Description of the genus
Rhizome creeping or erect, often massive. Fronds tufted, closely spaced; pinnate (in young fronds), but 2-pinnatifid to 3-pinnate in more mature fronds, pubescent to hirsute, at least on the under surface; veins anastomosing freely. Sori discrete, not continuous, confined to lobe sinuses, marginal with membranous indusia.
Derivation of name: Blotiella: named after Madame M.L. Tardieu-Blot(1902-1998), a pteridologistof the Natural History Museum in Paris
Comment: To be able to distinguish the 2 species with absolute certainty, one needs to examen the rhizome!
Although only 2 species are known from our area, resent research in east Africa has led to the description of additional species. As far as we know such research has not yet been done in our area. It is therefore possible that additional species could occur in our region. (Pers. comm. C. Jongkind, 04-2012)
Worldwide: c. 12 species from tropical America, Africa to the Mascarenes
