650 (50) Musci. (mosses.) 



7. B« radicalis, Beauv. Monoecious; stems short ; leaves linear-lanceo- 

 late, erect, cuspidate by the long-excurrent scabrous costa ; male flower gemmi- 

 form, close to the female. — "Wet clay-banks, Ohio and southward. 



52. CONOSTOMUM, Swartz. (Tab. IH.) 



Calyptra cuculliform. Operculum conic-rostellate. Capsule globular, cer- 

 nuous, exannulate, with a long erect pedicel. Peristome single : teeth 16, linear- 

 lanceolate, prominently articulated, with a medial line, united at their apices. 

 Inflorescence dioecious: male flower subdiscoid, with clavate paraphyses. — A 

 genus scarcely distinguishable from Bartramia, difi"ering only in the stnictm'e of 

 the peristome, the rostellate operculiun, and the larger and less fugacious calyp- 

 tra. (Name from kSivos, a cone, and (XTOfia, a mouth, in allusion to the cone-like 

 appearance of the peristome.) 



1. C. borealC) Swartz. Stems compactly casspitose, ^'-2' high, glau- 

 cous-green above, brownish below ; leaves erect, imbricated in 5 rows, lanceo- 

 late-acuminate, serrate, shai-ply carinate, mucronate by the excurrent costa. — 

 On rocks, in bleak alpine situations. White Mountains of New Hampshire.

Tkibe XXn. FUNAEIE^. 



53. FUJVABIA, Schreb. (Tab. IH.) 



Calyptra cuculliform, inflated below, subulate above. Operculum conic or 

 convex-obtuse. Capsule obliquely pyriform, rather ventiicose, cernuous, with a 

 small oblique mouth, long-pedicellate. Peristome double : the exterior of 16 

 teeth, oblique, lanceolate-attenuated, and connected at their apices by a small 

 reticulated disk; the interior a membrane divided to the base into 16 lanceolate 

 cilia, opposite the teeth. Inflorescence monoecious : male flower subdiscoid, 

 its paraphyses much enlarged at their apex. — Annual or biennial gregarious 

 plants, growing on the ground ; stems at first simple, terminated by a male 

 flower, afterwards branched, the branches producing fertile flowers ; lower leaves 

 remote ; upper ones clustered, larger, broad-lanceolate, of a thin and loose tex- 

 ture ; the areolae large, hexagonal-oblong ; costa loosely cellular, ceasing below 

 the apex. (Name from funis, a rope, from the twisted pedicel.) 



1. F. bygTOmctrica, Hedw. Stems 3"- 10" high; upper and peri- 

 chsetial leaves connivent, crowded into a bud-like cluster, broadly ovate-lanceo- 

 late, very concave, entire, costate nearly to the apex ; the perigonial leaves 

 serrate ; capsule furrowed when dry, the border of its mouth coiTugated ; annu- 

 lus large, spirally unrolling ; pedicel (2' -3' long) arcuate and flexuous. — Var. 

 CALVESCENS has the pedicel more elongated and straight, the capsule more 

 slender, and almost erect. — Very common, on the ground (particularly when 

 lately burnt over), and on walls ; the vaiiety occui-s mostly in the Southern 

 States. (Tab. m.) (Eu.) 



2. F. fldvicans, Michx. In general appearance very much like the last ; 

 but the color paler ; leaves not so connivent and with a long cuspidate point, the
