Comments: Variety fasciculatum is the most common and widespread variety of Dichanthelium acuminatum.  The Flora of North America describes this variety as highly variable and difficult to distinguish from other small stature varieties such as Dichanthelium acuminatum avr. implicatum.  One useful character to use for varietal separation is the width of the cauline (>6mm) leaves and shorter hair (<3mm) on the upper leaf surface.
