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 maculata Commelina maculata is an herbaceous plant in the dayflower family found in India, Burma, Bhutan, and southern China. It is most often encountered along forest margins, in grasslands, along roadsides, or in moist ditches. The species is characterized by its short-stalked spathes with fused margins that usually occur in clusters of two or three, bearing flowers that barely stick out from the mouth of the spathe. The species is very similar to "Commelina paludosa", and further study is needed to recognize the boundary between the two. The two are typically differentiated on the basis of "C. paludosa" having larger and more numerous spathes that occur in clusters of four to ten, forming a sort of head. "C. paludosa" is also reported to have larger leaves, a more erect habit, less branching, and thicker stems. On the other hand, "C. maculata" is supposed to have heads of only two to three spathes, low-growing stems, numerous branches, slender stems that root at the nodes, and leaves less than ten cm long by two and a half cm wide.
