From the Wikipedia article [0] linked by the GP:
> Ernesto Gianoli said "Boquila's leaves are extraordinarily diverse. The biggest ones can be 10 times bigger than the smallest, and they can vary from very light to very dark. In around three-quarters of cases, they are similar to the closest leaf from another tree, matching it in size, area, length of stalk, angle, and color. Boquila's leaves can even grow a spiny tip when, and only when, it climbs onto a shrub with spine-tipped leaves."[5]
> When there are no nearby host leaves to influence them, the normal leaves of B. trifoliolata are relatively short and light green with rounded edges.[6]
Also should have let the plant grow without any mimic leaves and with an actually growing plant.
