grown by Mr. E. J. Kohl. The monstrosity is a reversion. One sepal 
is prolonged and divided and is also partly green, i. e., leaf-like in two 
respects (Fig. 12). Another monstrosity is a variation in the head 
of Calendula grown in the writer’s garden. Instead of the usual head, 
some flowers are changed into small heads set on long pedicels. This 
is a floral proliferation of the inflorescence (Fig. 11). A number of 
such abnormalities occurred on one plant. The third monstrosity is 
a peculiar modification of a spruce cone (Picea excelsa L.) in which a 
cone bearing microspores (pollen) developed from a terminal bud, the 
normal place for a normal megacone. No leaves were produced from 
the bud. The lower part of the cone consists of very small, loose scales 
with rather large microsporangia full of microspores. The middle zone 
is made up of sterile scales similar in form to megasporophylls. This 
is evidently a case of heterogamy. (Fig. 10.) (Collected by author on 
Purdue campus.) 
Peloric forms have been of little significance in horticulture (4). 
Peloria and other abnormalities, however, are of biological interest in 
discovering certain natural laws. All kinds of organic abnormalities 
are worth investigation, as is clearly shown by many of our cultivated 
plants which, like the navel orange, Fultz wheat and other kinds of 
wheat, the copper beech, the Shirley poppy, and cupid sweet pea, all 
of which arose from sudden variations or mutations.
