Sori indusiate, linear, continuous, on a broadish linear recep- 

 tacle, occupying nearly the whole under surface of the contracted 

 fertile fronds. Indusium attached at the margin, linear, conti- 

 nuous, scarious, opening along the inward side. Veins (sterile): 

 simple or forked from a central costa, the venules direct, free ; 

 or (fertile) obsolete. 



Fronds simple pinnatifid pinnate or bi-pinnatifid ; the fertile 

 contracted. Rhizome short, thick, erect or decumbent, rarely 

 creeping or arborescent. This genus is technically very nearly 

 allied to Blechnum, its typical species differing in having the sori 

 and indusia at the margin, whilst in Blechmim they are distinctly 

 intramarginal ; but there are some species in which these differ- 

 ences are not very obvious. L. Fraseri, which has a slender 

 arborescent trunk -like rhizome, is an anomalous species, ap- 

 proaching Onychium, but wanting the pinnate veins of the fertile 

 segments which occur in that genus.
