MUSCI. (MOSSES.) 6C1 



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. Southern 

 States, Lcsquereux. 



69. MYURELL.A, Bryol. Europ. (Tab. 19.) 



Calyptra cuculliform, narrow. Opercnlum 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 ciliolae, however, very 

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

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

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

 composed of pellucid rhombic cellules. 



1. ]?I. Carey Tina, Sulliv. Stems slender, branched by innovations, 

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

 and ciliate-dentate on the margins ; perichaitia 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 Carolina (Negro Mountain), Gray $ Sullivant. The two othel 

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

 America by Dntmmond. (Tab. 19.) 



TRIBE XXIX. FABRONIEJE. 

 TO. FAB ROM A, Raddi. (Tab. 18.) 



Calyptra cuculliform. 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. Minute species, uniform in habit and size, with prostrate stems, 

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

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

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

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

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



1. F. Wriffhtii, Sulliv. (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 perichaetial leaves. 

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

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

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



2. F. Ravenelii, Sulliv. (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 ; perichsetial 

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

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

 Carolina, Ravend. (Tab. 18.)
