tate border; capsule short, oval, pendulous; operculmn short, conic-acute. 

 White Mountains, New Hampshire, Oakes. 



8. OT. rostra tum, Schwaegr. Stems '-!' high; the sterile branches 

 longer, decumbent or somewhat creeping ; leaves oval-oblong, obtuse, very short- 

 apiculate, the thickened border obtusely dentate ; operculum rostrate, half as long 

 as the capsule; pedicels often 2-5 together. Along woodland rivulets. (Eu.) 



9. HI. cuspidal u ill, Hedw. Stems '-!' high, closely tufted, radicu- 

 lose, the sterile branches arcuate or decumbent ; lower leaves obovate-acuminate, 

 the upper oval-acuminate with a nan-owed base, the thickened border simply ser- 

 rate ; capsule somewhat pendulous, solitary ; operculum convex, scarcely apicu- 

 late. Woods, about the roots of trees : frequent. (Tab. 17.) (Eu.) 



TRIBE XX. MEESIE^E. 



5O. JJIEESIA, Hedw. (Tab. 17.) 



Calyptra small, cuculliform, fugacious. Operculum conic. Capsule apo- 

 physated, erect-cernuous, clavate, with a small oblique mouth, very long-pedi- 

 cellate, narrowly annulate. Peristome double; the exterior of 16 short obtuse 

 teeth, with a medial line ; the interior of 16 carinate cilia, much longer than the 

 teeth, with a narrow basal membrane. Inflorescence various : male flower with 

 clavate paraphyses. Tall and striking species, inhabiting bogs and swamps, 

 remarkable for their slender stems and long pedicels, in habit Bryoid, in shape 

 of capsule allied to the Funarieae ; leaves of a lanceolate outline, with a semi- 

 amplexicaul and decurrent base ; the costa percurrent ; areolse small, compact, 

 oblong. (Named for D. Meese, a Dutch botanist.) 



1. JXE. longiseta, Hedw. Hermaphrodite; stems 3' -5' high, tomentose ; 

 leaves ovate-lanceolate, spreading, plane and entire on the margins, serrate, twist- 

 ed when dry ; capsule clavate-pyriform, incurved, the apophysis constituting half 

 its length (as iii the other species) ; the exterior peristome more or less adherent 

 to the interior; annulus rather persistent; operculum obtuse; pedicels 4' -5' 

 long. Cranberry marshes, Northern Ohio. A variety, smaller in all its parts, 

 occurs among the mountains of New England. (Tab. 17.) (Eu.) 



2. ME. tristicha, Br & Sch. Distinguished from the preceding by its 

 3-ranked, wider, squarrose and denticulate leaves, and the dioecious inflorescence, 

 with a terminal discoid male flower. Grows in similar places. (Eu.) 



3. M. llligindsa, Hedw. Smaller than No. 1 and 2, monoecious and 

 hermaphrodite on the same plant ; leaves linear-lanceolate or linear, obtuse, 

 with entire recurved margins and a heavy costa; operculum truncate. White
