I n concluding the A d ia n tum s it Avill be necessary to offer
a few words reg a rd in g two or th re e species that have not
been figured, and in doing so it seems desirable to give a
list of the A d ia n tum s described by Sir. AV. J . H o o k e r, in his
“ Species Filicum,” although many of them have never been
b ro u g h t to E n g la n d in a living state. These F e rn s are h e re with
given with the numbers they bear in Sir M^. J . H o o k e r’s
work. Those marked th u s * are figured in the p re sen t volume,
and consequently cultivated in this country.
