248 BRYACE^. [Mnium. 



Hab. Shaded banks, on buiuus; roots of trees. Very rare in fruit. 



Scliimper says (Syn. ed. 2, 487), that fruiting specimens of M. Blyttii, 

 found by Dr. Kiter in Dovrefield, jSTorway, oblige him to unite tliat species 

 to M. stellare, from which it differs merely in its more compact tufts and 

 higher stems. 



17. M. cinclidioides, Hueben. Dioecious : plants large, 

 loosely cespitose, bright green and shining when young, blackish 

 when old, the sterile branches with larger leaves ; stems dark 

 brown : leaves remote, large, the lower inserted only by the 

 dilated base of the costa, round-ovate or exactly oblong, the 

 upper and comal broadly lingulate, rounded and slightly emar- 

 ginate at the apex or shortly apiculate, deej^ly undulate ; outer 

 perichaitial leaves spatulate, the inner small and lanceolate ; 

 costa gradually narrower upward, vanishing below the apex ; all 

 the leaves thin, subscarious, soft, scarcely changed when dry ; 

 areolation obliquely oval, loose : capsule on a long slender 

 pedicel, abruptly j^endent, ovate ; lid convex, ajDiculate or acu- 

 minate. — Muse. Germ. 416 ; Bryol. Eur. t. 402. 



Hab. Bogs, in New England {Eaton, Ingraham, James). 



* * * * Leaves margined^ very entire. 

 -I— Lid rostrate. 



18. M. punctatura, Hedw. Dioecious: plants in loose 

 dark or yellowish green tufts ; stems rigid, covered tip to the 

 fruit-bearing apex with dark brown rootlets : branch- and stem- 

 leaves remote, open or reflexed, large, the lower round-ovate, 

 narrowed to the base, inserted by the enlarged costa ; the u])per 

 rosulate, 4 to 6, broadly ovate-spatulate, surrounded by a brown 

 hard thick margin, subemarginate and apiculate at the summit ; 

 costa purplish, abruptly vanishing near the apex: male plants 

 more slender, with scarcely any stem-leaves: capsule oval, 

 mostly solitary, horizontally inclined, green when ripe ; lid 

 acutely beaked. — Spec. Muse. 193 ; Bryol. Eur. t. 387. 



Hab. Cold springs and borders of brooks, on mountains; rarely 

 fruiting. 



Besides var. elatum, Bruch & Scbimp., whose robust stems are 12 to 15 

 cm. long, local varieties are often noted. Specimens from Alaska have 

 the leaves bordered by a thick broad dark orange margin. 



19. M. SUbglobosum, Bruch & Schimp. Synoecious : 

 appearing at first sight like a more compact form of 31. punc- 

 tatum^ with slender densely tomentose yellowish brown stems 

 and small leaves, but differing essentially in its bisexual flowers
