The leaves are arranged alternately along the branches and are linear to lance-shaped, mostly long, wide, slightly sticky, have a distinct mid-vein on the lower surface and often have a hooked tip. The flowers are borne in groups of 2 or 3 in leaf axils on glabrous, sticky stalks long. There are 5 white to cream-coloured, sometimes pinkish
sepals which are lance-shaped with a rounded end and mostly long. The
petals are long and joined at their lower end to form a tube. The petal tube is usually white or cream-coloured, sometimes pale pink and has spots inside the tube. The petal tube is mostly glabrous except for the inside of the tube which is filled with long soft hairs. Two of the
stamens are fully enclosed in the tube while the other two sometimes extend slightly past its end.
