The terminal internodes of a rhizome of Cyperus rotundus L. may terminate in a tuber, or in a basal bulb bearing an aerial shoot. When mature both of these organs are characterized by compressed and swollen internodes each of which may be about 0.2 cm long. At each node there arises a scale leaf in the axil of which there is usually one bud. One or more buds on each tuber or bulb may grow into a new rhizome, which subsequently produces a tuber or basal bulb, thereby repeating the vegetative reproduction process. Since there are no axillary buds in the axils of the scale leaves on the rest of the rhizome length, tuberization and / or formation of basal bulbs is of prime importance in the vegetative reproduction of C. rotundus.
