Lamina narrow elliptic, margin with minute serrations that are generally visible only with magnification. Primary venation pinnate. Secondary venation festooned brochidodromous; secondary veins numerous, closely spaced, moderate to broad acute; brochidodromous junction formed by secondary veins of equal thickness, with the superadjacent vein deflected apically; each secondary vein forming an apically arching series of excostal loops. Tertiary veins admedially oriented.
