However, this conflicts with molecular analyses of combined sequences from multiple genes (beginning with Mathews & Donoghue, 1999; Parkinson et al., 1999; Qiu et al., 1999; Soltis et al., 1999; reviewed in Soltis et al., 2005), which identified Amborella, Nymphaeales, and Austrobaileyales (the "ANITA lines") as the first three branches below the vast bulk (ca.
The main plants were as follows: fluitantes as diatom, Cyanophyta, and chlorella, and so forth; floating plants as Eichhornia crassipes, Nymphaeales, Floral Aquatic, Salvinia natans, and so forth; submerged plants as Ceratophyllum demersum, Potamogeton distinctus; water woody plants as Taxodium ascendens, Metasequoia glyptostroboides, dryland willow, Pterocarya stenoptera, italian popular, and so forth; water herbage as Iris wilsonii, Typha orientalis, reed, Erigeron annuus, Indian Kalimeris Herb, Common hogfenneI root, and so forth.
Plants in one of the oldest surviving floral lineages, the water lily group known as the Nymphaeales, make endosperm, but morn contributes one nucleus, not two.
For example, non-molecular-based studies have suggested that the monocots are most closely related to the Ranales (Ranunculales, Nymphaeales, Magnoliales, Ceratophyllum et al.) (Hutchinson, 1959), the Nymphaeales (Cronquist, 1981; Takhtajan, 1969, 1980), the Ariflorae (Thorne, 1976), the Dioscoreales (Huber, 1969), early shrubby dicotyledons (Stebbins, 1974), the Dioscoreales and the Magnoliifloreae (Dahlgren and Clifford, 1982), the Melanthiales (Thorne, 1992) and the paleoherbs (Aristolochiales, Nymphaeales, Piperales) (Behnke, 1969, 1971; Loconte and Stevenson, 1991).
The inclusion of absence of cambium in monocots and a few non-monocots (Nymphaeales), may seem unexpected, but absence of a cambium is the ultimate juvenile condition.
That author denominates hydropoten as unicellular or multicellular trichomes and, based on analyses of evolutionary characters, it is affirmed that this trichome is a synapomorphy for Nymphaeales. Flydropoten are cited by Sculthorpe (1967) and Lavid et al.
The results differed, and one placed water lilies, or Nymphaeales, beside Amborella on that bottom branch.
