does occur, as in some palms, is due to expansion of the first-formed cells, not to new layers of cells added between the bark and wood, as in the dicotyledons ( 162). Structure of Corn Stalk. (L) Cut a dry corn stalk (stem) transversely. Note the smooth rind (not true bark) on the out- side, and inside the rind is the soft pith throughout which the fibro-vascular bun- dles are scattered irregularly. Where are the bundles largest ? Where are they most abundant ? Suggest a reason for such ar- ra...ngement. Split a stalk lengthwise, and the fibro- vascular bundles appear as long threads which are easily pulled out. Trace these long threads through nodes. Do they all continue upward or do some of them turn toward the rind at the nodes ? Try to trace some of the bundles out into the bases of leaves left on the nodes. Stand a piece of green corn- stem for a short time in red ink, and then cut both transversely and longitudinally in several places, and find out where the colored liquid ascends the stem.
