There is so much difference of opinion amongst Botanists 

 regarding Alsophila, Cyathea, and Hemitelia, that different Au- 

 thors place them in a different genus; thus the Hemitelia 

 Hostmanni of Hooker is Alsophila Hostmanni of Smith, and 

 the Hemitelia horrida of R. Brown is the Cyathea horrida of 

 Smith. Mr. Moore places many of them in Alsophila and Am- 

 phicosmia; perhaps some day they will all be united in one 

 genus.
