On rocky sides of shaded rivers, also in wet spots of the mountains, 

 reaching fifteen hundred feet above the level of the sea. Flowers at 

 Dunkerron, County of Kerry, during spring, summer, and autumn. 

 Frond from one to three inches long, oblong, sinuate, at the top bilobed, 

 (as in all this natural order) ; the margins crenate, depressed, often 

 purplish and scariose ; the openings of the pores thickened or mar- 

 ginate. The scales beneath (observable in young fronds) dark purple, 

 oblong, scymitar shaped, imbricated about the buds. The indusium 

 rotundate, depressed, its scales multifid, and their lacinice linear, articu- 

 late, purplish. Female Receptacle pedunculate, often with four indis- 

 tinct angles, above having four obtuse ribs. Loculi usually four, yet 

 one or two often abortive and collapsed ; of the fertile the margins are 

 at first much plicate, and even after expansion undulate. Calyces 

 often two or three, reticulated, rotund, toothed. Calyptra rotundate, 

 Bearing a style. Capsule globose, shortly pedicellated. Seeds sub- 

 muricate, rotundato-tetrahedrous, dark brown : the filaments with a 

 double spiral line. The peduncle one to two inches high, reddish 

 below, pale green above, with two grooves containing bundles of fibres 

 as in the preceding. Specimens are not very uncommon in which the 

 peduncle is truly androgynous, i. e. a part of the receptacle bearing 

 capsules below, the rest bearing anthers on its superior surface. The 

 male receptacle is pedunculated, its margin elevated, entire, scariose. 

 The loculi of the anthers are disposed in a radiating manner. The 

 anthers are oblong. This plant, well described by Schmidel and 

 Wahlenberg under another name, seems to have been unknown to 

 Micheli, Dillenius, and Haller. 



2. FEGATELLA. Ccesafpinus. Raddi. 



Male Receptacle sessile in a pit of the frond ; Female Receptacle 

 covering the loculi; Loculi 4 5, opening with a vertical fis- 

 sure ; Calyces none ; Calyptra at length bursting and remain- 

 ing in the loculus. 



It may be doubted whether by Fegatella Caesalpinus understood 

 this species or Marchantia polymorpha. Scyphi containing gemmce 

 or buds never occur in this genus. While the Marchantice flower 

 throughout the spring, summer, and autumn, the FegatelicB exhibit 

 their organs of fructification only early in the spring, and then for a 

 short period in Ireland. The pores of the fronds never have their 

 openings thickened or marginate as in Marchantia; and the peduncles 

 have but a single groove, never two, as in the latter. 



1. F. conica, Female Receptacle conical, narrowed and ob- 

 tuse at the top ; the capsules at length exserted. Marchantia
