The cotyledon leaves are a dull green with no visible nerves or markings. Transversely elliptic in shape, they measure 8 to 13 mm long by 12 to 18 mm wide and range from convex to concave. The pointed spreading auricles are 1.5 mm long. The cotyledon leaves sit atop the stout hypocotyl, which is green and smooth. The seedling leaves are crowded above the cotyledons. Resembling those of "B. coccinea", they are lined with triangular lobes or "teeth" (with a u- or v-shaped sinus) and obovate to broadly lanceolate in shape. The first set of leaves measure in length and around in width, with three or four lobes in each margin. Both upper and lower seedling leaf surfaces are covered in spreading hairs, as is the seedling stem. Juvenile leaves are obovate to truncate or mucronate with triangular lobes and measure long by wide. These lobes are smaller toward the petiole and apex of the leaf.
