Abstract:
... In most species of the Genlisea-Utricularia sister lineage, the organs arising directly after germination comprise a single leaf-like structure, followed by a bladder-trap/stolon, with the lack of an embryonic primary root considered a synapomorphic character. Previous anatomical work suggests that the most common recent ancestor of Utricularia possessed an embryo comprising storage tissue and a m ...

Abstract:
... Beginning with light microscopy studies in the late 19th century, the placental “nutritive tissue” in carnivorous plants of Utricularia spp. has been well described by several authors. Based on observations of direct contact between the embryo sac and the “nutritive tissue” and the lack of vascularization of the ovule, it has been suggested that this nutritive tissue plays a key role in the nutrit ...
