(1) The ventral and posterior margins form an acute angle of 70u00b0, which offers an acuminate aspect.(2) In place of these, we analyzed timing of anthesis, presence or absence of seed wings and pistillate racemes, and prevalence of acuminate leaf apices and attenuate leaf bases.(3) Both the anterior and posterior rims of the pleurocoel are rounded rather than angular or acuminate .(4) The radicle and plumule form a small subglobose unit, the embryonic axis, whose acuminate lower end extends into the micropyle.(5) The orbicular-shaped mutant leaves are further characterized by the leaf apex, which is retuse in contrast to the acuminate apex of leaves of wild-type plants.
