R igidum—Bigid.
A FINE tropical Fern , from Jamaica, Dominica, Martinique,
Brazil, P e rn , Quito, Mauritius, Islands in the Pacific, Philippine
Islands, and Ceylon.
The fronds, which are broadly ovate, thick, and rigid, are
bipinnate; the^ pinnules lengthy lanceolate, cuneate; ultimate
segments varying in size, subacute, and either simple or bifid,
very narrow and rounded.
Involucres supra-axillary on the inner margin of tbe lower
segments, free, the mouth entire, and not two-lipped.
Eacbis terete, wingless, or witb a narrow wing.
Fronds nine to twelve inches in length; the stipes from four
to six inches, sometimes more, being h a lf the length of the
whole frond. Colour dark green.
Sori numerous.
Fronds erect, on round wiry stalks.
Requires a very humid b u t airy atmosphere, with a temperature
varying between 55° and 80°.
There is a variety with broader and more crowded divisions.
The typical form has nearly flat and somewhat dense fronds.
My thanks are due to Messrs. J . Backhouse and Son, of
York, for tbe frond illustrated.
