710 JUNGERMANNIACE^E. (SCALE-MOSSES.) 



lobed. Calyptra small, obovate, deeply trifid. Capsule large, globose. Elaters 

 free. Spores large, muriculate. Antheridia iu the bases of leaves of a short 

 terminal spike. (Named for William Herbert, an English botanist.) 



1 . H. adlinca, S. F. Gray. Stems long and slender, erect, brownish, nearly 

 simple ; leaves and underleaves almost alike, curved and one-sided, the lobes 

 lanceolate. (Sendtnera juuiperiua, Sulliv.; not Nees.) On rocks, Green- 

 wood Mts., N. J., Catskill Mts., N. Y., and probably northward. (Eu.) 



9. BAZZANIA, S. F. Gray. (PI. 24.) 



Leaves incubous, oblique, decurved, mostly truucate-tridentate ;- underleaves 

 wider than the stem, mostly 3-4-toothed or crenate. Dioecious. Fruit on a 

 short branch from the axil of an underleaf. Involucral leaves much imbri- 

 cate, concave, orbicular or ovate, incised at the apex ; perianth ovate-subulate 

 or fusiform, somewhat 3-keeled. Calyptra pyriform or cyliudric-oblong. Cap- 

 sule oblong. Antheridial spikes from the axils of underleaves. (Named for 

 M. Bazzani, an Italian Professor of Anatomy.) 



1. B. trilobata, S. F. Gray. (PL 24.) Creeping, dichotomous, prolifer- 

 ous; leaves ovate, the broad apex acutely 3-toothed ; underleaves roundish- 

 quadrangular, spreading, 4 - 6-toothed above ; perianth curved, cylindric, pli- 

 cate at the narrow apex and 3-toothed. (Mastigobryum trilobatum, Nees. 

 M. tridenticulatum, Lindenb.) Ravines, wet woods and swamps; common 

 and variable. (Eu.) 



2. B. deflexa, Underw. Stems forked or alternately branched ; leaves 

 stronglv deflexed, cordate-ovate or ovate-oblong, falcate, the upper margin 

 arcuate, the narrow apex 2 - 3-toothed or entire ; underleaves roundish-quad- 

 rate, the upper margin bifid, crenate, or entire; perianth cylindric, arcuate, 

 plicate above and denticulate. (Mastigobryum deflexum, Nees.) On rocks 

 in the higher mountains eastward. (Eu.) 



10. LEPIDOZIA, Dumort. (PL 24.) 



Leaves small, incubous, palmately 2-4-cleft or -parted; underleaves simi- 

 lar, often smaller. Dioecious or rarely monoecious. Fruit terminal on short 

 branches from the under side of the stem. Involucral leaves small, appressed, 

 concave, 2 - 4-cleft ; perianth elongated, ovate-subulate or narrowly fusiform, 

 obtusely triangular above, entire or denticulate. Calyptra included, pyriform 

 or oblong. Capsule oblong-cylindric. Spores minute, smooth or roughish. 

 Antheridia large, pedicelled, solitary in the axils of 2-cleft spicate leaves. 

 (Name from \eiris, a scale, and 6os, a shoot, for the scale-like foliage.) 



1. L. reptans, Dumort. (PL 24.) Creeping, pinnately compound, the 

 branches often flagellate; leaves decurved, subquad rate, 3 -4-cleft ; involucral 

 leaves ovate, truncate, unequally 4-toothed ; perianth incurved, dentate. On 

 the ground and rctten wood, N. J., and common northward. (Eu.) 



2. L. setacea, Mitt. Leaves deeply 2 -3-cleft or -parted, incurved, the 

 lobes subulate, formed of a somewhat double series of cells ; underleaves sim- 

 ilar; perianth ciliate. (Juugermannia setacea, Web.) On the ground and 

 rotten wood ; common. Resembling the next in its leaves, but smaller and 

 browrish. (Eu.)
