak cicada, is a large bodied annual cicada which occurs in the eastern, central, and southern United States as well as southern Canada. This cicada is the largest cicada in the genus Neotibicen and the largest cicada in North America, north of Mexico. Despite its frequently used common name, this cicada is most abundantly found in the south.
Around 750 worldwide species of ectomycorrhizal mushrooms compose the genus Russula. They are typically common, fairly large, and brightly colored – making them one of the most recognizable genera among mycologists and mushroom collectors. Their distinguishing characteristics include usually brightly coloured caps, a white to dark yellow spore print, brittle, attached gills, an absence of latex, and absence of partial veil or volva tissue on the stem. Microscopically, the genus is c
Xerocomellus chrysenteron, formerly known as Boletus chrysenteron or Xerocomus chrysenteron, is a small, edible, wild mushroom in the family Boletaceae. These mushrooms have tubes and pores instead of gills beneath their caps. It is commonly known as the red cracking bolete.
Willows, also called sallows, and osiers, form the genus Salix, around 400 species of deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions of the Northern Hemisphere. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English sealh, related to the Latin word salix, willow). Some willows (particu
Lycopus uniflorus is a species of flowering plant in the mint family known by the common name northern bugleweed. It is native to much of North America (Canada, United States) and east Asia (China, Japan, Korea, Russian Far East)
Rosa multiflora (syn. Rosa polyantha) is a species of rose known commonly as multiflora rose, baby rose, Japanese rose, many-flowered rose, seven-sisters rose, and Eijitsu rose. It is native to eastern Asia, in China, Japan and Korea.

Honeysuckles (Lonicera, /lɒˈnɪsərə/; syn. Caprifolium Mill.) are arching shrubs or twining bines in the family Caprifoliaceae, native to the Northern Hemisphere. Approximately 180 species of honeysuckle have been identified. About 100 of these species can be found in China and approximately 20 native species have been identified in Europe, 20 in India, and 20 in North America. Widely known species include Lonicera periclymenum (honeysuckle or woodbine), Lonicera jap
Sanicula canadensis, the Canadian blacksnakeroot, is a native plant of North America and a member of family Apiaceae. It is biennial or periennial, and spreads primarily by seed. It grows from 1 to 4.5 feet tall, and is found in mesic deciduous woodlands. The whitish-green flowers with sepals longer than petals, appearing late spring or early summer and lasting for approximately three weeks, are green and bur-like. The bur-like fruit each split into 2 seeds. The…
Cystopteris is a genus of ferns in the family Cystopteridaceae. These are known generally as bladderferns or fragile ferns. They are found in temperate areas worldwide. This is a very diverse genus and within a species individuals can look quite different, especially in harsh environments where they experience stress and remain small and stunted. Also, they hybridize easily with each other. Identifying an individual can be challenging. In general these are rhizomatous
