The forms of the leaves in Matsumura's specimeus are ellip- 

 tical or kinceohxte-elliptical, with long acuminate mucronate 

 apex, while in Ito's specimens the}^ are oval or obovate-oval, 

 with obtusely cuspidate or acuminate apex. As our materials are 

 iiot sufficient to determine the limitatioii of species in this dif- 

 iicult genus, Ave have simply followed Maximowicz. Lawson (in 

 Hook. f. Fl. Brit. Ind. I, p. 039) unites many forms under tlie 

 name 11. dahurlca, while Forbes et Hemsley left Wright's 

 specimens from the Luchuan Islands undermined. Further 

 investigalion is necessary to defme the limits of tlie Easteru 

 Asiatic species of this genus.
