These are scale insect galls seen on the adaxial side of the leaf . The broad-based conical outgrowths are female galls. There were two of these, one at the base of the leaf base and another along the main vein. the gall was purplish and had a ring near the base. One of the galls showed two openings and the other a single smooth circular orifice. Also on the leaf surface were many upright tubular structures with apical openings with crenulated margins. These were male galls and they were tinged red.
