392 MR. W. B. HEMSLEY ON A SPECIMEN OF 
is termed false peloria. The specimen I now exhibit is an example of 
true peloria ; all the spurred organs being of the inner or petal series 
of the floral envelope. Аз in my former exhibit, all the flowers, originally 
eleven in number, are transformed, and the ovary is not twisted. The 
spurs in some of the flowers are of unequal length, and the limbs or blades 
are a little unequal in size and shape. In other flowers the three spurs 
and three blades are almost uniform in size and shape. But the flowers 
Front view ofa flower with unequal spurs, about twice natural size, 
have not become symmetrical as to the sepals and petals, the st aight 
spurs being directed upwards, radiating through about a quarter of a 
cirele; in other words their divergence is about forty-five degrees. The 
blades of the petals have undergone very little modification ; much less 
than the blades of the sepals of the other three-spur specimen to which 
I have referred. 
Bo far as my investigations go, this is the first record of what may be 
termed lip-peloria with spurs, and my colleague Mr. В. A. Rolfe tells me 
that no other instance has come under his observation. Concerning the 
occurrence of peloria in orchids generally, Penzig says*: * The formation 
of peloria is very frequent in orchids, usually occurring, however, in 
solitary lateral flowers, not in whole inflorescences.” Concerning peloria 
in Platanthera bifolia, he says T : “several instances of peloria have been
