In between Luzula and Patrinia which has 17 species native to grassy mountain habitats in China, Siberia and Japan?
Luzula 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.
Commelina communis Commelina communis, commonly known as the Asiatic dayflower, is an herbaceous annual plant in the dayflower family. It gets its name because the blooms last for only one day. It is native throughout much of East Asia and northern parts of Southeast Asia. In China, the plant is k nown as yazhicao (), roughly translating to "duckfoot herb", while in Japan it is known as tsuyukusa (露草 , tsuyukusa ) , meaning "dew herb". It has also been introduced to parts of central and southeastern Europe and much of eastern North America, where it has spread to become a noxious weed. It is common in disturbed sites and in moist soil. The flowers emerge from summer through fall and are distinctive with two relatively large blue petals and one very reduced white petal.
