3. F. Caroliniana, Sulliv. & Lesqx. (Muse. Bor.-Amer., No. 253.) 



Capsule, operculum, peristome, and perichjetium nearly as in the last species ; 

 leaves yeUowish-green, dentate on the margin, with a less conspicuous costa ; 

 sporules smaller. — On decayed logs, near the Santee Canal, South Carolina, 

 Ravend. 



4. F. gymnostoma, Sulliv. & Lesqx. (Muse. Bor.-Amer., No. 254.) 

 Leaves whitish-green, elliptical-lanceolate, dentate-cihate ; costa reaching half- 

 way or obsolete ; perichiBtial leaves few, short, obovate, suddenly subulate-acu- 

 minate ; capsule broad-oval, shortly apophysated ; peristome none. — Santa Fe,

71. ANACAMFTODON, Brid. (Tab. IV.) 



Calyptra conic-cuculliform. Operculum conic-subrostellate. Capsule oval, 

 erect, pedicellate. Peristome double; the exterior 16 narrowly lanceolate teeth, 

 smooth on both suifaces, approximated in paii'S, when diy reflexed (hence the 

 name) ; the interior 16 slender cUia, without a basilar membrane. Inflorescence 

 monoecious. — Low, ctespitose, with irregularly branched stems, and spreading 

 ovate-lanceolate semi-costate leaves, of a rather loose and pellucid rhombic areo- 

 lation. (Name from ava/ca/iTrro), to bend back, and 68a)v, a tooth.) 



1. A. splaclmoides, Brid. CUia of the inner peristome always erect j 

 capsule when diy much constricted below the mouth; foliage deep green. — In 

 the forks and open hoUow knots of partly decayed trees : rare, though its range 

 is extensive. (Tab. IV.) (Eu.) 



Tribe XXX. PYLAIS^E^. 



72. PYIiAIS^A, Bryol. Europ. (Tab. IV.) 



Calyptra cuculliform, rostrate. Operculum conic, more or less rosteUate. 

 Capsule oblong, erect, pedicellate. Annulus naiTOW, simple. Peristome double : 

 the exterior 16 linear-lanceolate teeth inserted below the mouth of the capsule; 

 the interior as in Leskea, but with the cUia more or less ruptured along their keel, 

 or a membrane adherent to and bordering the teeth ; cUiolie radimentaiy or 

 none. Inflorescence monoecious : male flower gemmiform, axillary. — Small 

 species, fruiting abundantly, with glossy, concave, elongated, closely Unear- 

 areolated and ecostate leaves ; their alar cellules numerous, small, quadrate, and 

 opaque. (Named for B. de la Pylaie, a Prench botanist.) 



1. P. denticnlata, W. P. Sch. Grows in closely entangled mats ; 

 branches crowded, short, ascending ; leaves lanceolate, acuminate, slightly den- 

 ticulate at the apex ; capsule oblong-cylindrical; pedicels 3" -5" high; opercu- 

 lum with a rostrum about as long as the conic base ; inner peristome firm, yel- 

 low, much as in Leskea, the cilia or processes often split along the keel, the 

 basilar membrane broad ; sporules bright yellow, smooth, about 200 of a line in 

 diameter. — Bark of trees, Columbus, Ohio ; very rare. 



2. P. intricata, Bryol. Europ. Size and mode of growth much as in 

 the last ; branches short, recurved ; leaves ovate-lanceolate, acuminate, nearly
