Some- times they are reduced to two small rows, or rarely disappear entirely. Sometimes the hypodermal fibers cover all the lower side of a leaf, as in many species of Festuca. In such cases there may be none, a few, or many on the upper side, or it may be entirely covered excepting a few lines on the sides of the veins where the stomuta are found. The cells of the bands covering the ma. i xfia-(ii'uvai-Jouve.) parenchyma are larger than those which are over the veins or hypodermal fibres. On the upper surface of the leaf, these bands are often cut in two by bulliform Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Beal, W.
