FORMS OF FLOWERS IN VALERIANA DIOICA. 103 
Figs. 7-9. Flowers of an abnormal female plant. The corolla is relatively very 
large, and, except in one flower, always divided into more than 5 lobes. 
Fig. 7. Side view of a flower showing supernumerary corolla-lobes. Fig. 7а. The same 
flower after splitting the corolla. Fig. 7 0. View from above. 
Fig. 8. Flower with two separate styles, displayed by splitting the corolla. Fig. 8а. View 
from above. 
Fig. 9. View from above of a flower with supernumerary corolla-lobes. 
Figs. 10-12. Flowers of а female plant which approached the hermaphrodite type

in the large corolla and the large staminal rudiments (see p. 93). 
A young flower, in which the style had not yet elongated, displayed by splitting 
the corolla. 
Side view; fig. lla, view from above, of a mature flower of the same plant. 
Fig. 11 0. The same flower after splitting the corolla. 
Style from another flower of same plant, to show the splitting of the stigmatic 
lobes which occurred in many flowers. 
Flower of a sister plant to the foregoing. The anthers were reddish in colour and 
produced a small quantity of pollen. Fig. 13, the same flower displayed by 
splitting the corolla; fig. 13a, view from above. 
Flowers of the typical “ hermaphrodite” type. It may be noticed that the style 
does not much exceed the corolla-tube in length. The anthers produced good 
pollen in fair quantity. Fig. 14, side view ; fig. 14 a, the same flower displayed 
by splitting the corolla. 
Figs. 15-18. Flowers of an hermaphrodite plant which approached the form 
of the long-styled male flower. 
A flower in which the anthers had not dehisced, displayed by splitting the corolla, 
to show the short style of the young flower. 
Side view of a mature flower whose anthers had dehisced. Fig. 16а. The same 
displayed by splitting the corolla. 
Similar flower seen from above. 
Ovary of a flower from which the corolla dropped. 
Figs. 19 & 20. Cymes from two male plants, offspring of the same cross, one long-styled

(type A), the other short-styled (type E), showing the marked difference in the 
size of the ovary of the central (oldest) flower of the cyme. In the left-hand 
flower of tig. 19, the long style is visible, standing up in the corolla-tube. (The 
magnification is half that used for the other figures of male flowers.) 
A flower of the plant represented in fig. 19, displayed by splitting the corolla. 
Ovary of central flower of cyme, the corolla having fallen, of the same plant. 
Flower from another plant, displayed by splitting the corolla. The flower 
is of type A, but the style is rather shorter than in the plant represented in 
fig. 21. 
Ovary of central flower of суше of the same plant, for comparison with fig. 22, 
Flower of the type A, from another plant, seen obliquely from above. 
Ovary of a flower, the corolla having fallen, from the same plant. А comparison 
of figs. 22, 24 & 26 will show the variation in the size of the ovary which exists 
in different long-styled plants.
