This species only differs from L. vespertUionis Lahill, {L. incisa, Thunb) by tbe anastomosing of the veins being always
constant. Sir W. Hooker keeps them distinct, but Dr. Hooker imites the two iu his “ Floræ Novæ Zelandiæ.”

Sori oblong or sub-Iunulate, in one or more series, arranged transversely with the veins forming areoles which are superficial,
