Small herbaceous perennial with creeping rootstock and erect flowering stems, 

 10-20 cm high with about 2-5 leaves or more, slightly pubescent or glabrous. Petioles 

 longer than the blade, slender; stipules ovoid, obtuse or pointed; leaves simple, cordate or 

 reniform at the base, broader than long, the lower ones almost entire, the others deeply 

 3-lobed, the lobes obtuse or roundish, doubly crenate or serrate, glabrate at length, 3-6 cm 

 wide. Flowers solitar>-, terminal, peduncles overtopping the leaves, often with 6-8 sepals 

 and petals. Calyx finely puberulous, lobes narrowly lanceolate, acuminate; petals obovate 

 or oblanceolate, long clawed, rose colored, exceeding the calyx -lobes; stamens numerous 

 with dilated filaments. Fruit globose with 20-25 drupelets, glabrous; putamen smooth; 

 calyx reflexed on the fruit.

Arctic Raspberry.— Herbaceous perennial, with a slender creeping rootstock. Stems 

 S-20 cm high, finely pubescent, 2- to 6-leaved; stipules large, obovate, rounded; petioles 

 2-4 cm long, finely pubescent; leaflets 3, simply or doubly toothed, lateral ones sessile, 

 broadly obovate-rounded, on the upper leaves more acute, terminal ones short stalked, more 

 or less acute, especially the upper ones. Flowers 1-3, polygamo-dioecious, 5- to lo-parted; 

 sepals lanceolate, acute, finely pubescent; petals obovate, entire or emarginate, 7-10 mm 

 long, rose-red. Fruit globose, dark red, fragrant, edible. 



Northern Europe, Asia, and North America; from Labrador to the 

 Canadian Rocky Mountains in the New World. The fruit is smaller than 

 that of R. chamaemorus; when full grown and ripe it is not unlike that of 

 the raspberry.
