Panicum implicatum of Michigan Flora.
Common and widespread, in a diversity of dry or moist open places and thickets; most often on moist sandy, calcareous, or marshy shores; also in dry oak forests, meadows, sandy barrens and jack pine plains, fields and disturbed ground, and even bog mats (very rarely).
Very variable in stature and in amount of pubescence. In the small spikelets, D. implicatum may seem close to D. meridionale, especially to specimens of the latter in which the fine secondary pubescence is obscure. On the other hand, glabrate specimens of D. implicatum do seem to grade into D. lindheimeri. Plants here treated as D. lindheimeri have the upper internodes, peduncle, and axis of panicle glabrous; the upper sheaths and blades nearly or quite glabrous; and the lower part of the plant glabrate to moderately pilose. These have sometimes been identified as a robust glabrate form of D. implicatum. As here treated, D. implicatum has more pubescence in any or all of these parts. Ordinarily, pilosity in the axis of the panicle will distinguish D. implicatum. Justin Thomas has annotated some fairly large-leaved plants, mostly from southern Michigan as D. lanuginosum (Elliott) Gould.
