AN ABNORMAL STEM OP LONICERA PERICLYMENUM. 
By Christine E. Burgess, B.Sc. 
[With Twelve Figures in the 'Text]. 
N abnormally developed stem of Lonicera Periclymenum was 
put into my hands. At first sight it was quite unlike a 
normal shoot, but there was very little departure from the usual 
type of anatomy beyond displacement. The specimen appeared, 
with two others of similar construction, as the only peculiar branch 
on the parent plant. 
The normal shoot bore whorls of leaves, either two or three at 
each node. An interpetiolar ridge was formed by the union of 
adjacent leaf bases at the node. In the axil of every leaf a bud or 
branch was found (Fig. I).
