First pair of leaves broadly lanceolate, about 12-18 x 6-9 cm, glabrous, pulvinus obvious at the petiole-leaf blade junction. At the tenth leaf stage: leaves and petioles +/- glabrous when fully developed, leaflet blades shortly stalked and lacking pulvini; small oil dots just visible with a lens. Terminal bud clothed in short, pale +/- prostrate hairs. Freshly broken or crushed roots emit an odour like that of garlic (Allium sativum) or onions. Seed germination time 33 to 91 days.
