﻿Nash : New or noteworthy American Grasses 85 



Along the coast, Maine to New York. I take pleasure in nam- 

 ing this grass for Mr. Alvah A. Eaton, who sent me specimens 

 of it collected by himself at Seabrook, N. H. 



Panicum polyanthes Schultes, Mant. 2: 257. 1824. 



Panicum multiflorum Ell. Bot. S. C. & Ga. 1 : 122. 1817. Not 

 Poir. 1 8 16. 



Panicum microcarpon Muhl. Descr. Gram. in. June, 1817. Not 



€x Elliott. Jan. 1817, 



Another long familiar name must give place to one of Schultes. 

 Elliott's conception of the P. microcarpon of Muhlenberg, as indi- 

 cated by his description and a specimen from him in the herbarium 

 of Columbia University, was, unfortunately, at variance with that 

 of Muhlenberg himself, so that Elliott's publication of the name, 

 accredited by him to Muhlenberg, invalidated the latter's publi- 

 cation of the same name, rightly applied, some five months later. 

 The P. multiflorum of Elliott, on account of Poiret's earlier publi- 

 cation, becomes a homonym. That of Schultes, founded on P. 

 multiflorum Ell., is apparently the next available. 



Panicum pseudanceps sp. nov. 



Whole plant, with the exceptions noted below, smooth and 

 glabrous. Culms caespitose, 3-7 dm. tall, erect, slender, much 

 compressed, at length branching at each node ; nodes 2 or 3 ; 

 sheaths compressed and keeled, shorter than the elongated inter- 

 nodes, an external tuft of long hairs on each side at the apex; 

 ligule a ring of hairs 2-3 mm. long ; leaves narrowly linear, elon- 

 gated, conduplicate, at least when dry, 1-3 dm. long, 2-4 mm. 

 wide, long-acuminate at the apex, a little narrowed toward the 

 base, somewhat pilose on the upper surface at and near the base, 

 the basal leaves numerous, about one-half as long as the culm, the 

 culm leaves 2 or 3; panicle long-exserted, narrow, 1-2 dm. long, 

 its branches hispidulous, in i's-3's, slender, erect, somewhat flex- 

 uous, the larger 5-9 cm. long ; spikelets numerous, 2.5 mm. long, 

 lanceolate when closed, often with 1-3 bristles at the base, on his- 

 pidulous pedicels commonly shorter than themselves, appressed, 

 the first, second and third scales membranous, acute, the first and 

 second a little hispidulous on the keel toward the apex, the first 

 scale about two-fifths as long as the spikelet, broadly triangular- 

 ovate, 3-nerved, the second and third scales equal in length, 

 broadly-ovate when spread out, the second 5-7-nerved, the third 

 5-nerved and enclosing a 2-nerved hyaline palet somewhat shorter
