DICRANEI. 273 



Of this species, which has not yet been found in fruit, I have 

 seen no specimen, and therefore copy Mr. Wilson's character. 



4. C. flexuosus, Brid. ; tufted ; stem radiculose, branched ; 

 leaves crowded, spreading or secund, lanceolato-subulate, 

 rather rigid, obsoletely furrowed at the back ; nerve broad ; 

 sporangium oblong, wide-mouthed; teeth slightly spreading 

 when dry. — Hook. &; Wils. t. xvi. ; Eng. Bot. i. 1491. ; (Plate 

 23, fig. 4.) 



On the ground and on rocks, mostly in subalpine countries. 

 Bearing fruit in November. 



Forming olive-green patches, reddish below. Leaves 

 broader and longer, not deciduous as in C. fragilis ; leaf-cells 

 small, distinct, subquadrate or elliptico-oblong above, rectan- 

 gular and more lax below. Moug. & Nest. n. 123 appears to 

 be C. densus, and has very different leaf-cells from this, being 

 narrow and elongated. 



5. C. longipilus, Brid. ; csespitose; stem elongated, rigid, 

 dichotomous ; leaves erecto-patent, lanceolato-subulate, con- 

 volute, suddenly ending in a white bristly point; nerve very 

 broad. — Hook, fy Wils. t. xl. 



On wet rocks and in marshy places in mountainous districts. 

 Forming black-green hoary tufts. Leaf-cells oblong and 

 narrow, enlarged at the base. Perfect fruit unknown. 



6. C. polytrichoides, D. Not. ; loosely tufted ; stem stout, 

 elongated, slightly branched, naked below, slightly radiculose; 

 leaves erect, broadly lanceolato-acuminate, channelled, shortly 

 hair-pointed, and slightly toothed above ; nerve stout, broad, 

 subexcurrent, deeply sulcate behind, sublamellate. 



In dry pastures. Penzance. Fruit unknown. 



Bright-green above, rufous below. Leaves much broader. 

 The above is taken from the Syllabus of De Notaris, as I have 

 seen no specimens.
