Yes, but... look at this study:
"Summary: Foliar architecture of native species of Myrtaceae from Argentina I: Groups "Myrcia","Myrceugenia" and "Plinia". Nineteen species of native flora were studied to find patterns of leaf architecture to differentiate the Argentinean species of the groups (informal subtribal) "Plinia", "Myrcia" and "Myrceugenia" (sensu Lucas et al. 2007), (Tribe Myrteae, Family Myrtaceae). The leaves studied in this work are characterized by being simple, with apex and base variable, membranaceous to coriaceous in texture, and with entire margin. Its venation pattern is characterized by having the first vein category pinnate, simple, and straight, without agrophic veins; venation of secondary category with always brochidodromous-camptodromous veins, with one paramarginal vein, and may have two, one, or none intramarginal vein; the third and fourth vein category are random reticulate or branched, the areolae vary from undeveloped to fully developed and venules branching one, two, or more times.
Key words: Leaf Architecture; Myrtaceae; "Group Myrcia"; "Group Plinia"; "Group Myrceugenia"; Argentina."

"Descripción: Hojas simples, pecioladas, de 4.0-4.9 cm de largo y 1.5-2.1 cm de ancho, con lámina coriácea, simétricas, micrófilas, ovadas a elípticas; con base aguda cuneada y, ápice agudo acuminado, rostrado. Margen entero. Pecíolo normal y marginal, 5-6 de mm de largo y 1 mm de ancho. Venación de primera categoría pinnada, simple y recta; sin venas agróficas. 29- 35 pares de venas secundarias, camptódromas, broquidódromas, con vena paramarginal formada por venas de segunda categoría y, con una vena intramarginal formada por los ojales de venas de tercera categoría. Las venas de segunda categoría emergen irregularmente en ángulo agudo (70º en la base, 55º-70º en el centro y 90º en el ápice); curvadas y separadas de manera no uniforme. Áreas intercostales bien desarrolladas con ninguna, 1, 2 o 3 venas intersecundarias simples (raramente compuestas). Venación de tercera categoría reticulada al azar, de curso recto o sinuoso, las venas emergen variablemente en ángulo recto u obtuso. Venación de cuarta y quinta categoría reticulada al azar. Aréolas bien desarrolladas, con 4-5 lados y orientadas al azar. Vénulas ramificadas una o más veces. Venación de mayor orden: séptimo u octavo. Venación última marginal ojalada completa."

"Description: Simple leaves, petiolate, 4.0-4.9 cm long and 1.5-2.1 cm wide, with coriaceous lamina, symmetrical, microphilic, ovate to ellipticals; with acute cuneate base and, apex acute acuminate, rostrado. Full margin. Normal and marginal petiole, 5-6 mm long and 1 mm wide. First category pinnate, simple and straight; without agronomic veins. 29- 35 pairs of secondary veins, camptódromas, broquidódromas, with paramarginal vein formed by veins of second category and, with an intramarginal vein formed by the veins of third category veins. The second category veins emerge irregularly at an acute angle (70º at the base, 55º-70º at the center and 90º at the apex); curved and unevenly spaced. Well developed intercostal areas with none, 1, 2 or 3 simple intersecundary (rarely compound) veins. Venation of third category randomly cross-linked, straight or sinuous, the veins emerge variably at right or obtuse angle. Venation of fourth and fifth category reticulated at random. Well-developed, 4-5-sided, randomly oriented arbors. Branched veins one or more times. Venation of greater order: seventh or eighth. Venation last marginal full eye."
