Musci. (mosses.) (51) 651 



costa excurrent ; pedicels not arcuate nor so flexuous ; capsule less obovate, 

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

 smooth. — Southern States. 



3, F. Mulilen'berg^i, Schwsegr. Very much smaller than No. 1 or 2 ; 

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

 nate, obtusely serrate, 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. Ft serrata, 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 I'-l^' high, when dry twisted to the left its whole length ; spores 

 larger. — Pennsylvania and southward. 



54. ENTOSTHODOW, Schwagr. (Tab. IV.) 



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

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

 gle : teeth 1 6, short, somewhat fissile, linear-lanceolate, inserted below the orifice 

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

 as in Punaria. — (Name formed of evToaSev, from within, and 68d)V, tooth, 

 alluding to the insertion of the teeth.) 



1. E. Dmmnidndii, SuUiv. Stems l"-2" high; leaves connivent, 

 eUiptic-oblong, rather obtuse, slightly crenate on the margin, concave, costate to 

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

 cels 5" -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 long-subu- 

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

 allied E. Templetoni, Schwcegr. and E. obtusifolius,/.!). Hook. (Tab. IV.) 



55. PHYSCOMITRIUM:, Brid. (Tab. IV.) 



Calyptra long-rostrate, mitriform and lobed at the base, or inflated-cucuUiform. 

 Operculum flattish-convex, with or without an apiculus. Capsule pyriform, 

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

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

 leaves as in Eunaria. (Name from (jivcTKos, something inflated, and fiiTpiov, 

 a little cap.) 



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

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

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

 On the ground ; extremely common. (Eu.)
