Attention is to be called here to the fact that comparisons of leaf forms in plants of this kind are permissible only between organs on corresponding por- tions of shoots. The laminae were more bluntly toothed than those of the parent type, and the midribs occasionally bore a tinge of red, while the entire shoot including the leaves of the upper part of the stem showed a tendency to the formation of anthocyan. The physical qualities of the leaf were strikingly different from those of the parent, perhaps the most noticeable feature being the great brittleness of the leaves and stems of.
