irregularities and the style may be strongly flattened, suggesting 

 that the fruit may be corrugated or broad bell-shaped. 



The lower portion of the plate deals with the single blossoms, 

 those to the left (9) being of the Chinese species, followed by those 

 of the hybrid (10), and to their right (11) are several of the 

 American kinds. The corolla is often with five lobes in the 

 smaller fruited kinds bearing alternating stamens ; but six points 

 to the "star" are the rule in some sorts, while seven and eight 

 lobes are not uncommon especially among the large-fruited 

 varieties, the fruits of which become broad and somewhat fiat. 

 Occasionally the tendency to become doubled is quite manifest as 

 seen in the last two flowers (12) where the upper portion of each 

 stamen has become petal-like even to the purple color character- 

 istic of the dark-fruited sort in question. 



UPON CHANGE IN FORM OF GROWING FRUITS. 



In this study, ten fruits were taken from the same plant that 

 formed a series from the time when the corolla and stamens 

 were falling, until the fruit was of market (or mature) size. 

 Additionally, measurements were taken of the stem (peduncle) 

 and the adhering calyx. 



Four kinds of widely different eggplants are shown in Plate 

 VII. It is seen that the cross, "Black Snake" upon "Round 

 White," had very generally the longest stems and the "Chame- 

 leon," the shortest. It is also shown that the peduncle was a 

 subject of elongation, the "Dwarf Purple" extending from 23 

 to 63 mm. The "White Egg" showed remarkable variation, all 

 of which obtains upon the same plant. (The stem of the ma- 

 ture fruit shown at the left end of the series was broken and 

 the record is necessarily incomplete.) 



A composite of the forty fruits made up for the four series 

 indicates that the length is practically doubled (t,2 to 64 mm.) 

 and the increase is probably quite uniform from the blossom 

 to the ripe condition. The calyx of the same set in the com- 

 posite increases from 22 to 39 mm. in length, and is probably 

 uniform in the development of any particular fruit. The 



"Chameleon" is quite different from the three American sets in 

 not showing any steady increase in size of calyx. 



In length of fruit, there is a great range of variation among 

 the four sets: the "White Egg" somewhat more than doubled 

 its length ; the "Chameleon" trebled its length ; the "Dwarf 

 Purple" started at 2.5 mm. and went to 132 mm.; while the 

 "Black Snake-Round White" went from 10 to 205 mm. The
