and 0.25 m. in diam. and with a spreading round head about 7 m. in 

 diameter. There is no doubt that the other parent of the hybrid is P. 

 americana Marsh, which was standing near the parent tree, as it is clearly 

 intermediate between the two. From P. americana it differs chiefly in 

 its lower more shrubby habit, in its pubescent branchlets, in its somewhat 

 broader more finely serrate leaves, more or less pubescent beneath, in 

 the shorter pubescent petioles, in the smaller purple fruit and smaller 

 stone. From P. maritima Wangh. it may be distinguished by the branch- 

 lets being glabrous at maturity, by the larger acuminate more deeply 

 and sharply serrate leaves, glabrous or nearly so above, less densely 

 pubescent beneath, by the glabrescent pedicels and calyx-tube, longer 

 sepals, larger purple fruit and larger more compressed stone. From P. 

 lanata Mack. & Bush with which it may be confused on account of the 

 pubescent leaves it can be distinguished by the more finely serrate leaves, 

 shorter petioles, and shorter pedicels on the smaller purple fruit. 



The two trees of this hybrid differ considerably in their leaves; the 

 tree in Genesee Valley Park (No. 1154) has somewhat larger and broader 

 more or less ovate leaves rounded at the base, more rugose and with a 

 few scattered hairs above, hairy on the midrib, veins and veinlets beneath; 

 the tree in Highland Park has smaller leaves, often more or less obovate 

 in outline, 8 cm. long and 3.5 cm. wide, broadly cuneate at base, quite 

 glabrous above, beneath only densely hairy on the midrib, glabrous or 

 glabrescent on the veins and veinlets, and shorter petioles not exceeding 

 8 mm. in length. 



As an ornamental, this hybrid plant seems to surpass when in bloom 

 both parents in beauty, judging from the photograph of the tree in Genesee 

 Valley Park.
