Ic. Fil. t. 101.—Brown unites Todea with Osmunda, and makes the following observation.
“ Qnoniam in Todea, Willd., capsulæ vere pedicellatæ et cum porro alia species
existit iisdem pariter dorsalibus, at fronde pellucida Trickomanis instar donata, consultius
duxi ambas ad Osmundam emandare.” Prodr. p . 163.
