referred by Mr. Horrell {European Sphagnacecp, p. G7) to S. 

 fescejis. if this be so it would come under var. parvulum Warnst., 

 but the specimen is gummed down and cannot be examined. 

 {b) Chyandal Moor, Cornwall, Curnow, is S. rufescens Warnst. var. 

 onagnifolium Warnst. f. rufidulum Warnst. subf. densiramosum 

 Warnst. 



17. S. sulsecundum var. contortiun. {a) Goathland, Yorks, 

 Andei'son ; I think after a very partial examination that this is a 

 form of /S. havaricum Warnst. v'dv.7?iesophi/llu)n Warnst. (h) forma 

 .rufescens. Sleights Moor, Yorks, Anderso7i, Only two stems, both 



gummed down, of this interesting looking specimen. 



18. S. subseciindtun var. ohesum. (a) Cornwall, Ciirnoiv, is 

 • S, turgidulum Warnst. var. insignitum Warnst. (5) Sleights Moor, 

 .Yorks, Ande?^son, is >S'. rufescens Nees var. magnifolium AVarnst. 



f. rufidulum Warnst. 



19. /S'. suhsecundum var. auriculatum. (a) Sutton Park, War- 

 wickslnre, Bagnall^ is 8. rufescens Nees f. virescens Warnst. {h) 

 Delamere, Cheshire, Whitehead, is S. rufescens Nees var. parvulum 

 Warnst. f. gracile Warnst. (c) Staveley, Westmorland, Barnes, is 

 S. auriculatum Schimp var. laxifolium Warnst. 



20. S. suhsecundumY^Y. auriculatum i. immersum. (a) Withers- 

 lack Moss, Westmorland, Barnes, appears to be an undescribed form 

 of *S^. auriculatum Schimp. Var. laxifolium Warnst. f. immersum 

 (Braithw.) Wheld. Very lax, elongate, green, and floating, about 

 20 cm. long, with small, indistinct capitulum. Br. distant, upper 



-shorter (5-6 mm.), their leaves spreading, lower up to 10 mm. long, 

 with more imbricate leaves. St. 1. large (1"5 x *7--8), fibrose above, 

 rarely to base, externally with many ringed pores, internall}^ with few 

 pores, chiefly in cell angles, cells often septate, (h) Lindon Common, 

 Cheshire, Whitehead, is S. crassicladum Warnst. var. intermedium 

 Warnst. f. ovalifolium Warnst. 



21. S. molle Sull. var. Mulleri, Goathlanddale, Yorks, Ander- 

 son, is the average British S. molle Sull. var. molluscoides Warnst. f. 

 heterophyllum Warnst. ; it does not come under any of the subforms 

 which Warnstorf describes and may be distinguished as follows : — 

 subf. typicum Wheld. Branches cumulate, less dense than in 

 subf. tenerum (Br.) Warnst. in larger and taller tufts, leaves erect, 

 less closely imbricate. 



21*. h. molle Sull. var. arctum. (a) Witherslack Moss, West- 

 morland, Barnes, (b) Connemara, Galwa}^ D. Moore. These are 

 gummed down and the material is too scanty for removal and exami- 

 nation, but neither is S. molle : probably forms of S. rubellum 

 or S. acutifolium. (c) Dalfroo Bog, Kincardine, J. Sim, is S. molle 

 Sull. var. molluscoides Warnst. f. hetrrop)hgllum Warnst. subf. 

 . tenerum Warnst. It is distinguished from subf. typicum Wheld. by 

 its much denser usually anoclade branches, smaller tufts, and its 

 smaller and moi-e closely imbricate leaves. 



23. S. rigidum (Nees), Petworth, Sussex, G. Davies, is >S'. com- 

 pactum DC. var. subsquarrosum W. f. densuni Warnst. 



21. S. rigidum var. squarrosum, Langdale, Westmorland, Barnes, 

 is a paler form of the preceding.
