RECENT ADDITIONS TO OUR MOSS FLORA. 391 



three strata of cells, the two anterior larger and empty. Lamina ex- 

 tending to apex ; the cells at base thin and fragile, enlarged, hyaline 

 in the young leaf becoming fuscous when old, above these rectangular 

 in 14-16 longitudinal rows, gradually incrassate and quadrate toward 

 apex. In some tufts the stems terminate in a rosette of ovate leaves 

 with short points, and more distant elliptic cells. These are pro- 

 bably male plants, but I have not succeeded in finding antheridia. 

 — liab. Peaty soil, with D. Jieteromalla, in Trickley Eir Wood, on the 

 top of Whiteside Hill, near Wooler, Cheviots (Messrs. Boyd and 

 Hardy, 1868). Although differing much in appearance from C.fiexu- 

 osus this Moss closely resembles it in structure, and may perhaps be 

 not specifically distinct. The dull green colour, compact tufts, with 

 shorter, denser leaves, and the lamina tapering more gradually to the 

 apex, are the chief points presented by C. paradoxus, for the areolation 

 of the two is almost identical. 



8. C. setifoUus, Wilson, Bry. Brit. p. 89 ; Schpr. Muse. Eur. Nov. 

 fasc. 3 and 4. — In lax, soft, irregular tufts, bright green or silky 

 yellowish-green above, blackish below, without radicular tomentura. 

 Stems 5-10 in. long, geniculate, erect, slender, dichotomous. Leaves 

 distant, erecto-patent or subsecuud, glossy ; very long from a 

 lanceolate base, gradually running into a long subula, subtubular con- 

 cave, not unfrequently half twisted ; uppermost with the wings ser- 

 rated. Nerve more than half width of base, passing into a rough 

 arista forming the subula, smooth at back, composed of three strata of 

 cells, the posterior being minute and chlorophyllose, the middle of 

 same size but hyaline, the anterior twice the size and hyaline. Au- 

 ricles very large and inflated, the cells partly fuscous, partly hyaline, 

 hexagonal, above these hexagono-rectangular, the upper rhombic and 

 chlorophyllose with thick walls. Flowers of each sex collected in ca- 

 pitula ; males 3-4, females numerous. — Hab. W^et places among 

 grass and heath and in clefts of rocks. Gap of Dunloe, Killarney 

 (Schimper). Sligichan, Skye (Hunt).

 C. auricidalns, W^ilson, ms. — In dense soft silky yellowish-grccn tufts, 

 brownish below, free from radicular tomentum. Stems 2-3 in. high, 

 slender, repeatedly dichotomous ; leaves erecto-patent, straight or very 

 slightly secund, those at base lanceolate, the upper lanceolato-subulate 

 and subtubular, entire at apex, the base somewhat sheathing, with
