Dioicous ; gregarious, glaucous green above, fuscescent below ; 

 rhizome flexuose, densely radiculose. Stem erect i 6 in. high, rarely 

 2 or 3 partite. Leaves when moist patulous and subrecurved, when dry 

 erect, the lower squamose, appressed, the upper long, lineal-lanceolate, 

 semiterete-subulate, the wings inflexed, subconnivent, quite entire, 

 nerve excurrent in a short reddish arista, muricate at back; lamellae 

 yellow-green, low, dense, about 48, each in section of a row of 4 6 cells, 

 the marginal one larger, cruciform from having a tooth-like papilla at 

 apex. Perich. bracts longer, convolute, membranous at margin, with a 

 long rough arista. Capsule on a purple seta, entirely covered by the 

 rufous calyptra, tetragono-prismatic, erect, pachydermous, rufous- 

 orange, finally brown and horizontal, with a purple shield-like 

 hypophysis; lid plano-convex, rostellate, rufous with a deep red margin. 

 Teeth 64, rather short, pale yellowish. 



Male plants intermixed, more slender, with shorter leaves; outer 

 bracts ovate, strongly mucronate, innermost thin, truncate, pointed. 



HAB. Wet heaths and bare places in woods ; not uncommon. Fr. 6 7. 



This plant varies much in size and also in the colour of the calyptra, 

 which at great elevations is sometimes quite white. 



Dillenius by some mistake has figured the leaf as serrated, and the plant 

 in his herbarium is P. strictum $ .

Dioicous ; resembling P. juniperinum but taller, and more slender 

 with densely tomentose stems; the leaves shorter, erecto-patent, 

 straight. Capsule small, cuboid. (T. VIII, C.)
