702 (102) HEPATIC^, (liverworts.) 



leaves usually 3-toothed at the apex. Stems flagelliferous (whence the name, 

 from fiaari^i a whip or lash, and ^pvov, Moss). 



1. M. trilobatum, Nees. Leaves ovate, antrorsely gibbous at the dor- 

 sal base, broad and acutely 3-toothed at the apex ; amphigastria 4 - 6-toothed, 

 the teeth denticulate. — On the damp ground, Alleghany Mountains and north- 

 ward. Stems 3' -5' long; the foliage firm, varying from olive-green to brown- 

 ish-yellow. (Tab. VIII.) (Eu.) 



2. HI. tridenticulatum, Lindenb. Scarcely distinct from the pre- 

 ceding : described as having oblong, obtuse, shorter, less oblique, and less con- 

 cave leaves, with minute and often obsolete teeth : its habitat (swamps of the 

 Southern States) is different. 



3. M. deflcxuni; Nces. Leaves ovate or ovate-oblong, the dorsal mar- 

 gin arched, the narrow apex 2 - 3-toothed or entire ; amphigastria 2-cleft, crenate 

 or entire. — Rocky places. — Variable ; much smaller than the last, fragile, of a 

 dark brownish hue. — M. denudatum and M. ambiguum, G. L. Sf N. Synop. 

 Hepat., are probably forms of this species. (Eu.) 



37. L-EPIDOZIA, Nees. Creeping Scale-Moss. (Tab. VIIL) 



Fructification terminal, on short proper branches arising from the under side 

 of the stem. Involucral leaves numerous, small, broad, 2 - 4-toothed at the 

 apex. Perianth elongated, obtusely 3-plaited, the mouth denticulate. Calyptra 

 membranaceous. Capsule globose. Elaters with two spiral fibres. Antheridia 

 on short spike-like branches, arising from the under side of the stem, singly 

 lodged in the base of conduphcate 2-3-cleft perigonial leaves. Stem-leaves 

 4-toothed or 4-parted. Amphigastria present. (Name from XeTriSJco, to cover 

 with scales ; in allusion to the scale-like foliage.) 



1. L<. reptauS; Nees. Stems creeping, pinnately compound or decom- 

 pound; leaves decurved, quadrate, acutely 3 -4-toothed; amphigastria 3-4- 

 cleft. — Hilly districts, on the ground. (Tab. VIII.) (Eu.)

 by one side of its mouth to the stem, pendent. Calyptra membranaceous, partly 

 connate with the involucre. Capsule oblong, twisted ; the valves narrow and 

 contorted. Elaters with two spiral fibres. Antheridia on short lateral capitate 

 branches, one in each of the scale-like perigonial leaves. Stem-leaves entire or 

 2-toothed. Amphigastria 2-cleft. (Name compounded of koKv^, flower-cup, 

 ino, under, and yala, the ground; from the position of the fructification.) 



1. C Trichoiuanis, Corda. Leaves roundish-ovate, obtuse, spread- 

 ing, imbricated; perianths imbedded in the soil. — Moist or springy places, on 

 the ground, — Foliage delicate, pale glaucous-green. (Tab. VIII.) (Eu.)
