Hab. Cuba and Mexico to Brazil and Ecuador.—We take our description here frorn a
plant grown at Kew, with which Liebman’s specimens and the description of Mettenius
quite correspond. In the typical plant the pinnæ are not more than pinnatifid, but in
Grisebach’s striatum ¡3 and Liebman’s D. amplum, the lower segments are distinctly
separated, 1 4 * 2 in. 1., ^ in. br., aud broadly inciso-crenate, and the lower sori 2 lin. 1,
The W. Indian D. grammitoides, Fée, resembles this in habit, but the involucre is thin
and very evanescent.

plant from Borneo has a very fibrillose rachis, and the lobes of the lower pinnæ quite
distinct, 1 | in. 1., in. br.

Hab. West Indies southward to Peru.—This differs from all the preceding by its very
large pinnæ and lobes. The extremes of the two forms look very different, but are
connected by intermediate stages. D. apollinaris and Tussaci, Fée, are allied.
