There is a distinct midvein, spreading lateral veins and a marginal vein separated from the margin. The stalked flower buds are arranged in umbels of between 4 and 8, each bud with a narrow, conical cap 5-9 mm (0.2-0.4 in) long. The flowers 1-2 cm (0.4-0.8 in) in diameter, with many white stamens and bloom in spring and early summer. The fruit are spherical to barrel-shaped, and 9-20 mm (0.4-0.8 in) long and broad.
