Sea Randia; Zebra Wood
Occasionally grows into a tree but usually flowers and fruits as a shrub about 2-5 m tall.
Leaf blades usually rather large, about 10-23 x 10-17 cm. Petioles about 1.8-3.5 cm long. Stipules very broadly lanceolate, about 10-20 mm long, +/- longitudinally veined. Petioles clothed in pale coloured hairs. Twigs marked by numerous pale coloured lenticels.
Flowers usually strongly perfumed. Peduncles about 5-10 cm long but individual flowers sessile. Calyx about 5-6 mm long, pubescent on the outer surface, often with a solitary lobe. Corolla tube about 17-35 mm long, throat (i.e. inner surface near apex) hairy, lobes about 10-15 mm long. Anthers about 2-3.5 mm long, sessile.
Fruits sessile, +/- globose, about 15-25 mm diam., surface smooth, pericarp fibrous. Seeds about 4-6 per individual fruit. Cotyledons very short, not exceeding the diameter of the radicle and certainly much shorter.
Cotyledons obovate or spathulate, sessile, about 4-6 x 1.5-2 mm, stipulate. Stipules about 2 mm long. Hypocotyl long and slender. First pair of leaves pubescent, opposite, stipulate. At the tenth leaf stage: leaf blade +/- lanceolate, about 5.5-6.5 x 2-3 cm, pubescent on both the upper and lower surfaces, stipules large, about 9-10 mm long, broadly lanceolate, hairy on the outer surface and +/- longitudinally veined. Petiole about 1 cm long. Seed germination time 53 to 607 days.
