ESTELITA, Maria Emília Maranhão and RODRIGUES, Ana Claudia. Structural subsidies to stem system caracterization in Cyperaceae. Rev. bras. Bot. [online]. 2007, vol.30, n.3, pp. 401-409. ISSN 1806-9959. http://dx.doi.org/10.1590/S0100-84042007000300006.
Differential anatomical characters between rhizome and scape are point out. Besides the apical meristems activity in both, rhizome and scape, it was observed the presence and activity of MEP (primary thickening meristem) in the stem; the vascular bundles are of mixed origin (from the procambium and from MEP). In the scape, MEP is not present, and the vascular bundles are procambial. However, strong activity of the intercallary meristem was observed, causing the internode elongation.
