HISTORY OF INTRODUCTION OF EXOTIC FERNS. 33 
in British Guiana, and also on the banks of the 
Orinoco, Rio Negro, and Yapura rivers. Several 
other species of Schizsea are likewise worthy of a place 
in our gardens, such as the pretty Schizcea pectinata 
of the Cape of Good Hope, and Schizcea ciichotoma, 
which is found not only in Guiana and Venezuela, but 
widely dispersed through the Pacific islands as far 
south as New Zealand, occurring also in Java, Mysore, 
the Mauritius, and other parts of the Eastern hemi- 
sphere. Allied to these, also, are the two Brazilian 
species of Goptopliyllum described by Dr. Gardner, 
and likewise the Trochopteris elegans of the same 
author, all of which some pteridologists include under 
the genus Anemia, and perhaps rightly so with respect 
to the former, for they have the same relationship 
with true Anemia that Osmunda cinnamomea has 'with 
0. regalis, their barren and fertile fronds being dis- 
tinct. Both species are found in the province of 
Goyaz ; one being named C. millefolium and the other 
C. buniifolium, from the general resemblance in the 
divisions of their barren fronds to the leaves of 
Achillea millefolium and Bunium. The Trochopteris 
elegans is an exceedingly curious little Fern, with flat, 
radiating fronds of a somewhat spathulate form but 
more or less five-lobed, the two lower lobes being 
deeper and bearing the sporangia, the entire plant 
resembling a rosette, and growing on rocks like a 
lichen. Dr. Gardner found it on the Serra de Nativi- 
dad, in the province of Goyaz. Amongst other Bra- 
zilian Ferns worth being looked after, I may mention 
two species of Antigramme — A. Srasiliense and A. 
Douglassii, the former having oblong-lanceolate fronds 
about a span long, tapering downward to a short
