 1907 (No. 3; mixed with flowering and foliiferous twigs of P. Conra- 

 dinae Koehne). 



This species is in the leaves, fruits and particularly in the spots on the petioles 

 so characteristic, that it should not be left undescribed,

> I have seen only two pedicels with fruits, each wnth a larger and a smaller fruit. 

 It can, however, hardly be assumed that the species has always such twin-fruits.
