302 METAMORPHY. 
Pistillody of the perianth—The passage of the segments 
of the perianth into carpels has been observed fre- 
quently in Tulipa Gesneriana, the change in question 
being generally attended by a partial virescence. M. 
Gay is said by Moquin to have observed a flower of 

Fria. 160.--Flower of tulip, showing vertical attachment of a leaf, and 
also the existence of ovules on the margins of the segments of the 
perianth. Some of the parts are removed. 
Crocus nudiflorus in which the segments of the perianth 
were cleft and fringed at the same time, so that they 
presented the appearance of the stigmas. 
Pistillody of the sepals—In some double flowers of the 
garden pea communicated by Mr. Laxton, among other 
peculiarities was a supernumerary 5-6-leaved calyx, 
some of the segments of which were of a carpellary 
nature, and bore imperfect ovules on their margins, 
while at their extremities they were drawn out into 
styles."
