1 04O A PPEND IX. 



P. 84, before No. 17, insert: 



i6a. Panicum perlongum Nash. ELONGATED PANIC-GRASS. A tufted 

 pubescent perennial. Culms 2-4 dm. tall, simple; sheaths hirsute with 

 long ascending hairs; leaves elongated, linear, erect, papillose-hispid be- 

 neath, 2-3 mm. wide, the upper one commonly 8-14 cm. long; panicle 

 much exserted, generally extending beyond the apex of the upper leaf, 

 4-6 cm. long, its branches erect or nearly so; spikelets about 3.25 mrn. 

 long and 1.5-1.75 mm. wide, pubescent with a few scattered long hairs. 

 On prairies and in dry soil, 111. to S. Dak. and the Ind. Terr. May-Aug. 

 Differs from P. linearifolium Scribn. in having larger spikelets which are 

 nearly glabrous. 



After Panicum Bicknellii Nash, insert: 



i8a. Panicum ciliatum Ell. CILIATE PANIC-GRASS. Culms tufted, 1-2.5 

 dm. tall, simple, glabrous, the axis of the panicle and its branches hirsute; 

 sheaths glabrous; leaves spreading or ascending, glabrous on both sur- 

 faces, conspicuously ciliate on the margin, usually 2-6 cm. long and 5-10 

 mm. wide; panicle 3-5 cm. long, its branches ascending; spikelets 1.8-2 

 mm. long and about I mm. wide, elliptic, pubescent with short spreading 

 hairs. In sandy soil, Va. (according to T. H. Kearney, Jr.) to Fla. and 

 Miss. May-July. The short and broad strongly ciliate leaves distinguish 

 this from P. Bicknellii Nash, and the glabrous sheaths separate it readily 

 from P. laxiftorum Lam. 



P. 85, before No. 24, insert: 



233. Panicum Yadkinense Ashe. YADKIN PANIC-GRASS. A glabrous 

 perennial. Culms single, 8-10 dm. tall, finally somewhat branched; 

 sheaths white-spotted; leaves ascending, lanceolate, acuminate, the pri- 

 mary ones 8-12 cm. long, 8-12 mm. wide; panicle 8-12 cm. long, its 

 branches long, ascending; spikelets about 2.3 mm. long and i mm. wide, 

 elliptic, acute, glabrous. In dry or sandy soil, Md. to Ga. June-Sept. 

 Differs from Panicum dichotomum L. in its taller culms, and larger leaves 

 and spikelets. 



No. 24, read " lucidum Ashe" instead of " sphagnicola Nash"; length 

 of spikelets should be 1.5-2 mm.; omit in line 7 the words "or sparsely 

 pubescent ". 



After Panicum Eatoni Nash, insert: 



273. Panicum octonodum J. G. Smith. EIGHT-JOINTED PANIC-GRASS. 

 Glabrous. Culms erect, 7-11 dm. tall, finally branched; leaves erect, firm, 

 4-1 1 cm. long, 4-8 mm. wide, lanceolate; panicle 9-13 cm. long, oblong, 

 dense, 2-4 cm. wide, its branches erect or nearly so; spikelets 1.3 mm. 

 long and about 0.8 mm. wide, glabrous, oval or nearly globular. In wet 

 places, N. J. to Ala. and Tex. May-Aug. Differs from Panicum Eatoni 

 in its smaller, nearly globular glabrous spikelets. 



P. 86, No. 35, read " unciph^llum Trin." instead of " pubescens Lam.", 

 and as a synonym add " P. pubescens A. Gray, not Lam." 



After No. 35, insert: 



35a. Panicum Tennesseense Ashe. TENNESSEE PANIC-GRASS. Culms 

 tufted, 4-6 dm. tall, rather weak and ascending, papillose-hirsute with 

 long spreading hairs; leaves ascending, lanceolate, the lower surface softly 

 and densely pubescent with short hairs, the upper surface with scattered 

 long hairs, the primary leaves 4-10 cm. long, 5-10 mm. wide, those on the 

 branches much shorter and spreading and with the upper surface nearly 

 glabrous; panicle 7-10 cm. long, its branches ascending; spikelets 1.7-2 

 mm. long, 0.8-0.9 mm. wide, elliptic or obovoid, strongly pubescent with 

 long spreading hairs. In woods, N. Y. and 111. to Tenn. and Fla. July- 

 Sept. Differs from P. unciphyllum Trin. in its lighter color, usually weak 

 culms, and the glabrous upper surface of the leaves.
