Since Franchet and Savatier cited the plate of Somoku 

 Dzusetu under Platanthera chlorantha in Enumeratio Plantarum 

 Japonicarum (vol. ii. 687), we have long applied this name to 

 our orchid. Though our plant has two large leaves at the base 

 of the scape, it is quite different from P. chlorantha or P. bifolia. 

 Our plant is rather closely allied to the North American P. 

 Hookeri, from which it differs by having a horizontally creeping 

 rootstock, foliolated scape, bracts shorter than the ovary, 

 smaller flowers, spur nearly twice as long as the ovary, etc.
