CLASSIFICATION. 67 



thin bloom ; the flesh soft and juiey, often stringy, closely ad- 

 herent to the small, broad, roiighish stone. Well represented 

 by Newman and Lone Star. 



The species has one comparatively unimportant sub-species, 

 P. angusUfolia var. Waisoni, Waugh, the Sand plum, a bushy 

 spiney plant with zigzag twigs. Not much cultivated. 



THE CHEEEIES. 



Flowers usually fasicled or umbellate, stalked, usually ap- 

 pearing ivith the leaves, the latter conduplicate in the bud; 

 fruit small and mostly globular, and nearly aliuays smooth and 

 destitute of bloom; the stons nearly or quite spherical and 

 . mostly smooth. 



The cultivated cherries belong to two species, each of which 

 a,re divided into several very distinct groups. The classification 

 of cherries is comparatively simple, the varieties falling readily 

 into the natural groups which for most part are readily recog- 

 nized by even the tyro. Of the several very good classificatory 

 outlines that of Bailey and Powell from Bulletin 98 of the Cor- 

 nell Experiment Station is most satisfactory and follows the 

 species next described. 



P. Avium, Linn. Ma-zzabd^ Sweet^ Heaet and Bigaeebatt 

 Cheeeies, GuiGJiTES OE Geaws. — Taller, with a more erect 

 growth, and reddish brown, more or less glossy bark; flowers 

 usually borne in dense clusters oil lateral spurs, and appearing 

 ^i^ath the hairy conduplicate young leaves, the persistent bud- 

 scales large; leaves mostly oblong-ovate and gradually taper- 

 pointed, dull and soft, hanging limp upon the young growths; 

 frait sweet (or sometimes sour, as in May Duke), yellow or red, 

 often pointed. Europe. Divided into four well marked groups 

 as follows:
