326 HilL — Variation in the Flowers of Primula. 
other parts were normal. The other instance of superposed 
petals showed no peculiarity in its androecium, and had 
five sepals, eight petals, and seven stamens. 
No. 7 (Fig. 20) illustrates a portion of a very interesting 
short-styled flower which had eight sepals, eight petals, and 
ten stamens, eight of which were situated at the throat of the 
corolla and the other two inserted upon the receptacle. 
These two had long free filaments, so that their anthers were 
carried up to the level of the others. 
A parallel instance to this was seen in another flower which 
had the normal number of sepals and petals but seven stamens, 
two of which were inserted lower down on the corolla tube 
and had long filaments. The pistil of this flower also was 
very abnormal. It was of a curious shape, broad and short ; 
the stigma was lobed and the style was partly staminal, two 
very pronounced stamens being sessile upon it. 
This is illustrated in No. 8. 
The remaining abnormalities were less interesting, and con- 
sisted of sepals and petals being of an abnormal size, thus 
making the flower zygomorphic. Branched filaments of sta- 
mens were not uncommon, twenty instances being noted. 
The styles of some flowers were longer or shorter than is 
normally the case in the manner already pointed out above.
