2. Fedia UMBiLicATA (sp. uov.)'. friictu snbgloboso-inflato gla- 

 bro apice unidentato antice profunde urabilicato, loculis sterilibus 

 fertili multoties majoribus, bracteis subspatulato-linearibus eciliatis. 



Hab. Around Columbus, Ohio. 



Obs. This species has the appearance of F. radiata, and F. 

 Fagopyrum, Torr. ^' Gray (which also occurs in the central 

 part of Ohio,) but is more nearly allied to F. pumila, of the 

 south of Europe. The inflated sterile cells are in contact from 

 top to bottom, and have a common dissepiment, (which, how- 

 ever, is often wanting or incomplete in the full-grown fruit,) but 

 there is a deep circular depression in the middle of the anterior 

 face. The flattened fertile cell is one-nerved on the back, under 

 a lens ; and is produced at the apex into a blunt, somewhat con- 

 spicuous tooth. 



3. Eleocharis compeessa {sp. nov.) : culmis casspitosis valde 

 compressis (in siccis spiraliter tortis), spica oblongo-ovata acuta, 

 squamis ovato-lanceolatis acutis ad apicem Soepissime bifidis, 

 staminibus 3, stylo trifido, achenio obovato-pyriformi trigono 

 punctatulo nitido apice in breve collum basi styli abbreviato-con- 

 ica coronatuni constricto, setis nnllis. 



Hab. Wet places in the Darby Plains, fifteen miles west of 

 Columbus, Ohio. 



Descr. Culm csespitose, 12-18 inches high, slender, much 

 compressed, strongly striate, closely invested at the base with a 

 single, horizontally truncate sheath. Spike 3-5 lines in length, 

 oblong-ovate, terete, acute, many-flowered. Scales ovate-lan- 

 ceolate, acute, of a rather firm texture, dark purple on the back, 

 with a broad white transparent margin, entire, except the apex, 

 which (even in the young state) is deeply 2-cleft, the segments 

 contorted. Bristles none. Achenium obovate, pyriform, obtusely 

 triangular, of a light golden color, shining, minutely pitted lon- 

 gitudinally ; the raised margins of the pits traversing it in undu- 

 lating lines. Tubercle fuscous, small, not one-sixth the length 

 of the achenium, which is contracted into a short neck be- 

 neath it.
