The Ohio naturalist, Vol. 1, No… (1900)
“ In no case do we think it admissible to say that the adaptation is primarily for the purpose of propagation, although this may be a very important incidental result in such plants as the willows when growing in wet places. In the case of Ampelopsis cordata, the only reasonable explanation seems to be a preparation for the winter condition, since the branches which are shed do not ripen and the plant has an admirable method for shedding its leaves. The slender branches would be in great danger of being killed by the cold of winter. ”
