60 STRAWBERRY. 
on which the changed ovaries (ov.), represented by leaves 
may be seen; at the top the second flower is cut open 
perpendicularly, showing at s. the sepals, p. the petals, 
within which may be seen some stamens and ovaries. 
98. But the most conclusive evidence is afforded in 
the Strawberry of the Alps of Europe, which some- 
times becomes transformed from the state of flower to 
that of leaves. Pl. 20. f. 1. is a representation of 
such a flower: the calyx is of the usual form and 
appearance, while the petals (p.) assume a green 
colour, and a lobed form, furnished with very fine 
hairs; (f. 2. is a petal magnified.), The stamens which 
are about twenty in number, are enlarged into green 
leaves with petioles, some are three-lobed (f. 3.), while 
others are simple; most of them are also furnished 
with two small yellow bodies (a.) at the base of the 
blade, which are the anthers in a rudimentary state. 
The carpels (f. 4. ¢.) also degenerate into leaves, and are 
arranged spirally on the receptacle, which becomes 
juicy as the flower grows. ‘These carpels contain very 
minute leaves (f. 4. 0. 5. 0.), which represent the ovules. 
In this singular flower all the several organs destined 
to provide for and protect the seed, preserve, as it were, 
their original condition of green leaves. 
99. A proof of another kind can be advanced to 
strengthen the statement, that all the organs of a 
flower are of a leafy origin : by which it is not intended 
to imply that these parts ever have been leaves, but 
are organs which may be produced as leaves, or parts 
of a flower, according to the way they may be affected 
in the growth of the plant.
