FIGURE 12. Arils found in the Eschweilera integrifolia clade. A. E. caudiculata (Cornejo 8106). B. E. antioquensis (Luteyn & Callejas 12025). C. E. ovalifolia (S. A. Mori photo only). A. Top left: Side view of seed showing lateral aril. Note that this type of lateral aril extends onto both ends of the seed. Top right: Rounded side of hemispherically-shaped seed. Bottom left: Lateral aril of wedge-shaped seed. Bottom right: Flat side (left) and round side (right) of hemispherically shaped seed. B. Three different views of wedge-shaped seed. C. Cross-section of seed with spreading aril. Note that the next layer is the seed coat, and the center is filled with an undifferentiated (= macropodial) embryo. Photos by S. A. Mori.
