 According to S. Sasaki, collector for the Formosan Government, this 



plant usually grows on dry highlands from 2500-3000 m. above sea-level 

 but sometimes as low as 2000 m. altitude, but on Mt. Daibusan of South 

 Formosa it grows in the woods at about 1000 m. above sea-level. Its 

 trunk attains a height of 10-12 m. and a diameter of about 35-38 cm. 

 The bark is grayish white and has longitudinal cleavages ; the pith is large. 

 The manner of branching somewhat resembles that of Firmiana simplex 

 W. F. Wight; the leaves are evergreen.

1 Agalma DC. is cited erroneously by Steudel (Nomencl. ed. 2, 33 (1841] ) as a generic 

 name, though De Candolle (Prodr. vn. 250 |1838] ) had proposed it as a sectional name of 

 Mulgedium.
