Oss.— The first is a native of South Brazil, and the other 
very generally distributed throughout the West Indies and 
Tropical America. As might be expected, the plants of the 
different localities have been described under no less than 
ten specific names, their differences resting entirely on the 
: difference of length and breadth of the sterile pinne, which, 
| _ although retained under cultivation, I do not vonsider it a 
| sufficient character to be specific.

Oss.— This is a peculiar little Fern, a native of Brazil, 
growing on the face of rocks. The fronds lying flat, their 
appearance led Dr. Gardner to compare them to little 
. Wheels. It may be considered to be a modified state of 
Anemia, but its distinct habit is sufficient to mark it as a 
Separate genus.
