A well-marked specicvs characterized by its leaves, tlie l-3-flo\vercd in- 

 florescence and by the large fruit. It appears related to S. lucida Sieb. & 

 Zucc. which has smaller serrate leaves, shorter petioles, fascicled flowers 

 and smaller fruit. This new species is common on Muko-jima, but Wilson 

 did not see it elsewhere. Tlie Chichi-jinui specimen from the herbarium of 

 Mr. Otonio looks quite different at first sight witli its slenderer branchlcts, 

 smaller obovate to oblong-obovate leaves, but on critical examination we 

 are satisfied that it belongs to the same species and is from a weak branch.
