A plant of the small tree-fern Todea Wilkesiana (Fiji, Samoa, and other islands) in the filmy- fern house at Kew, to which my attention was drawn by my friend Mr A. W. Hill, has a slender stem with the characteristic leaf-scars exposed; it presents a striking similarity to some of the fossil species of Osmundaceae described in a later chapter. Schizaeaceae.
