however are longer and extend to the margin. The following 5 species — Aspl. nitidum, Sw. ; Aspl. cuneaturn, Lam. ; Aspl. ajine. Siv. ; Aspl. 
spathulinum, J. Sm. ; and Aspjl.laserjntUfolium, Lam. are all very closely allied, and it is no easy point to decide to which species any

Sori indusiate, short-oblong-lunate, or unequally or sometimes equally hippocrepiform ; the receptacles on the anterior or 
sometimes also crossing and returning along the posterior side of the veins. Ladusium of the same form, often lacerato-fimbriate. Veins 
simple or forked from a central costa ; venules free, sometimes pinnate. 
Fronds herbaceous, bi-tri-pinnate. Sori more or less generally, the basal ones usually rarely nearly all arcuate. Rhizome sliort, 
erect or creeping— although some or a greater portion of the sori are similar to those of Asplenium, the occurrrence of hippocrepiform 
sori, more or less numerous, sufHciently distinguishes this genus. {Moore).
