It was fupnd expediënt to remove the capsules a month 

 after fertilization. By this time they had reached a size 

 closely approximating to that of maturity. The fruit (fig. 8) is 

 oblong-elliptical, acute, and clothed with fine hairs. It com- 

 monly hangs downwards, or is pushed under the leaves, 

 by: the beiiding of the pedicels. The scape usually assumes 

 a horizontal position. In one instance (that illustrated ,in 

 Fig. 8) two scapes.arose from a common basal axis. 



The pollen failed to act in only four cases out of the 

 eighty, namely, in two of the 2"^ set, and in two 



ofthe8*\, . ,. ■ . :.: .H - ' ' 



There is no apparent reason why pqllinatio^n in these 

 cases should have failed. 



No attempt was made to count the ovules; but by mi- 

 cfoscopic examination of them, and by measurement of the 

 capsules, it was found possible to get sufficiently reliable com- 

 parative results. After careful tabulation of the measure- 

 ments and general observations, one failed to find that any 

 advantage accrued from cross-fertilization. Good fruit was 

 produced in all the ten sets of experiments, the general ave- 

 rage of excellence being singularly equal overall. As a rule, 

 the largest fruits (15°" in length) were derived from the first 

 and second flowers of the cyme. Those borne on later 

 branches were often poorly developed, no matter how 

 fertilized. • . " 



It is obvious, howeyer, that it would have been more 

 satisfactory to have had opportunity of eounting the seeds, 

 and of noting. theirgerminating power. 



All the fruits on the above plants were of one shape. It 

 has been mentioned (1) that fruits of two different shapes 

 occur in Saintpaulia. As has been already remarked, the
