Observe the intimate attachment of the parasite to its prey, 

 best seen by making a section through the plane of union. 

 The wood of the parasite and that of the stock, although in 

 most intimate union, do not intermix or shade off into each 

 other. Observe, also, the corolla, deeply split on one side, 

 in some species quite regular : the inferior ovary, buried in 

 the disk which grows up around and adherent to it; the 

 single erect ovule which it contains is entirely adnate with 

 the walls of tlie one-celled ovar}', so that if the latter be cut 

 across at the time of flowering, it appears to be quite solid. 



Several species of Mistletoe {Viscw?i), both with and 

 without leaves, are common parasites in India. They differ 

 from Loranthus in their minute petals, and in the adnate 

 anthers, dehiscing by numerous microscopic pores.
