Sj^ec. Chnr.y S^c. Leaves oval-ovate and with a 

 long aciiniipiiite tip, toothed, pubescent with 

 hairs beneath. Flowers sohtary, 2 or 3 together. 

 Lobes of the calyx very long, acuminate. Style 

 4-clett. Stigmas about level with the stamens. 

 (Dec. Prod.) A low straggling shrub. North 

 America. Height 4 ft. to 5 tt., but covering 

 double that space upon the ground with its long 

 slender deep brown shoots. Introduced about 

 1830. Flowers white, most commonly solitary 

 and almost scentless. ; 



The leaves are smaller than is usual in the genus, 

 very sharp-pointed, with the toothing unusually 

 shar[) ; the uppermost leaves become gradiially 

 narrov/, till those immediately below the flowers 

 are not unfrequently linear and entire. As this 

 species leafs early, the young shoots are apt to be 



killed h\ frost, and when this takes place no flowers are produced that season, 

 as it is from the ends of the lateral shoots that blossoms always appear in this 

 genus. (Bot. Reg.)

 1811. Flowers white ; June and July. 



We have given this description and figure from 

 Schrader and Guimpel, because in 1837 there was a 

 plant in the Hort. Soc. Garden which answered to 

 it, and which differs from P. speciosus in the leaves being nearly entire.
