Musci. (mosses.) (61) 661 



broad reddish rim ; teeth of the peristome not nodose ; inner peristome better 

 developed, the short carinate cilia quite evident ; perichsetial leaves yellowish. 

 — Dry, sandy and hilly ground, in thin woods, never on trees. — Soathem 

 States, Lesquereux. 



69. MYUREttA, Bryol. Europ. (Tab. V.) 



Calyptra cucuUiform, narrow. Operculum convex-conic, obtuse, large. Cap- 

 sule oval or obovate-oval, with a short and tumid erect collum, pedicellate, an- 

 nulate. Peristome large, constructed as in Hypnum ; the cUiolffi, however, very 

 short, often absent. Inflorescence dioecious. — Small, subalpine, glaucous green, 

 densely tufted species ; with erect, sparingly divided, julaceous, stoloniferous 

 stems ; and closely imbricating, subrotund, ecostate, more or less papillose leaves, 

 composed of pellucid rhombic ceUules. 



1. M. Carey ana, SuUiv. Stems slender, branched by innovations j 

 leaves very concave, with a short filiform point, strongly papillose on the back, 

 and ciliate-dentate on the margins ; perichsetia orange-red, leaves smooth, nar- 

 rowly lanceolate, filiformly acuminate, the margins at the upper end of the lami- 

 na fringed. — High mountain-tops. New England, J. Carey : Pennsylvania, Les- 

 quereux: North Cai-olina (Negro Mountain), Gray §- Sullivant. — The two other 

 species of this genus, M. julacea ^nd M. apiculata, were collected in British 

 Amsncahj Drummond. (Tab. V.) 



Tribe XXIX. FABKONIE^. 

 TO. FABROJVIA, Eaddi. (Tab. IV.) 



Calyptra cucuUiform. Operculum conic, acuminate. Capsule pyriform, erect, 

 pedicellate ; its mouth wide. Peristome single (in No. 4 absent) ; the exterior 16 

 linear-lanceolate teeth approximated in pairs, when dry reflexed. Inflorescence 

 monoecious. — Slinute species, uniform in habit and size, with prostrate stems, 

 and erect crowded subfasciculate branches; leaves shining, ovate-lanceolate, 

 filiformly acuminate, dentate or ciliate, semi-costate ; the areolation lax, pellu- 

 cid, the cellules at the basal angles quadrate, elsewhere larger and rhomboidal, 

 with conspicuous primordial utricles : reticulation of the capsule-waU quadrate, 

 flexuous. (Named after Fabroni, an Italian botanist.) 



1. F. Tfriglitii, SuUiv. (Muse. Bor.-Amer., No. 251.) Capsule oblong- 

 pyriform ; operculum conic-rostellate ; teeth of the peristome light golden-yel- 

 low ; the vaginula concealed by the gradually acuminated perichsetial leaves. — 

 San Marcos, Texas, Wright. — Near the European E. octoblepharis ; but that 

 species has a mameUate operculum, dark brownish-red peristomial teeth, leaves 

 with more numerous quadrate alar ceUules, and an emergent vaginula. 



2. F. Bavenelii, SuUiv. (Muse. Bor.-Amer., No. 252.) Leaves of a 

 clear deep-green color, closely imbricating, entire on the margins, or occasionally 

 with a few teeth ; costa distinct, extending beyond the middle ; perichaitial 

 leaves numerous, dentate, graduaUy acuminate ; vaginula as in No. 1 ; teeth of 

 the peristome rather short, dusky yeUow ; sporules large. — On dry rocks. South 

 CaroHna, Ravenel. (Tab. IV.)
