An equal dichotomy of an angiosperm vegetative apex, previously suspected on morphological grounds, is demonstrated both externally in whole apices and in histological preparations. Dichotomy is a normal developmental feature with complete continuity in growth from the simple to the bifurcated state. The accessibility of this rare phenomenon in this plant makes further, possibly experimental, approaches feasible.
