キカラスウリの莖の異常肥大成長に就いて

抄録

Abnormal structures were observed in the stems of Tricosanthes japonica Regel, in the radial margin of the xylem plate and around the inner phloem, as well as in the tissue of cortex. In these abnormal structures in the margin of the xylem and in the inner phloem there exist small vessels differentiated as a result of activity of secondary cambium cells. Such type of abnormal thickening does not correspond to any type hitherto described.
