Tectaria coadunata

Taxonomy

In the North of India Clarke distinguished two varieties, one with large fronds glabrous on the lower surfaces and one somewhat smaller with fronds hairy beneath. He wrongly called the latter var. coadunatum', it is variable and has not been clearly distinguished. In northern Thailand, on limestone, there is a more densely hairy form which may represent a distinct variety.
