numerous, usually deeply colored. Skin much deeper pink than that of the Early 

 Rose. Sprouts short, stubby, and showing about as much color as those in section 2. 



The varieties now thought to belong to section 3 follow. 



Crine's Lightning. 

 Extra Early Red Rose. 

 Jones Pink-Eyed Seedling. 

 Lee's Favorite.

5— EARLY OHIO GROUP. 



New Ideal (PI. VIII). 

 New Scotch Rose. 

 Old Early Rose (PI. VIII). 

 Seneca Beauty. 



This group is relatively more important than that of the Rose, 

 OAving to the fact that the Early Ohio variety is much more exten- 

 sively grown. In the potato-growing regions of the Middle West 

 the Early Ohio is still one of the leading commercial varieties. This 

 is particularly true in the Red River Valley of Minnesota and North 

 Dakota and in the valley of the Kansas (Kaw) River; it is equally 

 true in other less well-known localities. While in many respects the 

 varieties in this group are very similar to those of the Rose group, 

 there are certain distinguishing characters which make their recog- 

 nition comparatively easy. Plate IX, figure 2, and Plate X show 

 different views of the Early Ohio. 



Description. — Vines very similar to those of the Early Rose in habit of growth, 

 character of foliage, and color of flowers; they mature a little earlier, however. Flowers 

 white. Tubers round-oblong with full, rounded seed and stem ends (PI. X). Eyes 

 numerous, rather shallow, but strong, sometimes protuberant. Skin or flesh light 

 pink, except in the case of the White Ohio, with deeper color around the eyes, par- 

 ticularly around the bud-eye cluster. Surface of skin more or less numerously dotted 

 with small corky dots (lenticels). (PI. X, tuber 157.) These dots either do not occur 

 at all or are relatively inconspicuous on the Rose varieties. Sprouts short, much 

 enlarged at the base (PI. IX, fig. 2), color varying from carmine-violet to violet-lilac 

 or magenta-lilac. 



Apparently most of the varietal members of this group are simply 

 renamed Early Ohios; at least this statement is true of the first four 

 varieties in the following list : 



Early Ohio (PI. X). 



Early Market. 



Prize Early Dakota (PI. X). 



Ratekin's Red River Special. 



Early Acme. 

 Early Six Weeka, 

 Late Ohio. 

 White Ohio. 



6.— HEBRON GROUP. 



The varieties in the Hebron group are chiefly distinguished 

 from those in the Rose group by the color of their tubers. Most 

 of them are early-maturing varieties. The Early and Late Beauties 

 of Hebron were rather extensively grown a quarter of a century or 

 more ago, but are now seldom grown commercially. Their decadence 

 has been largely due to the fact that they are very susceptible to the 

 late-bhght. Another factor which may have had some influence in 

 this direction is the shape of the tuber, which is undesirably long.
