206 HANDBOOK OF BRITISH MOSSES. 



On banks, trunks of trees, stones, etc. Bearing fruit, but 

 rarely, in early summer. 



Forming dense, pulvinate, bright-green tufts, which in the 

 place of fruit frequently produce numerous cylindrical pedun- 

 cles, surmounted by radiating, broadly fusiform, apiculate, 

 3-4-septate gemmae ; upper leaves more elongated ; leaf- cells 

 rotundo-hexagonal, projecting on either side, the walls evidently 

 distinct from each other, and not confluent. 



The gems were formerly taken for the male blossom, whence 

 the erroneous name androgynum. 



2. A. palustre, Schwceg. ; dioicous ; stems radiculose, irre- 

 gularly dichotomous ; leaves oblongo-lanceolate, erecto-patent, 

 waved, twisted when dry, papillose, toothed at the apex ; 

 margin reflexed ; sporangium oval, incurved. Hook, fy Wils. 

 t. xxviii. ; Eng. Bot. t. 391.; (Plate 18, fig. 5); Moug. %

 are occasionally produced, but not so frequently as in the last 

 species.
