FURTHER INF Scientific synonyms: I. arundinacea, I. cylindrica var. major, Lagurus cylindricus. Blady grass has a latitudinal distribution between 45°N and 45°S. It can be found at elevations between sea level and 2000 m in the Himalaya and it is common in subhumid and humid grassland and open woodland. It is quite drought resistant but will not tolerate long periods of flooding. Frequent fires encourage the growth and uniformity of the sward. It has a deeply buried aggressive rhizome, that can penetrate the roots of other plants, causing rot or death. Dry matter yields may be between 2-12 t/ha.
