Glechoma Tibetica
''Glechoma'' is a genus of flowering plants in the mint family, Lamiaceae, first described for modern science in 1753. It is distributed in northern Asia and Europe with a center of diversity in Asia, especially China. One species is naturalized in New Zealand and in North America.Jang, T. and S. Hong. (2010)Comparative pollen morphology of ''Glechoma'' and ''Marmoritis'' (Nepetinae, Lamiaceae).''Journal of Systematics and Evolution'' 48(6), 464-73. These plants are perennial herbs with stolons. The stems are prostrate or upright and bear leaf blades on long petioles. The inflorescences arising from the leaf axils have two to many flowers. The tubular corolla has two lobed lips, and is generally blue-violet. The genus is closely related to ''Marmoritis'' but closer still to ''Meehania'', and some species have in the past been moved between the latter genus and ''Glechoma''. ;Species: # ''Glechoma biondiana'' (Diels) C.Y.Wu & C.Chen - Gansu, Hebei, Henan, Hubei, Shaanxi, Sichuan ...

Delphinium Cashmerianum
''Delphinium'' is a genus of about 300 species of annual and perennial flowering plants in the family Ranunculaceae, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. The genus was erected by Carl Linnaeus. All members of the genus ''Delphinium'' are toxic to humans and livestock. The common name larkspur is shared between perennial ''Delphinium'' species and annual species of the genus ''Consolida''. Molecular data show that ''Consolida'', as well as another segregate genus, ''Aconitella'', are both embedded in ''Delphinium''. The genus name ''Delphinium'' derives from the Ancient Greek word () which means "dolphin", a name used in ''De Materia Medica'' for some kind of larkspur. Pedanius Dioscorides said the plant got its name because of its dolphin-shaped flowers. Habitat Species with short stems and few flowers such as ''Delphinium nuttallianum'' and ''Delphinium bicolor'' appear in habitats like prairies and the sagebrush steppe ...

Potentillas may also be called cinquefoils in English, but they have also been called five fingers and silverweeds. Some species are called tormentils, though this is often used specifically for common tormentil (''P. erecta''). Others are referred to as barren strawberries, which may also refer to '' P. sterilis'' in particular, or to the closely related ''Waldsteinia fragarioides''.

Mertensia Tibetica
''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). ''Mertensia'' is native to most of North America and to a large part of Asia from western China to northeastern Russia.Mare Nazaire, Xiao-Quan Wang, and Larry Hufford. 2014. "Geographic origins and patterns of radiation of ''Mertensia'' (Boraginaceae)". ''American Journal of Botany'' 101(1):104-118. . Its center of diversity is in the Rocky Mountains.
