AMERICAN POTATOES: CLASSIFICATION AND DESCRIPTIONS. g 
B scriiion: —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 | 
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 m 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 (Pls. 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 omen 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). Inall 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. 
Section 1: Section 2:
