cels, oval, about 1.8 mm. long and 1.5 mm. wide, obtusely apiculate at the apex, the outer 
2 scales densely pubescent with short spreading glandular-tipped hairs, the first scale 3- 
nerved, the second usually 2-nerved by the suppression of the midnerve.

5. Paspalum stramineum Nash. Foliage light yellowish green, the spikelets, and 
sometimes also the sheaths, pale straw color. Stems tufted, 2-8 dm. tall: basal leaf-sheaths 
softly and densely pubescent, the remaining sheaths glabrous, excepting on the margins ; 
blades erect or nearly so, firm, linear to lanceolate, long-ciliate on the margins, otherwise 
glabrous except usually on the midnerve beneath, 5-25 cm. long, 5-10 mm. wide: racemes 
4-10 cm. long, on the main stem usually 2, rarely 1 or 3, single on the branches : spike- 
lets in pairs, on shorter pubescent pedicels, orbicular, 2 mm. in diameter, the first scale 
3-nerved, pubescent with short spreading glandular-tipped hairs, the second scale glabrous 
or nearly so, 2-nerved, the midnerve suppressed.

ciliate with long hairs: racemes single, or sometimes in 2’s, 5-11 cm. long: spikelets in 
pairs, 1.8-2.1 mm. long and 1.5-1.8 mm. broad, oval to broadly obovate, the 2 outer 
scales 3-nerved or the second one rarely 2-nerved by the suppression of the midnerve, 
both the scales glabrous.

or less, 4-10 mm. wide, glabrous on both surfaces, ciliate on the margins with hairs less 
than 1 mm. long: racemes single or in pairs, 2-5 em. long: spikelets about 1.6 mm. long 
and about 1.3 mm. wide, the scales glabrous, the first scale 3-nerved, the second one usu- 
ally 2-nerved by the suppression of the midnerve. 
In dry soil, Kentucky and Tennessee. Summer. 
9. Paspalum longepedunculàtum Le Conte. Stems tufted, 2.5-8 dm. tall, smooth 
and glabrous: leaf-sheaths glabrous excepting on the pilose margins, crowded towards the 
base of the stem : blades 2.5-9 cm. long, rarely a little longer, 4-9 mm. broad, smooth and 
glabrous below, pubescent above with short appressed hairs, conspicuously ciliate on the 
margins, the hairs about 2 mm. long: racemes in l's or Xs, 2.5-8 cm. long: spikelets in 
pairs, 1.5-1.8 mm. long, 1-1.2 mm. wide, broadly obovate, glabrous, the first scale 3-nerved, 
the second 2-nerved by the suppression of the midnerve which is rarely present. 
In sandy or rocky soil, Georgia and Florida. Summer and fall. 
10. Paspalum Eggértii Nash. Stems tufted, 3-5 dm. tall: basal leaf-sheaths pubes- 
cent, the remainder ciliate on the overlapping margin but otherwise glabrous ; blades lan- 
ceolate, glabrous on both surfaces and on the margins, 10 cm. long or less, 4-8 mm. wide: 
racemes single or in pairs, 4-6 cm. long: spikelets in pairs, a little exceeding 2 mm. long 
and about 1.5 mm. wide, oval, the first scale strongly pubescent with short spreading hairs, 
3-nerved, the second scale usually 2-nerved by the suppression of the midnerve, sparingly 
pubescent with similar hairs.

11. Paspalum rigidifolium Nash. Stems tufted, erect, 3-8 dm. tall, smooth and 
glabrous: basal leaf-sheaths softly pilose with rather long spreading hairs, the remaining
