PATHOLOGIC PLANT ANATOMY 361 there was a pair of guard cells for every 204 epidermal cells. The for- mation of the hairs on the edge of the ocrea of Polygonum amphibium is entirely suppressed in the form natans, which is grown under water, while they are present in the form terrestre. The modification of the mesophyll tissue in homoplasia is due to the character of the environ- ment. Plants cultivated in places saturated with moisture, or after infection by fungi or animals, show a homogeneous development of the mesophyll. In homoplasia, the vascular bundles decrease in number, the mechanic tissue degenerates and the collenchyma sometimes^does not.
