A very singular plant, with the habit of an Aralioid and 

 especially of some species of Heptapleurum, which induced 

 Mr. Bentham (who had seen no specimens) when describing 

 the Magnoliacex for the " Genera Plantarum " to suggest 

 its belonging to that family. It had, however, been rightly 

 placed in Macjnoliacese by Siebold and Zuecarini, though 

 it does not belong to the tribe Winteracese to which these 

 authors had referred it. As determined by Eichler, it forms 

 along with the Japanese and Himalayan genus Euptelea, a 

 distinct tribe of Magnoliacese, the Trochodendrese, distin- 

 guished conspicuously by the absence of sepals and petals, 

 and which ranks with some authors as a separate Order. 



T. aralioides is a native of moist alpine woods in the 

 Islands of Yeso and Nippon, where it is found with species 



September 1st, 1894.
