BRICENO-J., A.M.; RANGEL-CH., J.O.  e  MARYS-BOGINO, S.. Wood anatomy and annuity of three rings of species of the dry forest in the Caribbean of Colombia. Polibotánica [online]. 2018, n.46, pp.169-178. ISSN 1405-2768.  https://doi.org/10.18387/polibotanica.46.10.

In transverse sections of the wood of Anacardium excelsum (Bertero ex Kunth.) Skeels., Bursera simaruba (L.) Sarg. and Aspidosperma polyneuron Müll. Arg., the anatomy was characterized and the annual growth rings were differentiated. These species grow in the dry tropical forests of the reserve of Besotes and Rio de Janeiro in Valledupar (Cesar, Caribbean of Colombia). The species studied presented solitary pores or in multiples clusters, of small or medium diameter. The delimitation (marking) of the annual rings of growth was a process with difficulties because the sections of the woods of B. simaruba and A. polyneuron, presented resin spots while the rings of A. excelsum were not easily distinguishable. The results obtained confirm the possibility of differentiating the annual formation of rings in species that grow in dry tropical forests.
