Introduced from Europe. 59. CiNNA L, Spikelets 1-flowered, disarticulting below the glumes, the rachilla forming a stipe below the floret and produced behind the palea as a minute bristle; glumes equal, 1-nerved; lemma similar to the glumes,. Fig. 71.—Coleanthus suitilis. Plant, X 1; lemma and palea and two views of spikelet with ripe caryopsis, X 20. nearly as long, 3-nerved, bearing a minute, short, straight awn just below the apex; palea apparently 1-nerved, 1-keeled. Tall perennial grasses, with flat blades and paniculate inflorescence. Species three, North America and northern Eurasia, two in the United States and one in Mexico and southward. Type species: Cinna arundinacea L. Cinna L., Sp. PI. 5, 1753; Gen. PI., ed. 5, 6. 1754. A single species is Abola Adans., Fam. PI. 2: ?,1, rAI. 1703. Based on "Cinna ; Ginnastrum Fourn., Mex.

The prolongation of the rachilla is less than mm. in our species, but in Ciwna 'po(juifo7''mM of Mexico it is half as long as the palea. The palea is 1-nerved in O. arundinacea. In G. poaeformis the 2 nerves are close together but distinct. In 0. latifolia the palea is apparently 1-nerved, but the 2 nerves separated when the palea is split along the Please note that these images are extracted from sca
