Sphagnum.] MUSCl-ACRdCARPl-GYMNOSToMI. O 



naked. Calyptra irregularly torn. (Muse. Brit. t. 1.) — Name 

 applied by Dillenius to this Genus of Plants. The Sphagnum 

 of Pliny is some kind of tree-moss or lichen — The species 

 are all aquatic and remarkable for the beautiful texture of 

 their leaves and for their pale almost white colour, especially 

 when dry. 



1. S. obtusifolium, Ehrh. (blunt-leaved Bog -Moss) ; branches 

 tumid, leaves ovate obtuse. Muse. Brit. p. 13. t. 4. — x. vulgaris, 

 stems loosely tufted, 7 or 8 inches long, leaves closely imbri- 

 cated. Ehrh. Or. n. 241, (according to Sm.) Brum. Muse.

 bifolium, Sic. (to which may be added probably S. contort inn, 

 Scludtz and S. subsecundum, Nees ; and many species of Bridel.) 

 — S. palustre, a. Linn. — Bill. Muse. t. 32. /. 1. — 0. minus, stems 

 densely tufted 2 or 3 inches long, leaves closely imbricated. S. 

 com pactum, Schwaegr. Sitppl. v. 1. t. 3. Bryol. Germ. v. 1. 

 p. 13. t. 2. /. 5. (excellent). — y.fluitcins, stems much length- 

 ened out, 2 to 3 feet long slender, leaves scattered remote. 

 S. latifolium, /5. fluitans, Turn. Muse. Hib. p. 6. — S. immersum, 

 Bryol Germ. v. I. p. 11. t. 2./. 4. 



Bogs and still pools, in heaths and moory soils, every where most 

 abundant. Fr. Spring. — Linnaeus was perhaps correct in supposing that 

 there was but one species of Sphagnum: for I think that from the 

 var. a. of S. obtusifolium, the most decidedly marked of the broad-leaved 

 state of the Genus, a regular gradation may be traced to S. cuspidal urn, 

 which has the longest and narrowest leaves. It is very certain that 

 the limits of the species, if such they may be called, cannot be defined. 

 Bridel enumerates 16 species. 



2. S. squarrosum, Web. et Mohr. (spreading -leaved Bog- 

 Moss) ; branches attenuated at the extremities, leaves ovato- 

 acuminate squarrose recurved. Web. et Mohr, It. Suee. t. 2.f. 1.

 ed. 2. p. 1 3. t. 4. 



Bogs; not rare. Fr. June. — Separated from the last on account of 

 its more acuminated, and, at the extremities, recurved /caves. 



3. S. acutifdlium, Ehrh. (slender Bog-Moss) ; branches at- 

 tenuated, Leaves ovato-lanceolate crowded. Ehrh. Or. n. 72.
