Diagnosis

Vessels rounded or angular in outline, mainly solitary, numerous (ca. 100 mm-2); tangential diameter up to ca. 60 lm; vessel element length up to 890 lm. Perforation plates scalariform with up to 18 bars. Intervessel pits mostly scalariform and transitional to opposite and alternate, 4–8 lm in vertical size, with rounded margins. Tangential and radial fiber walls with circular bordered pits. Axial parenchyma diffuse, sparse. Ray frequency up to 8 per mm. Rays uni- and multiseriate up to four cells wide, heterocellular, with 1–3 (up to 6) marginal rows of square and upright cells. Prismatic crystals occur in square and upright ray cells.
