(pistil) can be determined. Occasionally the position of the 

 stamens, alternating with the corolla lobes, can be seen. When 

 the number of stainens and lobes do not agree, there are often 

 clues as to how the "extra" one has been added. 



The corolla is usually white but in a few kinds there is a dark 

 color pervading the whole plant and in such, the corolla is of 

 a beautiful purple. In the crosses of the white and such dark- 

 sorts, the color varies greatly, sometimes being colored in other 

 parts and again only in stripes or limited to the margin. There 

 are four such flowers in the plate shown around Figure 5. 



A STUDY OF THE GROWTH OF THE PEPPER FRUIT. 



Plate XIV shows sets of ten each, so far as possible, of 

 twelve kinds of pepper fruits representing ten stages in their 

 development. In this study three sets are included not rep- 

 resented in the engraving. A composite of each stage of the fruit 

 indicates that the record began at 17 mm. and increased with a 

 fair degree of regularity to the ninth stage where 28 mm. were 

 reached from which it decreased one point to 2^ mm. In like 

 manner, the calyx length began at 4.25 mm., ascended to 5 in the 

 middle (5th) stage, then fell below for three stages and finally 

 reached the greatest length (5.25 mm.) in the matured fruit. 



The fruit length of the composite began at 6.25 mm. and 

 arose quite uniformly to 61 mm. when maturity was reached; 

 measurements taken after this stage would show a decline due to 

 the shrinkage which is unusually great, particularly in the long 

 thin-walled fruits. 



The increase in breadth is much less than in the length and 

 the diagram shows an increase from 6 mm. to 29 mm. in a 

 nearly uniform degree through all the stages of development. 



This composite is made up of peppers of both the upright and 

 pendent sorts and the long and short, the narrow and broad, so 

 that an average does not express more than general facts. By 

 taking the five upright and seven pendent types separately, it is 

 determined that the former average shorter stems than the latter 

 as the diagram herewith shows. The line for the upright stems 

 begins with 14.5 mm. and extends in a quite variable line to 23.6 

 mm. while that representing the length of the stems of pen- 

 dent fruits starts at 19.2 and extends also in a zig-zag manner to 

 31 mm. In other words, at all stages of the growth of the 

 fruits, the upright has by 4 mm. a quite uniformly shorter stem 

 than the pendent type.
