Blue panicum

Janochloa antidotalis (Punjabi: ਘਮੂਰ ghamur, English: blue panicgrass, synonym Panicum antidotale) is a species of grass. it is the sole species in genus Janochloa. It is a tall (up to 3 metres), coarse, woody perennial grass strong spreading rhizomes. It is native to southern Asia, ranging from the Sinai Peninsula through the Arabian Peninsula, Iran, Transcaucasia, the Indian Subcontinent, and Myanmar to Vietnam. In the Indian Subcontinent it is found in the Himalaya and the Upper Gangetic Plain and specifically in various regions of the Indian state of Punjab and the Pakistan province of Punjab and the neighbouring areas of these regions.

This grass is also listed (as Panicum antidotale) by William Coldstream in his Illustrations of Some of the Grasses of the Southern Punjab with the vernacular name ghirri (Punjabi ਘਿੱਰੀ) which he however explains is not known to those landowners that he had interviewed as a separate species of Panicum but rather as an unripe form of Panicum antidotale which is generally called in Punjabi ghamur (ਘਮੂਰ).
