- Diagnosis
- Tracheidoxylic secondary wood with unequal growth rings, sometimes marked at the rim by series of axial resin ducts, probably traumatic, one per bundle, round to oval, variably sized (rd/tgd = 40-150 / 30-75 µm). Tracheids polygonal in cross section with meats, thick-walled, polygonal-rounded lumina with rd/tgd = 25-40(60) / 20- 30(40) µm, smaller in late-wood, in (1)2-5 interradial regular rows, 900-1400 cells on sq. mm. Tangential pitting absent, radial pitting protopinoid, 1-2(3)-seriate, with circular borders, d = 16-20 µm, sometimes compressed, spaced or contiguous disposed, opposite with crassulae or alternate and hexagonal shaped, with circular to elliptic apertures of 5-7 µm in diameter. Septate tracheids in the late wood, usually forming a sheath around the resin ducts. Parenchyma scarce, as rectangular, high, thick-walled pitted cells with horizontal thinner walls, unpitted, smooth or few knotted. Rays 1(2-3)-seriate, uniseriates dominant and of 1- 18(28) cells high, bi- and triseriates rarer. Ray cells unequal in height oval to round, deformed, thick-waled, without lateral intercellular spaces. The density is of 16-20(23) rays on tangential mm. Radially-homocellular, rarely short upright ray cells, thick-walled, with pitted horizontal walls and thinner, knotted, oblique or arcuate tangential walls, without indentures. Cross-fields with 1-3(6-10) cupressoid pits solitary or in one vertical pair, in rossete, or alternate disposed in 1-2 horizontal rows or more numerous, as typical araucarioid pitting.
