24 ADTANTUM LUNULATUM. 



William Hooker thinks that the Brazilian Fern, ( Adiantum 

 deflectens, of Martens,) may also prove to be another form of 

 A. lunidatum. 



A stove Fern, which is deciduous. 



A. lunidatum is a native of the East Indies, Malay Islands, 

 Africa, the Islands of Ceylon and Java, Mexico, the Cape de 

 Verde Islands, the Organ Mountains in Brazil, Acapulco, Quorra 

 near Attah, Panama, Minas-Geraea, etc. 



The form of the frond is oblong, pinnate, pinnae alternate, 

 lunate on lengthened petioles or foot-stalks, lobed on the su- 

 perior margin, blunt at the base. Fronds glabrous; the sterile 

 ones pendulous, and the fertile ones erect. Stipes and rachis 

 glabrous, ebeneous ; the rachis often extending beyond the 

 pinnae, rooting at the apex. 



Length of frond about a foot; colour brilliant green. Ter- 

 minal attached to a fasciculate rhizoma. 



Sori linear, approximate, frequently becoming confluent. 



I have been unable to procure a plant. To Sir "William 

 Hooker my thanks are due for fronds. 



It appears only to be included in the Fern Catalogue of 

 Messrs. Rollisson, of Tooting. 



Propagated by allowing the apex of the fronds to root into 

 the soil. 



The illustration is from a frond given to me by Sir William 

 Hooker.
