Apical Dichotomy Demonstrated in the Angiosperm Flagellaria

Abstract

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.
