Alatocaul
Definition
Having a winged stem or a stem provided with thin, green, wing-like lateral membranous extensions; structurally characterized by the extension of the petiole or the leaf base along the main axis of the stem, forming widened ridges. In systematic and descriptive botany, this term qualifies plant species (such as certain bryophytes or angiosperms in the Asteraceae family) whose stems possess prominent geometric profiles that increase the photosynthetic surface and ensure water guidance.
