Monoicous or sometimes dioicous ; in soft tufts, pale green, 

 usually more or less tinged with purple. Stems slender, dichoto- 

 mous, pale ; cuticular cells gene-ally without pores, in 3-4 strata ; 

 cells of the peripheral layers incrassate, purple. Stem leaves 

 erect, ovato-acuminate, concave, with the margin incurved, minutely 

 auricled at base, 5-toothed at apex ; hyaline cells of the middle 

 base hexagono-rhomboid, with one or two oblique partitions, 

 without fibres or pores, the upper also divided, and often slightly 

 fibrillose, lateral very narrow and forming a broad border, 

 gradually decreasing in width toward apex. 



Ramuli 3-5 in a fascicle, 2-3 arcuato-divergent, 1-2 pendent, 

 filiform, all more or less attenuated at points ; their retort cells 

 flask-shaped, subcylindric, perforated and slightly recurved at apex. 



Ramuline leaves minute and ovate at base, median ovato- 

 lanceolate, erecto-patent, deeply concave, uppermost narrowly 

 lanceolate, all toothed at the slightly truncate apex, and with the 

 margin involute in the upper third ; hyaline cells confluent at back, 

 with a few large pores and annular fibres, those of the upper half 

 of leaf much smaller, more densely fibrose, and with smaller pores ; 

 border extremely narrow, of two rows of long thin cells ; chloro- 

 phyllose cells obtusely trigonous, interposed between the hyaline 

 at the concave surface of leaf. 



Capsules numerous, usually clustered in the capitulum ; pe- 

 duncle moderately elongated, the bracts numerous, straw-coloured 

 or reddish, lowest broadly ovate, acuminate, concave, median 

 oblong, narrowed at apex, uppermost elongated, convolute ; the 

 hyaline cells narrower and more solid than in the cauline leaves, 

 with 2-3 partitions, but no fibres or pores. Spores ferruginous. 

 Male inflorescence purple, in clavate acute amentula ; the bracts in 

 five rows, ovate, acute. 



Hab. — Heaths and bogs, forming loose cushions. Common throughout Europe 

 and North America. Fr. July.
