46 THE NATURE-STUDY OF PLANTS 
lines radiating from the centre like the spokes of a 
wheel, but we look in vain for the style, for there is 
none. 
Again, in the Wallflower we have a long thin 
ovary, and two divergent stigmas topping a very 
short style. 
Now, I do not wish to worry my readers with 
technical terms, but sooner or later the student will 
have to know about them, and I want them both to 
remember that the ovary, the stigma, or stigmas, and 
the style, when there is one, are 
known collectively as the pistil. In 
all the three plants which I have 
mentioned the pistil is a single 
undivided organ in the centre of 
the flower; but there is another 
kind which is to be found in such 
well-known plants as the Marsh- 
= marigold, the Bramble, the Yellow 
Mia. 4 Fistil of Stonecrop, and the less commas 
1e Marsh-marigold. 2 
x 3. Flowering-rush. In the first two 
the number of parts varies, in the 
Stonecrop it is five, and in the 
Flowering-rush nine, and in every case each part has 
its own stigma upon a style that is often minute. 
We can understand, then, that there is a good deal 
to be learnt about the pistil from our own wild flowers, 
and, similarly, we can find a very great range of variety 
‘in the form and arrangement of the stamens. Full 
information can be gleaned from any good text-book, 
and we should remember that a stamen consists of a 
stalk called the filament, and a bag at the top which 
contains the pollen grains, and is known as the 
anther, 

Stg., stigma; St., style.
