AMERICAN" potatoes: CLASSIFICATIOIT AND DESCEIPTIOlSrS. 9 



Descri-ption. — Varieties of this group mature medium early, except in the case of 

 the Late Beauty of Hebron. Vines very similar to those of the Early Rose. Flowers 

 white. Tubers elongated, somewhat flattened, with rather blunt ends, occasionally 

 spindle shaped (PI. XI). Eyes numerous, medium deep. Skin creamy white, more 

 or less clouded with flesh color or light pink. Sprouts very similar to those in section 1 

 of the Early Rose group, but with rather less color.

7.— BURBANK GROUP. 



While the Burbank group is relatively small, it is by no means un- 

 important. The potatoes in this group are very much more widely 

 grown in the West than in the East, their production being probably 

 most concentrated on the delta lands of the Sacramento and San 

 Joaquin Rivers, near Stockton, Cal. The varieties constituting this 

 group all produce long, cylindrical, white or russet tubers. It has not 

 been thought advisable to attempt to make two groups, one white 

 and one russet, because in all other respects the potatoes appear to 

 be very similar. To accommodate these two classes of tubers the 

 group has been divided into two sections, section 1 including the 

 white-skinned types and section 2 the russet-skinned ones. 



Description. — Vines bushy and medium large. Stems light to medium green, 

 branched, and spreading. Leaves abundant and medium in size, medium green in 

 color. Flowers white. 



Section 1: Tubers long, cylindrical, or slightly flattened in shape (Pis. XII and 

 XIII), inclined to be prongy when climatic conditions are abnormal. Eyes numerous 

 and well distributed, rather shallow, occasionally protuberant. Skin white to dull 

 white, smooth to glistening. Sprouts, base creamy white or faintly tinged with 

 magenta, leaf scales and tips usually lightly tinged with magenta. 



Section 2; Tubers have russet skin, heavily netted or reticulated (PL XIII, tuber 

 558). In all other respects these are very similar to those of section 1, except possibly 

 that the tubers of Cambridge Russet and Scabproof are slightly more flattened. 



The varieties listed below seem to belong to this group.
