IRREGULAR PELORIA. PAS bo. 
part of the receptacle between the insertion of the 
petals and that of the stamens is dilated so as to form 
the spur which is so characteristic in the genus. The 
position of the spur in a line with the posterior sepal 
has led many botanists to consider it as a process of 
that sepal, but the fact of its being situated within the 
insertion of the petals 1s conclusive as to its receptacular 
origin. In the flowers exhibited the supernumerary 
spur (as if to show its want of connection with any 
sepal) was placed exactly between a lateral sepal and 
one of the anterior sepals, sometimes on the one side of 
the flower and sometimes on the other. These addi- 
tional spurs were precisely similar to the normal ones, 
except that they were a little shorter. This abnor- 
mality, although at first sight seeming to indicate a 
pelorian tendency, is no approximation to regularity, 
from the fact of the extra spur being differently placed, 
with regard to the sepals, from the normal one.” 
Peloria of this kind, when perfect, is very often 
associated with other alterations. Change of direction 
is one of the most common of these; the usually 
drooping flower becomes erect, the stamens and style 
also are changed in direction, while, not unfrequently, 
either the one or the other (most often the stamens) 
are entirely suppressed. With this suppression an 
increase in the size of the flower very generally coin- 
cides. The number of parts is also frequently im- 
creased; thus, in Antirrhinwm majus the corolla, when 
subjected to peloria, is very generally six-parted, and 
has six stamens. Fusion of one or more flowers is also 
a common accompaniment of peloria, as in Digitalis 
purpurea, in which plant prolification often adds in- 
creased complexity to the flower. 
It has been stated by Moquin and others that the 
uppermost flower of an inflorescence is the most subject 
to peloria; the uppermost flower of Teucriwm campanu- 
latwm, for instance, is very generally regular. In Calceo- 
lavia it is the central terminal flower which is usually 
peloriated ; on the other hand, in Iinaria and Antirr-
