' Adiantum lunulatum appears to have a very extended geographical range, being found both upon 

 the continent* and the islands of India, as well as in Mexico. 



The editor of the Reliquice Hamkeance, on the authority of specimens in Willdenow's herbarium, 

 has referred the A. arcuatum of that author and Swartz (the A. lunatum of Cavanilles) to our plant, 

 as a very trifling variety with the lobes of the pinnae more deeply cut than usual. 



* As far north as Nepaul, where the specimen here figured was gathered by Dr.Wallich.
