74 DESCRIPTION OF TROCHOPTERIS. 
dozen kinds of Anemia. All of these, with perhaps two or ` 
three exceptions, are undescribed species. Two of the Ane- - 
mie are very remarkable from the very great subdivision of — 
their barren fronds, those of one of them—Anemia Millefo- 
lium, Gard. MSS. No. 4083—very much resembling the 
leaves of Achillea Millefolium. Figures and descriptions of 
this and the other species—A. dichotoma, Gard. MSS. No. 
4084—will shortly appear in the forthcoming number of 
Hooker's Icones Plantarum. The greater part of these were ` 
found on the Serra de Natividade, a rocky mountain range | 
nearly destitute of wooded vegetation, which rises about . 
2000 feet above the level of the plain in which it is situated.
