Discussion
Anthoxanthum aristatum is native to Europe. It is now established but not common in the Flora region, being found in mesic to dry, open, disturbed habitats of western and eastern North America. North American plants belong to Anthoxanthum aristatum Boiss. subsp. aristatum, which differs from Anthoxanthum aristatum subsp. macranthum Valdes in having well-exserted awns and deeply bifid, sterile lemmas.
Hitchcock (1951) stated that another annual species of Anthoxanthum, A. gracile Biv., is occasionally cultivated for dry bouquets, but it does not appear to be widely available at present. It differs from A. aristatum in having longer (10-12 mm) spikelets and simple or sparingly branched culms.
