PURPLE-FLOWERING RASPBERRY 



ceptacle with the calyx is stronger than its union 

 with the drupes; so when the so-called berry is ripe 

 the aggregation of little drupes slips off the recep- 

 tacle and leaves it behind grown fast to the calyx. In 

 the blackberry the conditions are reversed ; the union 

 of the receptacle with the drupes is stronger than with 

 the calyx, so when the berry is ripe the drupes carry 

 the receptacle with them. This is the explanation of 

 the white core always found at the centre of a black- 

 be rry. 



PURPLE-FLOWERING RASPBERRY 



Rubus odoratus. 



Raspberry, from the Italian raspo, rough, on account of 

 the roughness of the stem and leaves. 



A straggling shrub with upright stems, three to five feet high, 

 found by roadsides, in mountain paths and moist, shady places. 

 Spreads rapidly by underground stems. Ranges from Nova 

 Scotia to Ontario and Michigan, south to Georgia and Ten- 

 nessee. 



Bark.— On old stems pale, dull yellow, becoming loose and 

 stringy. The recent shoots and flower branches are thickly 

 covered with purplish glandular hairs, which continue up the 

 petiole, along the midrib and primary veins on the under sur- 

 face of the leaf, and thickly invest the flower-stalk and the 

 calyx. 



Leaves. — Alternate, simple, large, seven to nine, sometimes 

 twelve inches broad, palmately three to five-lobed, cordate at 

 base. Lobes serrate, acuminate ; the middle one longer than 

 the others. They come out of the bud plicate; shining, red- 

 dish, glandular-pubescent ; when full grown are bright green, 

 rough, hairy above and beneath. They remain unchanged until 

 destroyed by the frost and storms. Petiole long, very pubescent, 

 enlarged at base ; stipules small, lanceolate, acuminate.
