From the Mediterranean region through the Old World Tropics to Australia (N.S. Wales); in Malesia with certainty only known from E. Java (Modjokerto, along Brantas R.) and the Philippines (Luzon).
There are also specimens in the Florence Herbarium from "Java, LABILLARDIERE", and in the British Museum from "Malaya; probably Borneo, LOBB" without precise localities.


MERRILL merged the Philippine collections into F. dichotoma (L.) VAHL (as F. annua R. & S.), but it is one of the best characterized species of the difficult group, readily distinguishable by its angular spikelets and membranous, acutely keeled, mucro- nulate glumes.
