(2)Godmania aesculifolia (fig. 5, E) seed proper is circular, 7-9 mm in diameter. A conspicuously tapered wing, ca. 1 cm wide and ca. 5 cm long, flows from one side of the seed proper and tapers at the end. This almost transparent, uniseriate wing is composed entirely of nonornamented elongate cells with a slightly thickened primary or secondary wall and rounded to flattened end walls (fig. 3B). Circles on the wing (fig. 5, E) are imprints of closely appressed adjacent seeds in the fruit [no means of external attachment]
