R. idaeus var. aculeatissimus. Robinson & Femald in Gray New Man. 7th Ed. 486. 

 1908. 



Canes erect, arching at the top, reddish or brownish, sometimes with a whitish bloom, 

 glabrous and more or less densely beset with fine bristles. Leaves of the canes 3- but mcstly 

 5-foliolate, rather thin, more or less glabrous above, white tomentose below; stipules 

 small, setaceous; petioles, petiolules and midveins glabrous but finely bristly and glandular; 

 lateral leaflets sessile, obliquely ovate, pointed, doubly serrate, the teeth ovate, mucronate ; 

 the lowest pair larger, often sublobed; terminal leaflet cordate-ovate, shortly acuminate 

 or more or less 3-lobed, about 8 cm long. Flowering branches glabrous, but prickly and 

 glandular, often glaucous. Leaves 3-foliolate, narrower and more pointed, uppermost 

 simple lanceolate. Flowers racemose, drooping; pedicels and calyx and calyx-lobes not 

 tomentose, distinctly glandular, bristly and prickly. Fruit hemispherical, light red. 



Eastern Asia and North America; from southern British Columbia 

 to southern Newfoundland, south to Oregon, Wyoming, the Great Lakes 

 and Mrginia. It varies a good deal but is always easily distinguished by 

 its more slender habit, the canes are less erect, the leaves narrower and 

 thinner than in R. idaeus vulgatus. From this variety the American culti- 

 vated red raspberries are derived.
