Plant stout, 5 to II dm. or more tall, leaves linear-lanceolate, long 
tapering acuminate, 12 to 50 cm. long, 5 to 30 mm. broad: panicle 
usually strongly lobed, variable in shape, ellipsoid, cylindrical, or 
elongate-ovoid, apex blunt or tapering, 10.5 to 30 cm. or more long, 
14 to 55 mm. in diameter; lobes variable in size and length up to 
3 or 4 cm., sometimes short-pedicelled, base of panicle more or less 
open-interrupted: setae green, always noticeably longer than the 
spikelets, up to 12 mm. long: fruit yellowish to light brownish, mature 
usually straw, more or less rugulose, commonly obscurely so. 
This form passes into subvar. germanica and many specimens are 
difficult to place.
