At oiir T a b . LXXIX. A., while I have figured only that group of Olfersia, which has
pinnate fronds, and the sori clothing hoth sides of the fertile pinnæ, I have at the same
time given Presl’s eharacter, which includes Elaphoglossum, Schott. This Mr J . Smith
again separates from Olfersia, with the character above given. It embraces most of the
old Genus Acrostichum with simple entire fronds.

The several species of this group, or Genus, as Mr J . Smith deems it, have heen
referred sometimes to Acrostichum, and sometimes to Lomaría, according as the margin
has been considered an indusium or not. It certainly is not a true indusium, and therefore
belongs to the Acrostichum family, whatever may be considered to he its claims to form a
peculiar Genus. Presl includes it in his Olfersia. Mr Smith justly observes that at fig. 4.
our representation of the anastomosing of the veins is not correct: there is, indeed, a
thickening of the substance transversely, where the veins terminate at the broad margin -,
and that, at first sight, gives the appearance of the veins uniting transversely.
