Very near Jlercurialis leiocarpa Sieb. et Zucc, but differs from it iu 

 having the less verrucose ovary with the much siireading stigmata and the less 

 verrucose or nearly smooth capsules. The distinctiou of this i)lant fi-om M. leio- 

 carpa is even more clear in the living specimens. The leaves of the new 

 species are jiale green and of ordiuary laster, while those of the Japanese are 

 deep green, shining and almost opalescent. The former has the ovate lanceolate 

 leaves which are usually obtase at the basc, while the latter has the ovate 

 obloiig oues which are iLsuallv rounded at the base.
