CARDOSO, Cristiano Marcelo Viana and SAJO, Maria das Graças. Leaf venation in Brazilian species of Myrtaceae Adans. Acta Bot. Bras. [online]. 2006, vol.20, n.3, pp. 657-669. ISSN 1677-941X. http://dx.doi.org/10.1590/S0102-33062006000300016.
Leaf venation in the subfamily Myrtoideae Nied. (Myrtaceae) was examined and the unique features in each subtribe were defined using leaves of 44 species belonging to subtribes Myrtinae (9 genera), Myrciinae (5 genera), and Eugeniinae (8 genera). Although the camptodromous-brochidodromous pattern is dominant among the species, the mixed acrodromous-brochidodromous pattern is also present. For each species, secondary venation pattern, ultimate marginal venation, tertiary venation and areolation, as well as presence or absence of the intramarginal vein were described.
