|---|---|---|
| L. C. A. Martínez 2012 | Fragment of trunk composed by fundamental parenchyma cells and scattered fibrovascular bundles. Fundamental parenchyma consisting of isodiametric to amorphous cells, with intercellular spaces similar to a lacunar tissue. Stegmatas with spherical echinate silica-bodies in axial series. Tabular parenchyma 1 to 3 cells wide, sheathing the fibrovascular bundles. Fibrovascular bundles irregularly distributed, with a great reniform to subcircular sheath composed of sclerenchyma fibers. One phloem strand. Many and small protoxylem vessels. Metaxylem with a mean of 3 vessels (2–6) by bundle, with scalariform thickenings, and scalariform and simple perforation plates. |
