3. F. Carolina ana, Sulliv. & Lesqx. (Muse. Bor.-Amcr., 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 Santee Canal, South Carolina, 

 Ravenel. 



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

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

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

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

 New Mexico, Fendle?: 



71. ANACAIPTODON, Brid. (Tab. 18.) 



Calyptra conic-cuculliform. Operculum eonic-subrostellate. 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 draKauTrra, to bend back, and 68u>v, a tooth.) 



1. A. splaclanoides, 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. PYLAISJEEvE. 



72. PYLAISjEA, Bryol. Europ. (Tab. 18 .) 



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

 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 ; ciliolas rudimentary or 

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

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

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

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



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

 brandies 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 5 o of a line in 

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



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

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