 in rupibus declivitatis alpini Kanboho 2300 m. ubi socialiter crescit 

 (Takenoshin Nakai n. 6954). 



This plant grows in the alpine grass-region where Betula Ermani, 

 Alnus Maximowiczii and Larix Principis-Ruprechtii end at their upper 

 extremities. There are no big and stout herbs, so this is in fact a 

 monster among the alpine plants. The affinity of this is of course 

 Rheum tanguticum. Without inflorescence it would be difficult to dis- 

 tinguish this from that.
