MTJSCI. (mosses.) 651 



costa excuirent ; pedicels not arcnate nor so flcxuons ; capsule less obovate, 

 very slightly furrowed when dry ; mouth larger, not so oblique, and its border 

 smooth. — Southern States. 



3. F. Mllhlcnbergii, Schwsegr. Very much smaller than No. 1 or 2; 

 stems l"-3" high ; upper leaves erect-patent, oblong-obovate, suddenly acumi- 

 nate, obtusely sen-ate, the costa ceasing below the point ; capsule shortly pyri- 

 form, not furrowed when dry; operculum convex, apiculate; annulus none; 

 pedicels 6" -8" high, twisted to the right when dry; spores more than twice the 

 diameter of those of No. 1, granular on the surface. — Pennsylvania. (Eu.) 



4. P. SCi'J'ista, Beauv. Intermediate in size between Nos. 1 and 3; com- 

 pared with the last, the leaves are longer, spatulate-lanceolate, distantly and 

 sharply serrated above, the costa excurrent ; operculum convex, not apiculate ; 

 the pedicel l'-H'high, when dry twisted to the left its whole length ; spores 

 larger. — Pennsylvania and southward. 



54. ENTOSTHODON, Schwaegr. (Tab. 18.) 



Calyptra rostrate, cuculliform, inflated below. Operculum depressed-convex. 

 Capsule erect, pyrifonn, symmetrical, smooth, long-pedicellate. Peristome sin- 

 gle : teeth 16, short, somewhat fissile, linear-lanceolate, inserted below the orifice 

 of the capsule, horizontal. — Inflorescence, ramification, and structure of leavc3 

 as in Funaria. — (Name formed of zvt<xt6cv, from within, and oSeov, tooth, 

 alluding to the insertion of the teeth.) 



1. E. DraiumdBUlii, Sulliv. Stems I"- 2" high; leaves connivent, 

 elliptic-oblong, rather obtuse, slightly erenate on the margin, concave, costate to 

 the apex, areolation large ; capsule globose-pyriform, operculum flatfish ; pedi- 

 cels o"-7" high ; calyptra erect, with a straight subulate rostrum as long as the 

 capsule.— (E. obtusifolius, Hook, §■ Wils. in Drum. 2d coll. No. 36.) — Wet, 

 clayey soil, Southern States. — The short-pyriform capsule and the Iong-subu- 

 Iate rostrum of the calyptra, readily distinguish this species from the nearly 

 allied E. Templetoni, Schwaegr. and E. obtusifolius, J. D. Hook. (Tab. 18.) 



55. piiirscoiriiTRiinn, Brid. (Tab. is.) 



Calyptra long-rostrate, mitrifonn and Iobed at the base, or inflated-cuculliform. 

 Operculum flatfish-convex, with or without an apiculus. Capsule pyrifonn, 

 symmetrical, exannulate, its pedicel mostly erect. Peristome wanting. — An- 

 nual and biennial plants, with the inflorescence, ramification, and structure of 

 leaves as in Funaria. (Name from (pvaicos, something inflated, and pirpiov, 

 a little cap.) 



1. P. pyriformo, Br. & Sch. Stems 2" -5" high; leaves spatulate- 

 lanceolate, serrate, spreading, the costa nearly perenrrent, capsule globose-pyri- 

 form, on an erect exserted pedicel 5" -8" long; calyptra mitriform, lobed. — 

 On the ground ; extremely common. (Eu.) 



2. P. immei'SHm, Sulliv. Leaves oliovate-lanceolate, sen-ate, the costa
