IO58 APPENDIX. 



5b. Paspalum australe Nash. Southern Paspalum. Culms tufted, 

 4-7 dm. tall; sheaths usually hirsute only on the margins; leaves erect, 

 short, commonly 1.5 dm. long or less, 5-10 mm. wide, strongly ribbed, 

 rather thick, firm, glabrous beneath or nearly so, hirsute above; racemes 

 2-5, finally spreading, usually 5 cm. long or less; spikelets singly dis- 

 posed, oval, 2.7-3 mm - l° n S an d about 2 mm. wide, glabrous. On 

 grassy flats and banks, Va. to Fla. and Ala. Aug. and Sept. Differs from 

 P. lacve and P. angustifolium by its hairy sheaths, and from the latter also 

 by its short leaves. Type collected by Dr. J. K. Small, at Stone Mt., Ga., 

 Aug. 1-6, 1895. 



P. 73, after Paspalum circulare Nash, insert: 



6a. Paspalum Boscianum Fluegge. Bosc's Paspalum. Culms 5-12 

 dm. long, compressed, finally branched, often decumbent at the base and 

 rooting at the lower nodes; sheaths compressed, glabrous, or the basal 

 ones papillose-hirsute; leaves 4-30 cm. long, 3-10 mm. wide, hairy above 

 near the base; racemes 2-13, spreading or ascending, 4-9 cm. long, the 

 rachis broadly winged; spikelets in pairs, and often so crowded as to ap- 

 pear in 4 rows, frequently reddish brown, broadly obovate, 2-2.3 mm. 

 long, 1. 5-1.8 mm. broad, the flowering scale deep brown at maturity. In 

 meadows and moist places, Va. (according to T. H. Kearney, Jr.) to Fla. 

 and Miss. Aug.-Oct. Differs from P. lacve and its relatives in having 

 the spikelets in pairs and the flowering scale a deep seal-brown at ma- 

 turity. 



P. 74, after Paspalum longipedunculatum Le Conte, insert: 

 ua. Paspalum Kentuckiense Nash. Kentucky Paspalum. Culms 

 tufted, 2-5 dm. tall, slender; sheaths ciliate on the overlapping margin, 

 otherwise glabrous; leaves erect, lanceolate, 6 cm. long or less, 4-10 mm. 

 wide, glabrous on both surfaces, ciliate on the margin with hairs less than 

 I mm. long; racemes single or in pairs, 2-5 cm. long; spikelets about 1.6 

 mm. long and about 1.3 mm. wide, glabrous. In dry soil, Ky. and Tenn. 

 June-Aug. The upper surfaces of the leaves in this species are glabrous 

 while in P. longipedunculatum they are pubescent; the marginal leaf-hairs 

 in this are but 1 mm. long, about one-half the length of those in P. longi- 

 pedunculatum. Type collected near Poor Fork P. O., Ky., by T. H. 

 Kearney, Jr., Aug. 1893. 



P. 83, after Panicum amarum, insert: 



10a. Panicum amaroides Scribn. & Merr. Solitary Sea-beach 

 Panicum. A low grass with long rootstocks, from which at rather 

 distant intervals culms arise singly, glaucous foliage, and a slender 

 narrow panicle which bears but few spikelets. Culms 3-8 dm. tall; 

 sheaths overlapping; blades thick and leathery, involute, at least at 

 the apex, 1.5-2.5 dm. long, less than 1 cm. wide; panicle 1-2 dm. long, 

 the branches appressed; spikelets 5-6 mm. long, commonly broad 

 and stout, the first scale much exceeding one-half the length of the 

 spikelet, or often equalling it or nearly so, the second and third scales 

 about equal, all the scales acute. In sands along the coast, Ct. to Fla. 

 and Miss. Aug.-Oct. Differs from P. amarum Ell. by its rootstocks, 

 nearly simple panicle, and larger spikelets. 



P. 84. after Panicum angustifolium, insert: 



21a. Panicum Biishii Nash. Bush's Panicum. A tufted nearly 

 glabrous perennial. Culms about 3 dm. tall, finally much branched; 

 leaves - about 3; blades erect, linear, acuminate, very rough on the margins] 

 ciliate at the base with a few very long hairs, the larger primary 

 blades S-10 em. long, 3—4 mm. \vi( 1 c; panicle much exserted, 6-7 cm. 

 long, its branches ascending; spikelets 2.5 mm. long and about 1.2 mm
