Abstract Abstract Growth eccentricity and reaction anatomy in horizontal or inclined branches of Drimys winteri J.R. et G. Forst. and five native New Zealand tree species are described. The species investigated show characteristic distribution patterns of growth eccentricity along the branch length. Anatomical differences between wood from the lower and upper sides of inclined branches occur in all six species investigated. Compression wood is a regular feature in Phyllocladus alpinus Hook. f.; as is tension wood in Nothofagus solandri var. cliffortioides (Hook. f.) Poole. Myoporum laetum Forst. f., Myrsine australis (A. Rich.) Allan, Pennantia corymbosa J.R. et G. Forst., and Drimys winteri develop neither compression wood nor tension wood.
