Suborder V. MARATTIACEZ. 
Four genera are referred to this Suborder ; those not found within our limits being 
the curious Asiatic monotypic Kaulfussia and the genus Angiopteris, which ranges 
from India to Madagascar, Australia, New Caledonia, and the Society Islands. Hooker 
and Baker regard all the forms of Angiopteris as varieties of one species, while De 
Vriese describes sixty of them as species.
