1. Numerous lanceolate leaves with basally connate, lanceolate stipules, scale leaves with stipule lobes, and scale leaves without stipule lobes form sequentially on the distal portion of the branch which eventually aborts and abscises.

2. The extrafloral nectary consists of numerous secretory and nonsecretory trichomes aggregated on the abaxial surface of each stipule.

3. Despite this plasticity, the Bracteole positioned between the tendril and the stipule is always the most developed organ (Fig

4.
