PFN000361 (for new species).

E t y m o l o g y. The epithet ufukii originates from the name Ufuk. It is used in honor of Ufuk Akkemik , as he has been one of the most patient persons in my very hard scientific life.

T y p e l o c a l i t y. Near the village of Çayraz in the

Haymana Basin (Ankara) at 32°33′49″ E and 39°28′46″ N .

T y p e h o r i z o n. Canımana Ignimbrite Member of the Yenice volcanics, with age of 24.7 ± 1.9 Ma, i.e. latest Oligocene-early Miocene ( Atıcı et al. 2014).

D i a g n o s i s. Growth ring boundaries distinct and wood ring-porous. Earlywood vessels 1(–2) seriate and transition from earlywood to latewood is abrupt. Tyloses common in wider vessels. Latewood vessels occur in narrow dendritic pattern and clusters. Perforation plate simple. Rays 1–5 seriate and 6–12 per mm. Radial canals are common in rays and their number 1–3 per ray. Ray width generally 1–2 seriate (to 5 seriate around the radial canals). Ray height 5–20 cells. Rays heterocellular and body ray cells procumbent with mostly 1–4 rows of upright and/or square marginal cells ( Akkemik et al. 2018).
