Each flower, borne on a slim, green stem has a tiny calyx and six long, narrow, wavy petals arranged in two sets of three. Leaf Details Leaves simple, alternate, narrow lanceolate or linear lanceolate, base slightly acute or cuneate, margin wavy or undulate, apex long acuminate, membranous, coriaceous, faintly aromatic, shining dark green, glabrous above, paler glaucous beneath.
