Western China: mountains, alt. 2800 m., May 1904 (Veitch Exped. 

 No. 3526). 



This plant, on account of the rather short and mostly simple serratures of the 

 leaves, does not fit very well into the series Ceraseidos, but it resembles P. Zappey- 

 ana so closely and the petals and stamens are, as usual in Ceraseidos, so small, that 

 I cannot place No. 3526 elsewhere.
