This native perennial has erect or nodding flower stems from 2-3 feet tall. The flat, relatively short 3-8 inch leaves are broadest near the base, tapering slowly to a bluntly pointed tip (A). Most leaves come off one side of the stem and project out stiffly at a 90 degree angle, giving individual plants a “windblown” look (C). Cross-veins can be seen between the main parallel veins when transilluminated or backlit by the sun (D). The flower cluster is a narrow, closed panicle from 3-6 inches long bearing slender 1/2 inch florets each with an awn that is usually longer than the floret (E). In mature plants the panicle may open up a bit making the individual branches more obvious (F).

Moist upland woods. This plant, although common in a number of areas on Prairie, History and Oak Trails, is rare on the trails that are closer to the Buffett Learning Center. A few plants are present on Ridge and Chickadee Trails. To date it has only been found at Fontenelle Forest.

 

Another superficially similar plant of the upland woods, Black-seed Ricegrass (Piptatherum racemosum), has an open panicle and longer arching leaves which do not have cross veins. The cross-veins are unique to Bearded Wood Grass and are not present in any other grass at Fontenelle Forest or Neale Woods.
