Gleisostoma taiwaniana HAYATA n. n. (Fig. 51). Sarcanthus taiwania- 



nus HAYATA in Mater. 

 EL Formos. p. 337. 



Owing to an erro- 

 neous observation, it 

 was first recorded that 

 this orchid lias a spur 

 divided by a longitudi- 

 nal plate and consequ- 

 ently was regarded as a 

 species belonging to 

 Sarcanthus. Afterwards, 

 I became aware of that 

 this has no plate but 

 thickenings. It should, 

 therefore, be transferred 

 from Sarcanthus to Sac- 

 cddbium.
