Extended data:
Boschniakia boschniakia rossica grows on slopes, forests and low-humidity places under rivers at an altitude of 1500- 1800 meters. It is often parasitic on the roots of poplar (also known as Mu Kai). Boschniakia boschniakia exclusively parasitizes the root tip of the soil surface layer of the middle-aged or mature forest of Akagi in betulaceae. Boschniakia brasiliensis rarely grows in young and over-mature stands of Akagi, and there is no parasitic phenomenon when trees die and roots rot.
Boschniakia likes dark, humid and low temperature environmental conditions. Without such environmental conditions, there would be no distribution of Boschniakia in Populus davidiana forest. The distribution area of grass velvet has a cold climate, high relative humidity, rainy and foggy in summer, humid and cool, and the annual precipitation is1000-1400 mm.
Because there are a large number of hot springs and rivers in the distribution area, coupled with the interaction of complex topography such as mountains and deep valleys, the microclimate of hot springs and valleys with the above climatic characteristics is very suitable for the growth of grass.
