Nilghemes and the Straits of Magellan. Of the other species 

 some are tropical, while others, as M. eriocaula (Fig. 4), 

 belong to the more equable temperate regions. This is re- 

 ferred by Mitten, together with, M. prehenailis and Aneura 

 multijida, to Sarcomitrium. The tribe would, perhaps, be 

 better united with Haplolamece.
