Text-figure 11 shows another injured plant where the wound, though 
greater in area, was rather less extensive in a transverse direction, and the 
stem took a curved position with the tear on the upper surface. The second 
node fell to the ground and roots developed both above and below it on the 
convex side. In addition to this, minute roots appeared on the upper surface 
of the stem above the wound. This appeared to be another abortive attempt 
to reinforce the food-supply, and here, too, as in the previous case (text- 
fig. 10), the roots arose above the wound, even though it was on the side of 
the stem furthest removed from the soil. 
Ета. 12 a.— Plant with an extensive wound in the lower half of the supercotyledonary 
‘internode, and showing a profuse development of roots from the upper surface of 
the stem. 
Fra. 12 6.—Side view of the same wound. Root x attained a length of eleven centimetres 
and so reached the soil-level. 
In text-figs. 12а and Û are shown respectively the front and side views 
of a very extensive wound. In this plant there was a tear of about six 
centimetres in the bottom half of the first epicotyledonary internode, but the
