Photo of a tree in a rainforest. Growing up the trunk is a climbing aroid. The lower leaves are shingle-like but upper leaves are larger, have long petioles, and are not shingle-shaped. Scott Zona CC BY-NC 2.0.

Another classic case of heteroblasty is Monstera dubia (#Araceae). It starts life as a shingle-leaf climber, but as it reaches the higher light levels of the canopy, the leaves enlarge & take on adult morphology. Here it’s growing in Costa Rica. #heteroblasty #Shingleleaf #botany 🌱🧪🌾
