REGULAR PELORIA. 993 
erect, regular, five stamened flowers, but these are 
probably cases of irregular peloria. 
A solitary flower of Pedicularis sylvatica was found 
by the Marquis of Stafford near Dunrobin Castle in 
Sutherlandshire, in which the usual ringent form 
of the corolla was replaced by the form called salver- 
shaped. There were six stamens, four long and two 
short. Sir W. Hooker and Mr. Borrer are stated to 
have found a similar flower in the same locality in 
1809." 
The passage of hgulate to tubular corollas among 
Composite is not of such common occurrence as is the 
converse change. I owe to Mr. Berkeley the communi- 
cation of a capitulum of a species of Bidens, in which 
there was a transition from the form of ligulate co- 
rollas to those that were deeply divided into three, 
four, or five oblong lobes. These then were instances 
of regular peloria. 

Bae. 121.—Flower of Cattleya marginata. Lip replaced by a flat 
petal. 
Tn Orchidacee a similar change is not by any means in- 
frequent ; in a few, indeed, a regular flower is the normal 
! See ‘ Trans. Linn. Soc.,’ vol. x, p. 227.
