ters known to the botanists as the "panicle," where instead of one 

 axis there are two or more, as shown at 5, 8 and 13. 



In the breeding together of a variety with a raceme and one 

 with a panicle, there arise all intergrades. Thus at i is shown 

 the confusion that is met with in a cross showing strongly the 

 "Currant" blood. Here two clusters are nearly united at the 

 base, and the upper one — with a single fruit close to its 

 base — is forked a short distance from the point where it leaves 

 the main stem. 



In the dwarfs, the compactness that characterizes the stems 

 and foliage is also present in the flower cluster; this is shown at 

 3 where a "half-blood" of "Currant" is given with its forked, 

 thick set branch of fruits and a basal branch with Ijut a single 

 tomato. 



A much more open cluster is shown at 4 where a long plum- 

 fruited cross is shown in striking contrast with the previous 

 one. 



Perhaps of as much interest to the breeder are the mingled 

 clusters that arise, namely, those in which leaves form upon some 

 of the branches where fruits might otherwise appear. At 14, 

 for example, the cluster is made up quite largely of foliage ; the 

 upper cluster in 12 ends in a well-formed leaf and at 11 the large 

 "potato" leaf is intimately associated with the fiuits. At 7, the 

 seemingly central flower is much larger than any others and it is 

 difficult to make out clearly the relation of flower and foliage 

 structures. 



As a rule, the flower clusters are quite regularly disposed upon 

 the upper side of the naturally inclined stem and arise some 

 inches below every third leaf. At 6, 12 and 16 are shown 

 instances where two clusters are near each other. Occasionally 

 the stem of the flower cluster is fused with the main branch for 

 some distance as shown at 10 and 15. 



THE TOMATO CALYX. 



Some observations have been made upon the tomato calyx. 

 As might be expected, all of the simpler forms of fruits, that is, 

 the nearest to the wild state, and having but two seed-cavities, 

 as a rule show only five lobes to the calyx and these are generally 

 long and slender. The number of stamens in such flowers agrees 

 closely with that of the calyx "teeth" and the same is true of the 

 lobes of the corolla. In other words, the number five prevails in 

 all parts of the flower excepting the pistil (fruit) where it is
