. The book of choice ferns for the garden, conservatory. and stove : describing and giving explicit cultural directions for the best and most striking ferns and selaginellas in cultivation. Illustrated with coloured plates amd numerous wood engravings. Identification; Ferns. CHAPTER XI, DAYALLIA, Smith. (Dav-ar-li-a.) Hare's-Foot HIS large genus derives its name from Edmund Davall, a Swiss botanist, to whom it was dedicated by Smith ; it is almost entirely composed of Ferns having their headquarters in the Tropics of the Old World. According to Hooker and Baker's " Synopsis Fihcum," Tribe 4, the DavaUiea^, is composed exclusively of the genus Cystojjteris, already described, and of Davallia. In the above-named work Davallia forms Genus 18, and we find side by side in this genus plants with fronds varying in size and division, and also in texture, being sometimes herbaceous (soft and papery), and at other times coriaceous (of a leathery nature). The mode of fructification in Davallia is so thoroughly distinct that there is very little difiiculty in identifying the species when once their most distinctive characters are understood. In all Davallias the sori (spore masses) are either marginal or sub-marginal (disposed quite upon or close to the outer edge of the fronds) ; they are generally globose or roundish, but sometimes elongated, either laterally or vertically. They are disposed in shortly- but distinctly-stalked capsules, and are covered by involucres that are variable in form, being sometimes reniform (kidney-shaped), sometimes nearly round, always open at the summit, broadly fastened at the base, and generally united, though occasionally open at the sides. The veins are always free, and although there are a few exceptions, the majority of the species produce their.
