 Bogs, upon the ground and on the dung of animals, frequent in the 

 south, where it is almost the only species : rare in the north, especially 

 in Scotland. Pentland hills, Mr. Maughan. Isle of Arran, Dr. Bain- 

 bridge. Near Ayr, Mr. James Wilson. Hill near Helensburgh, Mr. 

 Hopkirk and Joseph Dalton Hooker. Forest of Glenmore, Arnott and 

 Hook.; but always in small quantity. Fr. Summer. — Fine specimens of 

 this plant, with the perfectly flagon-shaped capsules and long, graceful, 

 delicately-coloured setce, are equalled by few mosses in beauty, and sur- 

 passed perhaps by none, save the infinitely rarer Splachna, rubrum and 

 luteum, of the North of Europe and America. 



** Leaves obtuse, or rarely acute. 



6. S. vasculosum, Hedw. {large-fruited Splachnum); leaves 

 rhombeo-rotundate, the nerve disappearing below the point, 



apophysis globose much wider than the capsule a. leaves 



obtuse. S. vasculosum, Hedw. St. Cr. v. 2. p. 15. Grev. Fl.

Scottish mountains, at the sources of springs, principally among the 

 Breadalbane mountains, bearing fruit on Ben More in the greatest pro- 

 fusion. Clova. Mr. Drummond. Catlaw near Kinnordy. Arnolt and 

 Hook. Fr. Summer. — The leaves are almost equal in size to those of 

 Bryum punctatum, of a pale green colour ; and the apophyses are the 

 largest of any British Splachnum, glossy, dark brown. 



7. S. Frcelichidnum, Hedw. {Frwlichian Splachnum); leaves 

 elliptical very obtuse, their nerve disappearing below the sum- 

 mit, apophysis obovate much narrower than the capsule, teeth 

 of the peristome 16 geminate erect when dry. Hedw. St. 

 Cr. v. 3. t. 40. Hobs. Brit. Mosses, v. 2. n. 12, (exotic 

 specimens). Muse. Brit. ed. 2. p. 41. t. 9. — S. reticulatum, Fl. 

 Brit. p. 1177. E. Bot. t. 2507. — Dissodon Frcelichianum, Grev. 

 et Am. Tent.Meih. Muse. 3. p. 122. — Bryum reticulatum, Dicks. 



On Ben High, Aberdeenshire. Mr. Dickson. Fr. Summer. — In habit 

 and in the remarkably obtuse leaves more allied to Splachnum scabrisetum, 

 {Hook. Muse. Ex. t. 32.), Systylium splachnoides, Hornsch., and Weissia 

 splachnoides, Schwaegr., than to the other species of the present Genus. 

 Messrs. Greville and Arnott, observing that the teeth of the peristome 

 in this groupe were erect (not reflexed) when dry, united them into one 

 Genus, Dissodon. But these do not all agree in other respects in the 

 configuration of the peristome. In S. Frcelichianum, although the teeth 

 do not become reflexed, yet they are 16 and geminate, or 8 double teeth 

 split through the middle, each single tooth too is destitute of a central 

 line. Systylium, Dr. Hornschuch still considers sui generis. Weissia 

 splachnoides Mr. Brown had previously called Cyrtodon, but rather as a 

 subgenus, than a genus in itself: yet this, as most different in the nature 

 of its peristome, I incline to retain ; though at the same time I must 

 acknowledge that it would be more accordant to nature, and simpler 

 in practice, to rank them all under Splachnum.
