fault, for there is a specimen in the Torrey Herbarium dating back 

 to 1864. Mr. Smith has sent me the following note on the 

 locality : " It is in a small patch of Sphagnum in a field, 300 feet 

 above tide-water." Mr. Martindale has it from the ballast 

 grounds at Camden, but there seems no doubt that the Delaware 

 County plant is a native. It is not quite as stout as the plants 

 from Asia and Mauritius, but agrees very well with French speci- 

 mens in Herb. Torrey. 



Scirpus stenopJiy litis, Ell. {Isolepis stenophylla, Torr.), appears 

 to be a true Scirpus, and is nearly related to S. barbatus, Rottb., 

 to which it has been referred by Boeckeler, Linnaea, xxxvi., p. 

 792, as var. Americanus. It seems to me specifically distinct, 

 but if reducible to a variety of Rottboll's species, a result by no 

 means impossible when more material is obtained, it must bear 

 Elliott's name. 



Hemicarpha micrantha (Vahl.) {Scirpus micranthus, 

 Vahl, Enum. PI., ii., 254 (1806) ; H. subsguarrosa, Nees, in Mart. 

 Flor. Bras., ii., Pars, i., p. 61 (1842.) 



Rhynchospora axillaris (Lam.) {Schcenus axillaris, 

 Lam., Encyc, i., 137 (1791); R. cephalantha. Gray, Ann. Lye, 

 N. Y., iii., 218 (1836.) 



In taking up the name I am guided by Boeckeler in Linnaea, 

 xxxvii., p. 572, who states that he saw a specimen named by 

 Lamarck in Willdenow's Herbarium. 



SCLERIA GRAMINIFOLIA, n. sp. Culms 35 to 40 cm. high, 

 slender, erect, triangular in section; leaves 3 or 4, 12-15 cm. 

 long, all cauline, narrowly linear, attenuate to an acute apex, the 

 upper reaching to the inflorescence but not overtopping it ; pani- 

 cle terminal, loose and quite simple, 4 to 5 cm. long, subtended 

 by a linear bract, 2 to 6 cm. long ; heads androgynous, sessile, 

 or on peduncles i to 2 cm. long, of from 2 to 5 flowers, the fer- 

 tile and sterile about equal in number. Achenium globular, 2 

 mm. in diameter, obtuse, minute apiculate, roughened, with 

 short projecting processes, supported on a triangular perigynium, 

 whose angles are prolonged upwards as ridges nearly to the apex 

 of the achenium. Rootstocks fibrous. 



Collected by C. G. Pringle in wet places, pine barrens, base of 

 the Sierra Madre, Chihuahua, Sept. 28, 1887 (No. 1401.)
