Ranunculus Linn. 



Ranunculus cheirophyllus Hayata n. n. 



Eanunctdus Kawalcamii Hayata Mater. FJ. Formos. p. 19 ; Ic. PI. For- 

 mos. I. p. 27, t. 6, (non Making). 



As the name R. Kaioalcamii had abeady been given to a Japanese 

 plant, it is much desirable to give to the Formosan plant another new 

 name, R. cheirophylhis.
