APPENDIX. 1039 



let 3-4 mm. long, the awn straight, 1.5-2 cm. long. In dry or moist soil, 

 Va.* (according to T. H. Kearney, Jr.) to Fla. and Ala. Sept. and Oct. 

 Differs from A. Virginicus in having the sheaths, at least the lower ones, 

 densely villous all over, and the racemes usually in fours. 



P. 73, after Paspalum laeve Michx., insert: 



5a. Paspalum angustifolium Le Conte. NARROW-LEAVED PASPALUM. 

 Culms tufted, 6-12 dm. tall; sheaths compressed, glabrous; leaves long, 

 the larger 2-4 dm. long, less than i cm. wide, glabrous, or the upper sur- 

 face sometimes sparingly hairy near the base; racemes 3-5, spreading, 

 usually 6-10 cm. long; spikelets singly disposed, 3-3.5 mm. long and about 

 2.5 mm. wide, glabrous. In fields, D. C. to Fla., La., Kans. and Mp. 

 June-Sept. Differs from P. laeve in having the leaves elongated and in 

 the more numerous racemes. 



5b. Paspalum australe Nash, n. sp. 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 

 disposed, oval, 2.7-3 rnm. long and about 2 mm. wide, glabrous. On 

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

 P. Icicle 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. 



After Paspalum circulate 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. laeve 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: 

 i IE. Paspalum Kentuckiense Nash, n. sp. 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 i 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. 82, No. 4, read " Philadelphicum Bernh." instead of "minus (Muhl.) 



Nash ", and refer the latter to synonymy, there being an earlier Panicum 

 pubescens minus Poir. 



P. 83, No. 16, read " linearif olium Scribn." instead of <c Enslini Trin.", 

 and omit synonym at the end.
