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

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

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

 sporulcs smaller. On decayed logs, near the Santce Canal, South Carolina, 

 Ravenel. 



4 F. gyuillOStoma, Sulliv. & Lesqx. (Muse. Bor.-Amcr., No. 254.) 

 Leaves whitish-green, elliptical-lanceolate, dcntate-ciliate ; costa reaching half- 

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

 minate ; capsule broad-oval, shortly apophysated ; peristome none. Santa F6, 

 New Mexico, Fendler. 



71. ANACAU1PTODON, Brid. (Tab. is.) 



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

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

 smooth on both surfaces, approximated in pairs, when dry reflexed (hence the 

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

 monoecious. Low, caespitose, with irregularly branched stems, and spreading 

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

 lation. (Name from aixiKa/iTrrco, to bend back, and o8o>v, a tooth.) 



1. A. SplaclliiOldcs, Brid. Cilia of the inner peristome always erect ; 

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

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

 is extensive. (Tab. 18.) (Eu.) 



TRIBE XXX. PYLAISJEfc^E. 



72. PYLAIS^EA, Bryol. Europ. (Tab. 18.) 



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

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

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

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

 or a membrane adherent to and bordering the teeth ; ciliolac rudimentary or 

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

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

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

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



1. P. deilticulftta, 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 00 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
