Growth ring boundaries distinct with 2–3 rows of flattened latewood tracheids. False rings commonly present. Transition from earlywood to latewood indistinct. Tracheids generally circular, and intercellular spaces clearly obvious and occur throughout the wood. Normal axial resin canals absent. Axial parenchyma appears both diffuse (in the transition from earlywood to latewood and within the latewood itself) and tangentially zonate. Rays uniseriate, and sometimes partly biseriate. Ray height is 1–6 (max.16) cells. Tracheidal pits on tangential walls common and 1–2 seriate, irregular or slightly alternate. The rays with one cell height conspicuously longer. Transverse end walls of axial parenchyma cells are nodular and smooth. Ray tracheids absent. End walls of ray parenchyma cells nodular and smooth, horizontal walls of rays sparsely pitted. Tracheid pitting in radial walls of the earlywood is uniseriate and biseriate, opposite, frequent, contiguous, and sometimes spaced. Cross-field pitting is cupressoid with 2–3 (–5) pits per cross-field.
The epithet “acarcae” originates from the surname of Dr. N. Neslihan Acarca Bayam who worked on the petrified woods in the Galatian Volcanic Province for her PhD in Turkey. It was the first PhD on petrified woods in Turkey.
