 2-4 times divided into linear lobes, lower pinnules often tbe longest. S. nitens, 

 R.Br.

2. H. BARUM, R. Br. Leaf 2-4 inches, erect or nearly so, narrow, 2-3 times 

 divided, the lowest pinnules very short. 



Very common on tree-ferns. South-East Australia. 



3. H. JAVANICUM, Spreng. Leaves 3-5 inches, erect, much-divided, the rhachis 

 and stalk provided with an expanded pale green wing. M.Jlabellatum, R. Br. ;

 minutely and acutely toothed. Indusium orbicular, truncate, toothed. 



Common on mossy rocks, &c., in damp woods. In all temperate localities in

5. H. WILSONI, S. Plant hardly distinguishable from the last, only usually 

 rather smaller, the valves of the sori much longer than broad, and entire on the 

 margin. Some forms appear intermediate. 



Distribution similar. 



The Tasmanian plant is referred here, but its very small size and habit 

 hardly warrants it. 



6. H. MALiNGii, S. Leaf 1-2 inches high, 2-3 times divided. Ultimate 

 pinnules linear, clustered, the whole tomientose and grey. Receptacle a short 

 thick bristle, hardly protruding.

7. H. MAEGiNATUM, H. et Q. Leaves -j-f inch, simple, spathulate or with few 

 indefinite lobes, a marginal vein throughout. Sori at the tips of the leaves.

27.. SCHIZ.^A 



Sori collected on short linear pinnules, continuous and over-arched by the 

 margins. Pinnules gathered together in short comb-like masses on a long slender 

 stem. Barren leaves linear, simple or divided. Tufted habit. 



Pinnules 1 line long ... ... ... ... ... 1. S.Jistulosa. 



Pinnules usually 3 lines long ... ... ... % S. bifida. 



1. S. EISTDLOSA, Lab. Erect, 3-6 inches, undivided, filiform, the fertile leaves 

 bearing a comb-like end, f inch long, brown, with numerous linear curved 

 pinnules hardly 1 line long. Barren leaves simple, filiform. 



Widely spread in heathy country, but overlooked. Temperate Australia, 

 Africa, America, New Zealand, &c. 



2. S. BIFIDA, Will. Fertile leaves erect, 3-6 inches, simple, or once or twice 

 dichotomously divided. Comb-like process f inch long, usually greenish. 

 Pinnules slender, filiform, sometimes divided, straight, the lowest often longest, 

 crowded, mostly 3-4 lines long. Barren leaves filiform, usually many times 

 dichotomously divided. Sometimes combined with /S. dichotoma, Sm., but very 

 different in habit and detail. 



Widely distributed, in heaths, principally in the north ; easily overlooked. 

 Southern, Eastern, and Northern Australia to New Zealand.
