104 THE FORMS OF FLOWERS IN VALERIANA DIOICA. 
Fig. 27. Longitudinal section of the young bud of a flower of the type А. In the young 
bud the style only reaches to the level at which the stamens are inserted (cf. the 
preceding figures in which the style has reached to the top of the corolla-tube). 
ig. 28, Flowers from one plant showing unusual elongation of the corolla-tube below the 
spur. In these flowers, although the style reached a length of from 1:7 to nearly 
2 mm. it was quite invisible from above, and, as shown in the long. sect. (fig. 28 a), 
it did not reach above the level at which the stamens were inserted. Subsequently 
this plant bore numerous flowers of the type А, and a few of the type В; in which 
the variation shown in these figures was not present.

Figs. 29-31, Flowers from a plant varying between types B & C. 
. 29. A flower of type C, displayed by splitting the corolla. This flower was well open 
and apparently about the same age as that shown in fig. 30, but not аз old as that 
shown in fig. 31. 
Fig. 30. A flower of type D, displayed by splitting the corolla.

Fig. 81. An old flower whose anthers had fallen, displayed by splitting the corolla; from 
the same plant as the two preceding. 
Figs. 32-37 represent the various types of flower which were all borne on one male 
plant. All the flowers represented were fully mature, while the 
anthers had withered in that represented in fig. 83, and had fallen in 
that represented in fig. 37, which had the shortest style of all.
