FIGURE 3. A. Left, fibers from apices of leaf sheaths short, loose, separating, not joined (L. major, Davidse 27845). Right, fibers from apices of leaf sheaths short, joined into a solid, woody tip (L. pulchra, Henderson 173). B. Left, pinnae bases broad, not narrowed, without swellings (L. major, Davidse 27845). Right, pinnae bases narrowed with abaxial, distal and proximal swellings adjacent to rachis (L. pulchra, Henderson 650). C. Left, midveins prominent and raised in cross-section adaxially (L. pulchra, Pardini 68). Right, midveins scarcely raised in cross-section adaxially (L. major, Davidse 27845). D. Top left, flattened fruits, obovoid in side view, the surfaces with raised, reticulate ridges from mesocarp fibers, giving a wrinkled appearance (L. pulchra, Steyermark 102653). Top right, flattened fruits, globose in side view, the surfaces with raised, reticulate ridges from mesocarp fibers, giving a wrinkled appearance (L. pulchra, Henderson 184). Middle, non-flattened fruits, globose to ellipsoid, the surfaces with raised, reticulate ridges from mesocarp fibers, giving a wrinkled appearance (L. piassaba, Stergios 15378). Bottom left, flattened fruits, obovoid in side view, the surfaces smooth or with obscure, non-reticulate ridges from mesocarp fibers, Brazil (L. major, Fróes 22368). Bottom right, flattened fruits, obovoid in side view, the surfaces smooth or with obscure, non-reticulate ridges from mesocarp fibers, Venezuela (L. major, Davidse 27845). Scale bar = 1 cm.
