Fig. 86. Rhizome of Dendrobium. Each year the Dendrobium sends up a food-storage 



stem, or pseudo-bulb, the growth arising from the scales at the base of the parent 



stem. The leaves have fallen from the stem at the right; the center stem may bloom, 



and the stem at the left is ready to produce leaf growth.
