(Adv. from Eu.) P. MINOR Retz. has been collected at St. John, N. B. (Fowler) and on ballast at Camden, N. J. {Pollard). The spikes are oblong and the glumes are narrowed at the pointed apex, the exposed portion of the keel being somewhat toothed. § 2. DfGRAPHIS (Trin.) Endl.

Perennial, 6-15 dm. high; leaves flat, 6-10 mm. wide; panicle 6-15 dm. long; â spikelets lanceolate, 5 mm. long, pale; sterile lemmas reduced to minute hairy scales. â Wet grounds ; common, especially northw. June, July. Fig. 76. Var. pfcxA L., the leaves striped with white, is the familiar Ribbon Grass of the garden. (Eurasia.) . arundinacea X2. Spikelet; same with glumes Sep-. arated. SO.
