Dioicous ; in crowded gregarious tufts, olive green above, reddish 

 brown below, not unfrequently scorched at tips, somewhat glossy ; 

 stems i 2 in. high, rigid, erect, dichotomous or fasciculate, tomentose 

 with scattered radicles. Leaves erecto-patent, subimbricate when dry, 

 lanceolate-subulate, channelled, uppermost broader, the margin inflexed 

 and semitubular toward apex; nerve about f width of base, lamelligerous 

 at back, ending in a diaphanous strongly spinuloso-denticulate hair- 

 point, below of 4 strata of cells, the anterior one larger and empty ; the 

 rest chlorophyllose ; basal cells hyaline, hexagono-rectangular, passing 

 obliquely toward margin as they ascend, angular cells few large brown, 

 above small, chlorophyllose, obliquely rhomboid-oval. Perich. bracts 

 convolute, oblong, subulate at apex with the narrow excurrent nerve, 

 cells thin elongated pellucid ; capsules aggregated, seta short, flexuose, 

 pale brown ; capsule oval, rather unequal, olivaceous, smooth, 

 transversely rugulose and darker at base, lid oblique rostellate, fuscous ; 

 peristome orange red. 



Male plant short, simple, the inflorescence in a capitulum, inner 

 bracts colored, broad, convolute, with short points, nerve obsolete. 

 HAS. Heaths, stony ground and rocks ; not common.

The discovery of the fruit of this plant near Oporto by Mr. Isaac 

 Newton in 1879, confirms the accuracy of its reference to the tropical C. 

 introflexus, the only difference we find being that in the European forms the 

 arista is straight, but in the southern it is generally reflexed at an angle 

 from the lamina ; the chief peculiarity of the species is seen in the male 

 plants, in which the leaves on the innovations are quite short and lax, 

 gradually becoming more elongated and crowded to the coma, and thus 

 strongly resembling a Polytrichum, e.g., P. pilife mm.
