In this paper we report new data about two wood species that could play a role in the Portuguese forest as raw material for the paper industry: Cupressus arizonica and Cupressus sempervirens. Results on the behaviour of wood samples taken from 16 year-old trees, (two per species and two height levels), have shown lower kraft pulp yields than reference pine softwoods, as a consequence of higher lignin content. The pulps from C. sempervirens present values of fibre lenght and coarseness slightly lower than the Nordic Pinus sylvestris, but properties of pulp fibres from C. arizonica are significantly lower.
