Green kyllinga

摘要

Green kyllinga (Kyllinga brevifolia) is a weedy sedge that is becoming a major problem in turf and ornamental plantings in California. Green kyllinga has been reported as a weedy problem from Florida across the southeastern U. S. into Arizona and California and Hawaii. In California it has been reported in San Diego, Los Angeles, Sacramento, and in the San Joaquin and the Sacramento valleys. Due to its similarity in size and growth pattern, it is often confused with yellow or purple nutsedge. However, its fertile -globular flowers, extensive rhizomes, and absence of underground tubers make it easily distinguishable from these species.
