Original diagnosis/description

Growth ring boundaries distinct, with 1 (–2) rows of flattened axial parenchyma cells. Wood diffuse-porous, vessels mostly in short radial multiples of 2–4 (–6) cells, and solitary. Solitary vessels circular in general, vessel cells in radial multiples, tangentially flattened, some vessel cells triangular at tips of radial multiples. Mean vessel tangential diameter 50–100 μm, vessel frequency 40–100 per mm2 (Pl. 15A, B). Axial parenchyma diffuse, in 1 (–2) rows of marginal bands (Pl. 15B, C). Rays exclusively uniseriate, 5–20 (–35) cells high. 4–12 rays per mm (Pl. 15D, E); 2–4 cells per parenchyma strand (Pl. 15E). Perforation plates simple (Pl. 15F). Vessel-ray pits simple, large, slightly honeycomb-like (Pl. 15G). Vascular and vasicentric tracheids absent, septate fibres present, axial parenchyma common (Pl. 15H). Rays homocellular; all ray cells procumbent (Pl. 15I).
