 be a very interesting one. In the imperfectness of the specimen, 

 the specifical determination is impossible.

DiSTRiB. In Japan ; very common in the valleys of the lowland 

 hills. The distribution of the genus Mitella is rather limited, being 

 found only in North America, Manchuria, East Siberia, Japan and 

 Formosa. 



The Morrison specimens are of a form having rather more 

 divaricate and fi^ibriate petals and less tuberculate seeds. A more 

 diverged form of this species was found in Japan by Mr. T. Making 

 who described it in Tokyo Bot. Mag. XIX. p. 17 as a new variety 

 integripetala. Another species M. acerina Making was found also 

 in Japan.
