he same locality. Tt will be seen on comparing his descriptions 
It would seem probable that Mitten, having failed to find male 
flowers on Weir's plant, concluded that it was probably dioicous, 
and therefore not to be identified with Hampe’s species. 
The synonymy must stand as follows :-—

From time to time the value of this variety has been called in 
question; see Journ. Bot. 1904, p. 308, where Mr. Horwood quoting 
Mr. Riddelsdell (Bot. Exch. Club, 1900, p. 626) says it “ seems to

the presence of a leaf character of denudaia did not produce the 
unhealthy state described by Mr. Riddelsdell, but I think that
