 from the base ; leaves elongated-oblong, minutely denticulate on the subpella- 

 cid margin, obtuse ; costa shortly excurrent ; capsule oblong or obovate, inclined

 monoecious ; male flower gemmiform at the base of the fertile stem. Woods,

10. F. adiantotdes, Hcdw. Stems much branched, 1'- 3' long; leaves 

 oblong-lanceolate, serrulate, 2 or 3 rows of the marginal cellules transparent ; 

 costa percurrent ; capsule oval-oblong, inclined ; pedicel from the middle of the 

 stem ; operculum and calyptra as in No. 8 ; inflorescence as in No. 5. Shaded

11. F. polypodioides, Hedw. Stems broad, 1'- 2' high; leaves ovate- 

 or elongated-oblong ; costa vanishing at the subdenticulate obtuse apex ; capsule 

 obovate-oblong ; operculum subulate-rostrate from a large rather hemispherical 

 base ; pedicel short, flexuous, arising from the upper part of the stem ; calyptra

Calyptra small, campanulate-niitriform, lobed at the base. Operculum 

 bemi spherical, apiculate. Capsule immersed spherical, nearly sessile, exan- 

 nulate. Peristome none. Inflorescence monccious or hermaphrodite : para- 

 physes globosely distended at the apex. A genus, by its feeble dehiscence, 

 globose capsule, and the characters of vegetation, forming an intermediate 

 link between Phy scorn itrella among Cleistocarpous, and Physeomitrium 

 among Stegocarpous Mosses. (Name from dfyavijc, unapparent, and /foyj/ta, 

 rupture, or suture ; L e. dehiscence obscure.)
