The buds under consideration are the terminal buds. The scales in the former species (Fig. 1) are somewhat tapering, although thick and broad throughout their entire length. Those of the latter (Fig. 2) are broad at either end, but contracted at the cen- ter. In both cases a series of narrow grooves, running parallel from the raised ridge in the middle to the edges on either side, indicate the x i!4 leaflets of our transformed leaf. This portion, l~'3m ' however, is confined to the tip; hence the greater part of these scales must be composed of the common petiole of a compound leaf. 2. The same structure is visible in Fraxinus quadrangu- lata, Mx. In this case the buds are not long, as are those of Juglans, but short and conical. The outer scales (Fig. 3) show the same ribbed structure, indicat- ing leaves. In this case we again have scales composed chiefly of the common petioles of compound leaves, but the leaflets still remain attached in a rudimentary con- dition, as in the case of Juglans. 3. In Negundo aceroides the scales (Fig. 4, a) are of an ovoid shape, and bear at the tip three small leaflets, which, however, â Ju shrivel up and fall off in winter, leaving a scar on a K each scale at the tip (Fig. 4, b). In this plant, there- f§H fore, the scales consist only of the remaining com- mon petiole of a compound leaf. In other members of the genus Fraxinus, where indications of leaflets never ap- pear, the scales may be considered as composed only of the common petiole, the leaflet being obsolete. 4. Sassafras officinale has scales bearing such plain veins that we may confidently attribute their origin to the blades of leaves. 5. In Smilax hispida the petioles remain during winter half surrounding the bud and acting as one of the outer scales of the hibernaculum (Fig. 5). The tendrils, ' which are
