thin. It goes without further saying that the very large fruited 

 sorts are not soHcl nor with thick walls, while the kinds with the 

 equatorial axis exceeding the polar and neither long are quite 

 certain to have the wall thick — are, in other words, fleshy or 

 solid. 



In transection the pepper wall shows great diversity. In 

 those with a circular outline, the wall is quite uniform with the 

 placentae built upon it at two or more places and meeting at 

 the center in the basal core or extending into the body cavity of 

 the fruit above the core. In those fruits that soon become ru- 

 gose (wrinkled) sometimes seen in the bud, there is quite a dif- 

 ference in the thickness of the wall, the infolds being the thinner 

 parts, which in regular fruits alternate with the thicker ridges 

 and bear probably a definite relation to the placental lines. 



COLOR IN PEPPERS. 



The color in peppers is quite variable; beginning with the seeds, 

 they range from light to dark yellow, light to dark tan to red. 

 The seedlings show only slight differences in the green of the 

 cotyledons and first leaves ; possibly there may be ( i ) a light 

 and (2) a darker green line of separation of the varieties. 



Considering only the upper side of the mature leaves, they 

 vary, according to Prang's System, from green yellow green of 

 Chart V ( 5 GYG) to yellow yellow green of Chart IV (4 YYG) ; 

 in other words, the thirty-one commercial kinds examined were 

 grouped as follows : 11,(5 GYG) ; 2, ( e GYG) : 3. ( 5 YG) ; 12, 

 ( 4 YG) ; and 3, ( 4 YYG) . In other words, all ordinary pepper 

 foliage shows yellow and in some instances this is more empha- 

 sized than the g'reen. 



There is a group of varieties represented by the "Black Nu- 

 bian" that has much purple throughout the plant ; in its various 

 crosses, the shade of the green of the foliage falls into the first 

 group above. 



The stems of some kinds are entirely green while many show 

 traces af a purple color that l)ecomes quite pronounced at the 

 nodes. In some of the "Nubian" crosses this dark color is either 

 in narrow lines running lengthwise of the stem or pervades the 

 whole surface layer of the stems and main veins of the leaves. 



The corolla is white or greenish white in the ordinary sorts 

 but in the "Nubian" crosses, it shows more or less of the purple 

 prevalent in all parts of the plant. Generally, the other parts 

 of the flower observe the rule of the stems and may be entirely 

 green or show the purple.
