ABSTRACT
This article has as an objective establishing the structure of the vegetative organs at Syngonium podophyllum. The structure is specific for herbaceous monocotyledonous: root has a primary structure, the stem primary structure is an intermediary form between an aerial stem and a rhizome (the presence in a fundamental parenchyma of the colaterally closed vascular bundles and the leptocentric ones). The leaf petiole has the suberified epidermis. It is characterised by the colaterally closed vascular bundles disposed peripherically and extremely well protected by the sclerenchyma and in the centre of the petiole, in the fundamental parenchyma, the same type of fascicles are placed. The middrib has a structure similar to that of the petiole. The leaf mesophyll is homogenous. The parenchyma of aerial vegetative organs of this species is crossed by aeripherous channels and their cells contain calcium oxalate crystals. The leaf is amphistomatic, the stomatic complexes are an amarilidaceous type, tetracitic or hexacitic.
