THE SPHAGNACE^E OR PEAT-MOSSES OF 



1 



Capsules numerous, seated in the capitulum, moderately elevated. 

 Pericha;tia large, inflated ; the bracts yellowish green, lower elon- 

 gated oblong, upper broadly obovate-oblong, convolute, truncate 

 and fimbriate at apex, transversely undulate at base, without fibres 

 or pores. Spores yellow. 



Male inflorescence consisting of few antheridia, which are borne 

 on the pendent branches. 



Had. — Deep bogs in the north. Fr. July. 



Europe. — Near Lakes Betsctjaur, Skatijaur, and Storavaviken, in Pitean Lapland 

 (Lindberg, 1856); pretty generally distributed in other parts of Lapland, as well as 

 in Finland and the north of Sweden; Dovrefjeld, Norway (Bcrggren); in the 

 Riesengebirge, Silesia; Wcisse Wiese (Sendtner, 1838); Kleiner Teich, Pantsche 

 Fall ; Elbwiesen ; Gr.' and Kl. Schneegrube (Milde) ; Alps of Salzburg (Sauter). 

 Ben Wyvis, in Ross-shire, Scotland (McKinlay, 1867); north end of island of 

 Unst, Shetland (Sim, 1878). 



N. America. — Newfoundland; Canada (Drunimond), and also in Greenland. 



This fine species closely resembles Sph. intermedium in ap- 

 pearance, but is easily distinguished by the very different stem 

 leaves, and the non-undulatcd branch leaves, unaltered by drying, 

 as well as by the glossy ferruginous tint ; it is also much more 

 robust, and by the areolation comes near the subsection acntifolia. 

 It does not appear to be subject to any variation except in the 

 shades of colouring ; but the Scotch specimens are very small in 

 comparison with those from Lapland.

Pl. XXIV. AND XXV. 



Dioicous ; robust. Cuticular cells in 2-3 strata, small, thin, 

 and indistinct. Stem leaves ovato-triangular, without fibres or 

 pores, broadly bordered with narrow elliptic cells. Pendent branches 

 closely appressed to stem and concealing it. Branch leaves densely 

 imbricated, broadly lanceolate ; the margins undulate and points 

 recurved when dry. Spores yellow.
