4 Diplazium polypodioides. (Metten). Caudex erect, often a trunk, stipes and rachis more or less prickly and scaly, fronds
very large, coriaceo-membranaceous, bi-pinnate -with tbe pinnules mote or less deeply pinnatifid, often nearly down to the rachis, primary
)iunæ (at least the lower ones) petiolate, ovato-lanceolate, acuminate 8 inches to nearly 2 feet long, pinnules sessile or sub-sessile, 3-5
inches Ion»-, J to 1 inch broad, oblong broader a t the base and gradually attenuate to the acuminated apex, segments oblong-parallelogram,
or slightly falcate obtuse, crenated or serrated ; veins simple or forked, extending to the margin, sori one to each vein, on each side of
the costa touching tbe costa, but not extending to th e margin, generally only one of the lowest ones double.— Afriten. Fil. Hort. Lips. p.

Sori indusiate linear, all or the lowest only double, i.e., th e receptacles occupying both sides of the veins. Indusium narrow
membranaceous plane or fornicate, in the double sori affixed in pairs back to back on opposite sides of the same venule, one opening,
anteriorly, the other posteriorly ; in the simple sori as in Asplenium. Veins forked or pinnate from a central costa ; venules anastomosing
irregularly at an acnte angle, or each opposite pair uniting between the primary veins in superposed acute sub-triangular areoles, the
marginal or superior vdnlets free.
Fronds herbaceous or coriaceous, pinnatifid, pinnate, or bi-tri-pinnate, sometimes proliferous. Rhizome short, erect. Large
growing ferns only distinguished from Diplazium by the conniveutly anastomosing veins which are analagous to those of Nephrodium
(in Aspidiece) and Goniopteris (in Polypodieæ.) (Moore.)
1. CallipUris esculenta. (Houlst. et Moore). Caudex stout, erect, very scaly a t the summit, stipites tufted, stramineous-brown,
angled ; fronds ample broad, oblong acuminate bi-pinnate, below pinnatifid, in the middle simply pinnate, terminal pinnæ large, pmnatifid
at the base, primary lateral pinnæ l | - 2 feet long, petiolate horizontal oblong acuminate, pinnules distant horizontal sessile, or shortly
petiolate from a broad truncate frequently hastate base oblong gradually acuminated 4-6 inches long, varying in breadth entire or serrated,
or variously and regularly lobed or pinnatifid a t tbe margin, most so a t the base, the lobes obtuse, serrrated, veins very patent, fasciculate
pinnate, tbe branches uniting with those of the opposite fascicle, sori copious on the veinlets rather short, linear decussate often diplazioid,
aud at length confluent, mvolucres narrow, brown membranous, costæ beneath often squamuloso-furfuraceous. Hook. Sp, Fil. iii. 2C8.-—
