298 METAMORPHY. 
point of view. OC. Morren has given the name adeno- 
petaly to a case wherein one of the glands at the base 
of the petals in Lopezia was replaced by a petal.’ A 
similar change may be seen in the double Oleander. 
Staminody of the bracts—An instance of this has been 
already alluded to in Adies excelsa, as observed by 
Prof. Dickson, and in which some of the bracts were seen 
assuming the form and characteristic of the stamens 
see ante: p. 192. Signor Licopoh met with a similar 
substitution of anthers for bracts in Melianthus major.’ 
Staminody of the sepals and petals——In the first named this 
is of very rare occurrence. M. Gris has recorded an 
instance in Philadelphus speciosus’ which appears to be 
the only case on record. The corresponding change in 
the case of the petals is far more common. De Can- 
dolle cites in illustration of this occurrence flowers of 
the common haricot, in which the ale and carina of the 
corolla were thus changed.‘ There is in cultivation a 
form of Savxifraga granulata wherein the petals are 
replaced by stamens, so that there are fifteen stamens. 
A similar change has been observed in Capsella bursa- 
pastoris. 
Cramer figures and describes a stamen occupying 
the place of a petal in Daucus Carota.’ Turpin’ de- 
scribes a similar occurrence in Monarda fistulosa, m 
which the lower lip terminated in an anther, but this 
may have been a case of adhesion. Moquin cites 
from Chamisso, Digitalis purpurea, and from Jussieu, 
Asphodelus ramosus, as haying presented this change, 
and Wiegmann’ has seen anthers developed on the 
awns of Avena chinensis. In semi-double flowers of 
Ophrys aranifera and Orchis mascula, the lateral petals
