top ; areolation uniform, hexagonal ; cup of 3-4 obcordate, obsoletely 

 nerved bracts, enclosing many flattened lenticular, stalked gemmse, 

 intermixed with paraphyses, these gemmas are altered antheridia, as 

 the cups often arise in pairs just as the perfect males do. 

 Occasionally also a gemmiferous shoot may be found growing from 

 a female inflorescence. 

 Hab. — Damp, shady rocks, rotten stumps of trees, decayed palings, and 



on turfy banks on heaths, not uncommon. Fr. 7-9. Plentiful about 



Killarney, but otherwise rather scarce in Ireland, as it also is in 



Cornwall. 



This beautiful moss is widely distributed, and in North America 

 besides the ordinary form, a variety {curvata Lindb.) is common, having a 

 narrower, curved capsule. The leaves vary much in size, as well as in 

 density of arrangement, and we have seen stems of the gemmiferous 

 plant, having them almost circular. It is also not uncommon to find 

 gemmae, which have dropped from the cups, entangled among the leaves 

 and attached to the stem by radicles they have thrown out. The second 

 species — G. geniculata Girgens. — is a native of Japan and N. West 

 America, and differs from the European species chiefly in the seta, 

 which is suddenly bent about the middle to an obtuse angle, and roughly 

 tuberculate above the bend. 



Sect. 2. TETRODONTIUM. Schw^g. 



Plants very small, gregarious, simple, having the long frondiform 

 leaves, permanent or vanishing, or sometimes with lateral flagelliform 

 ramuli, bearing very minute imbricated leaves ; capsule oval. 



2. GEORGIA BROWNII. (Dicks.) C. Muell. 



Autoicous ; plants dwarf, gregarious, the stem with or without 

 flagelliform ramuli, the perichsetial bracts ovate, acuminate, nerved 

 half-way ; capsule oval ; lid conic, oblique. (T. IV. B.)
