lunulato-falcatis decurvis obtusis membranaceis approx-

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 pinne 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 go almost a black colour ;—L. trapezi- 
Jormis, retains its bright green in the Herbarium.
