Has. Among the débris of schistose rocks on the summit of 
the Serra de Natividade, in the north of the province of 
Goyaz, Brazil. 
This and the following elegant little Fern, I have separated 
from the genus Anemia, principally on account of their fertile 
fronds rising distinctly from the rhizoma; and being in no way 
connected with the stipes of the barren fronds. This latter 
circumstance characterizes the true Anemias, for in them the 
frond which bears the spikes of fructification is formed by the 
union of two fertile fronds with one barren one. Since mY 
papers in the Journal of Botany were written, I have examined — 
the anatomical structure of the fertile frond of Anemia Phylli-- 
tidis, Sw., and I find that three nearly distinct bundles of 
annular ducts can be traced to the top of the stipes, where they — 
at last separate, one running into the barren, and one into — 
each of the fertile portions. Link, I find, entertains similar 
views on the structure of Anemia.—G. Gardner. |
