vel obovoideus brevissime restrains vel apiculatus 1-spermus 5-5| mm. 

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



HAB. Formosa (cult, in horto Koishikawensi). 



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

 brought back with an example of the type by Mr. T. UCHIYAMA 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.
