In all species a leaf trace typically diverges from a continuing axial bundle before departing to a leaf, with the possible exception of Heteropsis. However, within this common organizational scheme a considerable range of variation exists, e.g., with respect to degree of branching of axial bundles, and distance from a leaf-trace branch to the point of leaf-trace departure to a leaf. In addition, we have found a wide variety of patterns of bud-trace organization in different genera of the Pothoideae. For example, prominent arcs composed of numerous bud traces occur in the central cylinder of Pothos, Pothoidium, and Heteropsis. Comparative anatomy leads to the conclusion that Pothos and Pothoidium more closely resemble Heteropsis than Anadendrum. Anadendrum should be dissociated from the tribe Pothoeae. With respect to other genera in the Pothoideae, our preliminary results suggest that each of the genera Anthurium, Culcasia, Zamioculcas, Acorus, and Gymnostuchys are highly distinct from each other.
