AMERICAN POTATOES: CLASSIFICATION AND DESCRIPTIONS. 7 
The varieties in this group which have been studied are the Early 
Albino, Early Michigan (Pl. V), and Early Puritan. 
Further investigation will doubtless result in the inclusion of a 
number of other varieties. 
4.—ROSE GROUP. 
In point of numbers the Rose group is one of the largest, if not 
the largest, group under this classification. With the exception of 
the Extra-Early White Rose, all of the varieties in this group have 
pink-skinned tubers, and all save the Late Rose may be classed as 
early-maturing varieties. 
In order to accommodate certain varieties which apparently belong 
to this group, but which differ either in shape of tubers, color of 
sprouts, or flowers, it has been found necessary to make three sec- 
tions, in the first of which are included the true Early Rose types. 
The vine description of the Early Rose in section 1 will serve reason- 
ably well for all. Plates VI, VII, and VIII illustrate the different 
varieties belonging, respectively, to sections 1, 2, and 3. 
Description.—Section 1: Vines of medium height, with stout, rather erect, dark- 
green stems and medium to large leaves. Flowers rather abundant, white. Tubers 
elongated or oblong, usually flattish at the center and tapering gradually toward 
each end; stem and seed end rather blunt. In the North, tubers tend to become 
shorter, thicker, and more nearly round. (Pl. VI, figs. 1 and 2.) Eyes numerous, 
shallow to medium in depth, but sharply marked; sometimes protuberant. Skin 
smooth and, except in the Extra-Early White Rose, of a rather deeper shade of flesh 
color or pink than the Early Ohio. Flesh creamy white, sometimes streaked with red. 
Sprouts rather long, medium thick, the base not much enlarged (PI. IX, fig. 1) and 
usually clearly tinted with rose-lilac; leaf scales and tipscreamy white or tinged with 
rose-lilac. 
The following varieties are thought to belong to section 1: 
Clark’s No. 1. Extra-Early Fillbasket. 
Early Durham. Extra-Early Vermont. 
Early Fortune. Extra-Early White Rose. 
Early Maine. Houlton Rose. 
Early Norther. Late Rose. 
Early Rose (Pl. VI). Northern Beauty. 
Early Roser. Rochester Rose. 
Bee Thoroughbred. Somers’ Extra Early. 
arly Vermont. chonbitrn: 
Early Walters. 
Section 2: Vines larger and more luxuriant than those of section 1. Flowers white. 
Tubers broad-roundish to short-oblong, flattened (Pl. VII). Eyes not very numerous 
and rather shallow. Skin slightly deeper colored than that of the Early Rose. 
Sprouts shorter and thicker and usually considerably enlarged at the base; color 
of sprouts mauve; leaf scales and tips deep mauve or magenta. 
The varieties classed under section 2 are the Manistee (Karly and 
Improved) and Spaulding No. 4 (Pl. VII). 
Section 3: Vines quite similar to those of section 1. Flowers purple or rose-lilac. 
Tubers oblong, rather broad and thick, more or less flattened, large (Pl. VIII). Eyes
