The j^eneric position of tliis peculiar little moss is somewhat doubtful. In 

 liubit it somewhat resembles Mktenia, but there tbe inflorescence is terminal. 

 In outward appearance it perhaps resembles more than anythin^v else fra^^-- 



mentary stems oF certain s[)ecies oE Puuiatella with orbicular complanate 

 leaves^ and the nerve^ and celUstructures are also uoi unlike. The position 

 of the pcricha}tinnij and the structure of tlie bracts, liowever, leave little 

 doubt that it belojigs to lUdzogoniuin (or possibly to a new and albVd genus). 

 The only species at all approaching it in size known to me is li.vallU-gratlai 

 (Ham[)e) from South Africa, which plant is, however^ of a totally ditferent 

 nature.
