In the bast-strand, between the two rays, three fibrous bands (y) are drawn ; alternating with them is the soft bast, consisting of sieve-tubes s, of granularly dotted (cambiform) cells, containing abundant starch and protoplasm, and of other, somewhat wider elements, bordering on the fibres, distinguished by clear watery contents and pitted walls. multiseriate zones of radially arranged sieve-tubes ^ In the old root, but not in the stem of the White Fir, I often find, between two radial rows of sieve-tubes, radial bands of parenchyma, which are uniseriate and resemble the medullary rays, but do not lie in the same straight line with the medullary rays of the wood. * Hartig, Forstl.
