Wood anatomy of Cupressaceae and Araucariaceae indigenous to New Zealand

Summary

Anatomical features of the secondary xylem of Libocedrus bidwillii, L. plumosa, and Agathis australis are described. Anatomical separation between Libocedrus species is practicable. It is also possible to distinguish A. australis from A. vitiensis, grown in Fiji. Axial parenchyma is present in A. vitiensis, but rare in A. australis. In the three indigenous species described here the number of cross-field pits is greater in the upper and lower margins of xylem rays than elsewhere in the ray tissue.
