Flowering and Fruiting Data. — The flowering season indi- 

 cated is that of petaliferous flowers. Under "fruit of cleisto- 

 genes" is given the approxinilate time when ni'ature capsules 

 are usually present. 



The flowers of violets are of two kinds. The showy petal- 

 iferous blossoms appear early, and only regularly produce fruit 

 in a few species. The small green apetalous flowers (cleisto- 

 genes) appear later, and generally produce fruit abundantly. 

 The characters of the cleistogenes, the seeds and the capsules, are 

 very important in the systematic study of the genus.
