From Wikipedia:
“In a 2022 paper, it was suggested that the plant has some sort of vision using ocelli. This hypothesis was presented on the basis of experiments in which the vine appeared to mimic plastic vines and artificial plants. However, the only control used was the lower leaves on the same plants, with an opaque shelf over them which could have influenced light exposure. The lack of control plants climbing anything apart from the same model of artificial host plant makes it plausible that the observed differences were due to age and light exposure.”
