Hab. Australia, Van Diemen’s Land, and New Zealand.—“ Very closely allied to
D. media! ^nd probably a variety of it, but more flaccid, the fronds often prostrate,
pinnate nearly to the top, fertile more distinct from the barren and longer.”—
Dr. Hooker, Fl. N. Z. p. 370. A curious form (D. linearis, J . Smith) from New
Caledonia and Australia, has a long narrow linear frond, the upper part undivided, only
the lower third sinuato-pinnatifid, with short rounded lobes, the lowest of which are
distinct.
T r ib e 8. Asplenieæ.
Sori attached to the veins, oblique with regard to the costa or occasionally subparallel

Acropteris and Actiniopteris, and with Grammiti'deæ by Ceterach. T ab. IV.
