Original diagnosis/description

Growth ring boundaries indistinct. Wood diffuse-porous and vessels arranged in radial multiples, and generally in a dendritic pattern (predominantly flame-like). Radial clusters of vessels very common and solitary vessels rather rare (Pl. 3A, B). Fibres thick-walled. Axial parenchyma commonly apotracheal diffuse and diffuse-in-aggregate, and in narrow and short tangential bands (Pl. 3A). Ray width 1–3-seriate; in some rays, 1–4 rows of square marginal cells present. Aggregate rays occasionally present. Rays per mm ≥12, ray height 1–30 cells (Pl. 3C, D). Rays heterocellular, body ray cells procumbent with one row of square cells. Perforation plates simple (Pl. 3E).


The epithet “kayacikii” honours Prof. Dr. Hayrettin Kayacık, the founder of the Forest Botany Department of the Faculty of Forestry at Istanbul University.
