Hab. Adam’s Peak, Ceylon, Mrs. Genl. Walker . 
Nearly allied to L. trapeziformis , Dryander, which species 
is found in the East as well as the West Indies: but the 
present plant has more numerous pinna? on the frond, tapering 
to a tail-like point, blunted pinnules, exactly marginal sori; 
terete and darker coloured stipes ; — and these marks are found 
in four fine specimens received from Ceylon at different 
periods. This dries to almost a black colour; — L. trapezi- 
formis , retains its bright green in the Herbarium.
