Hab. — Among grass, by the shady sides of streams. 



England : Darnhohii, Goathland, Yorkshire (Braithwaite) ; about Ulverston, 

 Lancashire (Miss Hodgson) ; Barbon Fell, Westmoreland (Barnes) ; Penzance, 

 Cornwall (Curnow). 



What I assume to be this variety grows in loose tufts, having 

 large flexuose branches, and large somewhat divergent leaves with 

 a slight gloss. 



15. Sphagnum Wulfii, Girgensoiin. 



Pl. XXII. 



Monoicous ; robust, more or less '"ascent, the stem with two 

 layers ol" cuticular cells. Stem leaves small, dilated at base, 

 Ungulate, rather acute, without fibres or pores. Branches 7-12 in 

 a fascicle, their leaves ovato-lanceolate, erecto-patent, with three 

 minute teeth ; chlorophyllose cells central, oval or rectangular in 

 section.

Monoicous ; robust, yellowish or brownish green, or soinetimes 

 deep green, in loosely cohering tufts. 



Stems 5-12 in. high, simple or sometimes divided, blackish 

 brown, solid, densely ramulose ; cells of the peripheral zone purple, 

 in 5-6 layers, strongly incrassate; cuticular cells in two strata, 

 small, non-porose. Stem leaves small, from a broad base, liiigul *"e- 

 triangular, reflexed, rather acute, eroso-subdenticulate at apex ; the 

 hyaline cells repeatedly divided, without fibres or pores, those in 

 the middle rhomboidal, becoming narrower towards the margin, 

 where they form a border of 3-6 rows. 



Ramuli 7-12 in a fascicle, 3-5 divergent, short, slightly arched, 

 becoming clavate upward and then suddenly pointed ; the rest 

 deflcxed and closely appressed to stem, very long, slender and 

 filiform, lax-leaved, often of a pale rose colour ; the porose cuti- 

 cular cells short and scarcely differing from the rest. Branches 

 of the coma short, thick, and numerous, forming a large dense 

 capitulum.
