The bundle in the smaller Club-mosses (Selaginella) is much like a single plate of the preceding. There is in each bundle a central plate of tracheary tissue, consisting of a few narrow spiral vessels in its two edges and a re- maining mass of scalariform vessels (Fig. 30). The tra- cheary portion is surrounded by a tissue of elongated, thin- walled tissue which is, at least in part, a sieve-tissue. In.
