1. L. linearis (linear), Swartz.; Hook. Spec. Filic.i. 206, Syv. Fil. 104; 

 Benth. Fl. Austr. vii. 719. Rhizome creeping. Fronds simply pinnate, the 

 stipes and the rhachis wiry, black and glabrous, from 2 or Sin. to above 1ft. bigh, 

 very fragile. Pinnules distant, very obliquely cuneate or flabellate almost 

 dimidiate, the base very unequal, 3 to 4 lines broad. Sori forming a continuous 

 line under the outer margin. — R. Br. Prod. 156 ; Hook. f. Fl. Tasm. ii. 136 ;

Hab.: Brisbane Eiver, Moreton Bay, F. v. Mueller, Bailey ; Nerang, Schneider; and Stanthorpe. 

 Also in New Zealand, New Caledonia and Norfolk Island. 



2. Ii. dimorpha (of 2-forms), Bail. Ql. Ferns, 19 ; Benth. Fl. Austr. vii. 

 719. Rhizome tufted. Fronds simply pinnate, the barren ones mostly 2in. long 

 or rather more, with a few broad flabellate pinnules, toothed and shortly lobed, 

 scarcely oblique. Fertile fronds much longer, the stipes and rhachis very slender 

 and pale-coloured. Pinnules either broadly flabellate very oblique and undivided 

 as in L. linearis or once or twice bipartite as in L. incisa. — Bail. Litho. Ferns Ql. 

 51 ; L. heterophylla, Prent. in Trim. Journ. Bot. 1873, 295, not of Dryand. 



Hab.: Eight Mile Plains, Prentice ; Glass-house Mountains and Kedron Brook, Bailey.

 105 ; Benth. Fl. Austr. vii. 719. Rhizome tufted or very shortly creeping. 

 Fronds simply pinnate, 3 to 6in. long, the stipes and rhachis wiry but slender 

 and pale-coloured. Pinnules near together, occupying the greater part of the 

 frond, very oblique or half reniform, 8 to 4 lines broad, the rounded outer margin 

 entire, with the sorus and indusium continuous or slightly lobed or denticulate 

 interrupting the sori. — Hook, and Grev. le. Filic. t. 144 ; Bedd. Ferns S. Ind.

 Fl. Austr. vii. 720. Rhizome creeping. Fronds 6in. to 1ft. high, usually 

 bipinnate 2 or more of the lower pinnas being again pinnate and 2 to 4in. long, the 

 upper pinnsB entire but sometimes the whole frond simply pinnate or in other 

 specimens more or legs tripinnate. Pinnules oblique, in the simply pinnate part 

 flabellate or almost rhomboid often ^in. broad, smaller in the more compound 

 specimens. Veins forked, free or rarely here and there anastomosing. Sori 

 continuous round the margin or interrupted. — Bail. Litho. Ferns Ql. 53 ; L. Unera,
