Comments
General finishing qualities are rated as good

The wood is similar in properties to other Boxwoods (Buxus , Gossypiospermum ). Boxwood was originally the trade name of Buxus sempervirens from Europe and eastern Asia. The trade name has been extended to include other species that are botanically dissimilar but which resemble true boxwood in general characteristics. San Domingo boxwood (Phyllostylon brasiliensis ) is among the more important of the boxwood-like species
