Male flowers: Inflorescence without a peduncle and strictly axillary. Flowers about 3 mm diam. without a disk. Female flowers: Flowers about 1.5-2 mm diam., +/- sessile. Style +/- columnar, exserted at flowering.
Capsules about 14-lobed, concave at the apex, about 15 mm diam., resembling a miniature Queensland Blue pumpkin (Cucurbita pepo). Cotyledons cupped, much wider than the radicle.
Cotyledons about 12-13 x 8-9 mm. Hypocotyl hairy. First pair of leaves with stipules about 1 mm long. At the tenth leaf stage: leaf blade obovate, apex shortly acuminate or mucronate, base cuneate, glabrous, veins 6-9 forming loops inside the leaf blade margin. Stipules shortly triangular.
