HISTOKY OF INTfiODUCTION OF EXOTIC FEENS. 33 



in British Guiana, and also on the banks of the 

 3rinocOj Rio Negro, and Yapura rivers. < Several 

 Dther species of Schizeea are likewise worthy of a place 

 n our gardens, such as the pretty Schizcea peetinata 

 jf the Cape of Good Hope, and Schizcea dichotoma, 

 ivhich is found not only in Guiana and Venezuela, but 

 ifidely dispersed through the Pacific islands as far 

 south aa New Zealand, occurring also in Java, Mysore, 

 ;he Mauritius, and other parts of the Eastern hemi- 

 sphere. Allied to these, also, are the two Brazilian 

 species of CoptophyUum described by Dr. Gardner, 

 md likewise the Trochopteris elegans of the same 

 luthor, all of which some pteridologists include under 

 ;he genus Anemia, and perhaps rightly so with respect 

 ;o the former, for they have the same relationship 

 srith true Anemia that Osmunda cinnammnea has with 

 5. regalis, their barren and fertile fronds being dis- 

 ;inct. Both species are found in the province of 

 jroyaz ; one being named 0. millefoUv/m and the other 

 7. buniifolium, from the general resemblance in the 

 iivisions of their barren fronds to the leaves of 

 Achillea millefolium and Banium, The Trochopteris 

 ilegans is an exceedingly curious little Fern, with flat, 

 •adiating fronds of a somewhat spathulate form but 

 nore or less five-lobed, the two lower lobes being 

 ieeper and bearing the sporangia, the entire plant 

 ■esembling a rosette, and growing on rocks like a 

 ichen. Dr. Gardner found it on the Serra de Nativi- 

 lad, in the province of Goyaz. Amongst other Bra- 

 iilian Ferns worth being looked after, I may mention 

 iwo species of Anidgranvme — A. Brasiliense and A. 

 Oouglassii, the former having oblong-lanceolate fronds 

 ibout a span long, tapering downward to a short
