Description

Belize is home to two commercially important species of Dalbergia, D. stevensonii and D. tucurensis, whose overall appearance and wood anatomy are similar. D. stevensonii is protected from commercial harvesting, whereas D. tucurensis is not. Therefore, reliable methods for separating the two species are important. Comparison of samples from the Center for Wood Anatomy Research at the Forest Products Laboratory demonstrated that density can reliably separate the species. Freshly cut surfaces of D. stevensonii were sometimes fluorescent, but they never were in D. tucurensis. Ethanol extracts were sometimes violet in D. stevensonii, but never in D. tucurensis.
