580. L-EJEUITIA, Lib. 



[Dedicated to A. L. S. Lcjeune,& French Botanist.] 



fructification lateral, or terminal, on proper branches. Involucral 

 leaves 2, deeply 2-lobed. Perianth oval or obovoid, terete or angular, 

 winged or ciliate-crested on the angles, the mouth 3- or 4-lobed. 

 Pistillidium single. Calyptra obovoid, persistent, with a style, 

 rupturing below the apex. Pedicel short, jointed in rings, when 

 dry zigzag. Capsule globose, membranaceous, pale, 4-cleft to the 

 middle, the valves connivent. Maters persistent, adherent to the 

 tips of the valves, erect, the upper end truncate-dilated, with a 

 single spiral fibre. Spores large, irregular. Dioicous. Antheridia 

 on proper branches lodged in the ventricose base of imbricated 2- 

 lobed perigonial leaves. Foliaceous : stem-leaves bifarious, incubous. 



1. I. crl.vpciltil, Schwein. [Bucklered] : Stems procumbent, 

 somewhat pinnately branched; leaves very pale green, with the 

 upper lobe round-obovate and deflexed, the lower oblong, quadrate; 

 amphigastria orbicular, approximated; perianth lateral, sessile, 

 obovoid, obtusely keeled on the back, 2-keeled beneath, the margin 

 rather compressed. On old trees, &c. 



TRIBE 6. FRONDO^SAE. 

 581. PEM7IA, Radd, 



[A personal name.] 



Fructification proceeding from the back of the frond, near the apex. 

 Involucre cup-shaped, short, the margin lacerate. Perianth none. 

 Calyptra oval, membranaceous, longer or shorter than the involucre. 

 Capsule globose, pedicellate, 4-valved. Elaters long, free, with 2 

 fibres. Monoicous. Antheridia globose, immersed in the upper 

 surface of the broad indeterminate midrib of the frond. 



1. P. epipliyl'la, Nees. [Epiphyllous] : Frond dark olive- 

 green, rather membranaceous, sparingly divided ; divisions oblong, 

 somewhat cuneate, repand-lobed $ calyptra exserted, smooth. 

 Moist shady places, on the ground, forming large patches. 



582. AtfEU'RA, Dumortier. 

 [Gr. a, privative, and Neuron, a nerve; the frond being nerveless.] 



Fructification arising from the under side near the margin of the 

 frond. Involucre cup-shaped, very short and lacerate, or none. 

 Perianth none. Calyplra ascending, nearly cylindrical, fleshy. 

 Capsule pedicellate, oval or oblong. Elaters adherent to the apex 

 of the valves, containing a single broad spiral fibre. Inflorescence 

 mouoicous. Antheridia immersed in the upper surface of receptacles 

 proceeding from the margin of the frond, which is fleshy and des- 

 titute of a midrib. 



1. A. S6silis, Sprengel. [Sessile] : Fronds 1 to 2 inches long, 

 and 3 to 5 lines wide, irregularly lobed ; involucre none ; calyptra 

 papillose at apex ; pedicel 9 to 12 lines high ; sterile receptacles 

 elongated and tapering deflexed processes. Rotten logs. 



Obs. Specimens have been found (though, as yet, only in a sterile 

 state,) which agree well with the description of A. multifida, 

 Dumort,
