flexuosus in fruit (Capt. Hutton 1865) ! Eagle's nest, Pass of Dunloe and Kenmare 

 Road, Killarney (Carrington and Hunt 1861) ! ! Kylemore Castle, Connemara (Moore 

 1870) ! ! Sligichan, Skye (Hunt 1863) ! ! Island of Lewis, Hebrides (Moore 1868) ! 

 Cwm Bychan near Harlech, in fruit (George 1878). 



The fertile plant is shorter and more densely leafy than the sterile or 



male, and the species is easily recognized by the large inflated auricles, and 



serrated hispid subula.

 Dioicous; in dense dark green cushions ; leaves lanceolate-subulate, 

 auricled, ending in rough white points. (T. XIX, B.)

Dioicous ; in dense silky cushions, lurid green or yellow-green 

 above, black below; stems slender, i — 5 in. high, repeatedly dichoto- 

 mous, dense-leaved, sparingly radiculose. Leaves gradually larger 

 towards apex, erecto-patent, lanceolate, canaliculate-subulate, straight; 

 nerve dilated, \ width of base, sulcate at back, excurrent in a long hoary 

 denticulate arista, in section of 4 strata of cells, the anterior and 

 posterior rather larger than the two median layers ; basal cells lax 

 subrectangular, those of auricles vesicular lax brown, upper oblong and 

 vermicular. 

 Hab. — Wet rocks and peaty ground on all our mountains ; common. Near 



Penzance [Cumow) ! ! 



Var. p. falcatus Braithw. 



Stem short, more robust ; leaves dense, broader, falcato-secund, cir- 

 cinate, very concave. 

 Hab. — Connemara [Pyof. Barker 1868) ! ! 



A form parallel to the variety of C. Shawii. The comal leaves of the 

 ordinary state are frequently more or less secund, and slender flagelliform 

 ramuli are also common. When the fragile hair points are lost, it is best to 

 examine the young apical leaves, on which they are usually retained, other- 

 wise there might be a difficulty in the determination of the species. 



II. CAMPYLOPUS INTROFLEXUS {Hedw.) Brid. 

 Dioicous ; olivaceous green, rigid ; leaves not auricled, lanceolate 

 subulate, terminating in a spinulose hoary point, basal cells hyaline ; 

 capsules aggregated, rugulose at base. (T. XIX, C.)
