CHARACTERS OF TRIBES AND GENERA. 353 
Oss.—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 (Amemidictyon), those with 
the sterile and fertile fronds wholly distinct I added to the 
genus Mohria 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 Filieum " 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 
Periana, a native of Abyssinia, and 4. Dregeana, a native of 
South Africa, the whole are natives of the West Indies and 
: Tropical and Sub-tropical America.
