Leptidea morsei (Fenton’s wood white) is a butterfly of the Pieridae family.
 It is found from central Europe to Siberia, Ussuri, Korea, northern China and Japan.
 The habitat consists of damp, grassy vegetation at the sunny edges of woods, in grassy woodland clearings and on regenerating woodland on grassland.
 They occur almost exclusively in oak forest and mixed deciduous woods.
Melica pappiana is a species of grass in the Poaceae family that can be found in Chinese provinces such as Jilin and Shanxi in grassy mountain slopes and forests that are full with "Larch" species on the elevation of 500 – .
Ligularia sibirica is the type species for the genus "Ligularia".
 It is a 0.3-1.3 m tall perennial herbaceous plant, native to fens and damp grassy meadows in Siberia, Central and Eastern Europe.
 Once fairly common, it has disappeared from many places in Europe, owing to drainage of wetlands and competition from other plants invading its natural habitats; when growing in shade plants do not flower or set seed very well and seed germination is greatly reduced.
 This species is sometimes grown in gardens for its large leaves and tall spike like arrangement of yellow daisy like flowers.
Luzula is a genus of flowering plants the family Juncaceae, the rushes.
 The genus has a cosmopolitan distribution, with species occurring throughout the world, especially in temperate regions, the Arctic, and higher elevation areas in the tropics.
 Plants of the genus are known commonly as wood-rush, wood rush, or woodrush.
 Possible origins of the genus name include the Italian "lucciola" ("to shine, sparkle") or the Latin "luzulae" or "luxulae", from "lux" ("light"), inspired by the way the plants sparkle when wet with dew.
 Another etymology sometimes given is that it does derive from lucciola but that this meant a midsummerfield, or from the Latin luculus, meaning a small place; the same source also states that this name was applied by Luigi Anguillara (an Italian botanist) in 1561.
Patrinia is a genus of herbaceous plants in the honeysuckle family.
 There are about 17 species native to grassy mountain habitats in China, Siberia and Japan.
 These are unassuming clump-forming perennial plants having thin, erect stems with few leaves and bearing a terminal inflorescence with yellow or white flowers.
 The use for this plant is to provide a flower through long hot summers.
Melica radula is a species of grass in the Poaceae family that can be found in Chinese provinces such as Jilin, Lea and Shanxi in grassy mountain slopes and forests that are full with "Larch" species on the elevation of 300 – .
Cardamine oligosperma is a species of cardamine known by the common name little western bittercress.
 It is native to western North America from Alaska to California to Colorado, where it grows in moist mountain habitats.
The huayco tinamou ("Rhynchotus maculicollis"), also known as "waypu" (Quechua) (also spelled "guaipo", "huaipo", "guaypo", "waypo", a name which is also applied for other "Tinamidae" species), is a species of bird found on grassy mountain ridges in the Andes of Bolivia and Argentina.
Caltha leptosepala (White Marsh Marigold, Twinflowered Marsh Marigold, or Broadleaved Marsh Marigold) is a species of flowering plant in the buttercup family.
 It is native to western North America from Alaska to New Mexico, where it grows in wet mountain habitats in alpine and subalpine regions.
 There are two general wild types of this species, one native to the interior and one that grows along the Pacific coast and coastal mountains, but these are not always treated separately.
Micranthes integrifolia is a species of saxifrage known by the common name wholeleaf saxifrage.
 It is native to western North America from British Columbia to Montana and northern California, where it grows in moist habitat, including meadows, prairies, and grassy mountain slopes.
 It is a perennial herb growing from a caudex and system of rhizomes, and producing a basal rosette of leaves.
 Each leaf is up to 7 centimeters long with a toothed or smooth-edged blade borne on a short petiole.
 The inflorescence arises on a stout, hairy peduncle up to 35 centimeters tall.
 White-petaled flowers occur in a cluster or dense array at the top.
