Danaea kalevalaMaarten Christenhusz
Danaea kalevala Christenh. was recently described to separate it from D. nodosa (L.) Sm. which has a very different rhizome and habit. There are also genetic differences between the species (Christenhusz et al, 2008). Danaea kalevala occurs in the Lesser Antilles, and is quite rare except on the southern slopes of La Souffrière, Guadeloupe, where it still is reasonably common.
The species is characterized by an enormous dorsiventral rhizome, with multiple rows of fronds, stipes without nodes and tall fronds, with many lanceolate pinnae. The pinna apices are finely serrulate to almost entire.
The epithet honours the heroic epic of Finland.
