AMERICAN POTATOES: CLASSIFICATION AND DESCRIPTIONS. Il1 
freely and develop reasonably large plants. Tuber formation seems 
also to be delayed, but when the proper growing conditions prevail 
"in the latter part of the season a crop is developed very rapidly. As 
_a group, the tubers are of desirable shape, attractive color, and good 
table quality, and the vines are fairly resistant to drought and to 
diseases other than the late-blight. 
In order to include russet-skinned varieties possessing characters 
practically identical in all other respects with those of the white- 
skinned class, it has been thought desirable, as in the case of the 
Burbank group, ‘to make two sections. Inasmuch as the vine and 
tuber characteristics, save for the color of the skin, are alike for. 
the two sections, one description serves equally well for both. 
Description.—Vines medium large. Primary stem upright, long jointed, and 
rather sparsely covered with foliage; lateral branches more or less decumbent, giving 
the plant a straggly appearance. Stems more or less distinctly streaked with dark 
purple. Leaves rather small, dark green, more or less rugose or crumpled, and leath- 
ery to the touch. Flowers medium, abundant, and of fair size; the central portion of 
the corolla isa deep violet-purple, which gradually shades into a lighter tone toward the 
periphery. The color is practically absent on the upper side of the five points of the 
corolla. Tubers round-flattened to broadly roundish oblong-flattened or distinctly 
oblong (Pl. XVI.). Eyes few, very shallow, bud-eye cluster strong and frequently 
depressed. Skin creamy white and occasionally netted in the varieties of section 1, 
while in those varieties belonging to section 2it isa deep-russet colorand much netted. 
Sprouts short, base enlarged, dull white; leaf scales and tips medium to deep purple 
or pansy violet. 
The varieties which have been recognized as belonging to section 
1 of this group appear in many cases to be old ones under new names; 
as, for example, Late Vicktor, Lily White, No.9, Noxall, Ohio Wonder, 
Prosperity, Rhind’s Hybrid, and White Giant. These varieties are 
all considered to be practically identical with the Rural New Yorker 
No. 2. 
The following varieties are classified under sections 1 and 2: 
Section 1: Section 1—Continued. 
Arcadia. Prosperity. 
Carman No. 3 (Pl. XVI, fig. 2). Rhind’s Hybrid. 
Great Divide. Rural New Yorker No. 2 (Pl. 
Jackson White. xeV To fies 1). 
Late Vicktor. Sir Walter Raleigh. 
Lily White. White Giant. 
Million Dollar White Swan. 
Noxall. Section 2: 
Noo. Late Petoskey (Rural Russet). 
Ohio Wonder. Russet (Dibble’s). 
Peerless (Bresee’s No.6) or Boston. 
10.—PEARL GROUP. 
So far as the writer’s studies are concerned, only three varieties can 
be assigned to the Pearl group. These are the Pcarl, the People’s, 
and the Blue Victor. In Colorado, Idaho, and adjoining States
