Recent teratological literature,— De Candolle^^ presents a 



second contribution to our knowledge of the ascidia of Ficus, basing his 

 observations on living material from the Botanical Gardens at Calcutta, 

 where there are two young trees grown from cuttings from an older tree 

 in the vicinity of Calcutta. The leaves of these trees he designates as 

 hypoascidia, the inner surface of the ascidium representing the ventral 

 surface of the leaf, as contrasted with epiascidia, the usual form in which 

 the inner surface is homologous with the dorsal surface of the leaf.
