1901] SOME PLANT ABNORMALITIES 353 
Two of the most striking cases of abnormality in Clematis 
are shown in figs. 35 and 36, although similar cases have been 
frequently described, indicating that the displacement and 
coloring of the leaves which are nearest the flowers is a common 
abnormality in the genus. The two figured were both collected 
from the same plant of the “Star of India” Clematis, although 
several seasons intervened between them. In fig. 35 there 
Fics. 31-34.— Abnormal floral organs in a seedling of Clematis Jachmant (of 
Sardeners); 37, normal flower; 32, two sepals united; 73, three sepals united; 34, 
th 
all the sepals united into a gamosepalous perianth. 
appears what at first seemed to be a reversion of the greater 
part of a sepal to an ordinary foliage leaf; the remainder retained 
the form, delicate texture, and rich coloring characteristic of the 
sepals. On the examination of the normal inflorescence, how- 
€ver, it appears that this organ, instead of being a partly reverted 
‘Sepal, in reality is the result of a coalescence of a sepal and/a 
leaf from the node next below the flower. The chief evidences 
of this are found in the absence of one of the leaves from that 
node, and the presence of a marked decurrent line extending 
from the leafy organ down the side of the peduncle to the node.
