pitting. Primary rays with parenchymatic cells and secretory cells (mucilage
canals). Secondary rays with homocellular parenchymatic cells.
Secondary phloem with sieve and sclerenchymatic cells. Foliar traces
with a classic omega pattern. Leaf bases with simple and unbranched
trichomes in a continuous layer on the adaxial side.
