This is one of the plants of Henry's collecting from 

 the region of Mengtsz, and was referred by Hemsley and 

 Wilson^ to Rli. irroratum. Subsecpiently Rehder and 

 Wilson '-^ suggested that it might, with others of Henry's 

 collecting about Mengtsz, be a variety of A'A. (/ymnanthiiw. 

 (see under Rh. nwnfjtszense and RJi. s/>anotric/ium in this 

 paper). It certainly finds its place in the Irroratum series
