 longus 4 mm. in diametro, pedicellis 5-6 mm. longis. 



Hab. Formosa (cult, in horto Koishikawensi). 



Differs from the type only in having much narrower leaves. It was 

 brought back with an esample of the type by Mr. T. Uohiyama from Formosa, 

 and has been cultivated for nearly fifteen years. Examples of the type 

 and the present variety are planted on a western slope of the Koishikawa 

 garden. It is suggested to me by Mr, T. Nakai .that this may be a new variety 

 of E. Oldhami Maxim.
