NORTHERN PANIC GRASS
A. A. Reznicek
Panicum boreale of Michigan Flora.
Usually in moist to marshy sandy or rocky open ground; occasionally in dry, open aspen or oak forest.
Usually easily distinguished by glabrous foliage and nodes, at least above, and the short ligule. Some plants have the leaves ± pilose and the nodes, especially the lower ones, pilose. Stephenson (1984) considered plants called Panicum calliphyllum (see Michigan Flora) to be hybrids, and Freckmann & Lelong (2003) suggested D. boreale and D. xanthophysum as parents. We agree, and perhaps other hybrid combinations, such as D. linearifolium × D. latifolium or D. xanthophysum also account for plants with this morphology in Michigan.
