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).
