440 ART. I. — B. HAYATA : 



it published. While working here at Kew, I have examined the 

 plant and found that it comes very near to A. resectum, from 

 which it can not be regarded as specifically different. I have, 

 therefore, tliought it better to describe it myself, as representing 

 a variety of the same species.
