CHARACTERS OF TRIBES AND GENERA. 353 



OBS. This genus, as originally characterised by Swartz, 

 contains species differing, in some having their fertile 

 fronds wholly contracted, forming a panicle, and in others 

 the fertile frond is tripartite, one branch being always 

 sterile, the other two always fertile. In my " Genera of 

 Ferns," published in the "Journal of Botany" for 1841, I 

 restricted true Anemia to the species possessing the latter 

 character, a few of which, having anastomose venation, I 

 separated as a distinct genus (Anemidictyori), those with 

 the sterile and fertile fronds wholly distinct I added to the 

 genus Hohria of Swartz. Subsequent observation has, 

 however, induced me to alter this view, and to consider 

 them more nearly related to Anemia than to Mohria. 



Presl enumerates no less than forty species of Anemia, 

 which in the " Synopsis Filicum " are reduced to twenty- 

 six. A number are, however, termed varieties, the 

 numerous intermediate forms of herbarium specimens 

 naturally lead to such a conclusion. With the exception 

 of A. Wightiana, a native of the Neilgherries, A. Schim- 

 periana, a native of Abyssinia, and A. Dregeana, a native of 

 South Africa, the whole are natives of the West Indies and 

 Tropical and Sub-tropical America.
