Development, Diversity and Dynamics of Plant Architecture in Utricularia subgenus Polypompholyx – Towards Understanding Evolutionary Processes in the Lentibulariaceae

Abstract To uncover the nature of various kinds stolons Utricularia subgenus Polypompholyx (Lentibulariaceae) we studied branching by scanning electron microscopy, statistically investigated correlations stolon types and other traits across 56 species, evaluated seedling development process morphological aspects. Some results were compared to sister genera Pinguicula Genlisea . A key nine in is provided. Predominant rhizoids, runner with rhizoids on nodes, without nodes but bladders internodes. Stolon taxonomically relevant correlated distribution/climate. They obviously diverged speciation events Australia. Examined seedlings showed similar developmental patterns. Stolons homologous traps leaves. Selected subterranean organs contained specific combinations roots, shoots and/or We assume - ancestor trap included processes a root leaf.
