Ontogeny of stomata in some Nymphaeaceae

Proceedings of the Indian Academy of Sciences - Section A Part 3 Mathematical Sciences, 1980
In all the three species studied stomata are mostly confined to the upper epidermis but a few occur on the lower surface as well. Development is of the perigenous type. The reduction in number of cell divisions in and around the stomata in parasitic and aquatic plants is discussed.

Intergeneric Relationships within the Early-Diverging Angiosperm Family Nymphaeaceae Based on Chloroplast Phylogenomics

open access: yesInternational Journal of Molecular Sciences, 2018
The order Nymphaeales, consisting of three families with a record of eight genera, has gained significant interest from botanists, probably due to its position as a basal angiosperm. The phylogenetic relationships within the order have been well studied;

Why the monophyly of Nymphaeaceae currently remains indeterminate: an assessment based on gene-wise plastid phylogenomics

open access: yesPlant Systematics and Evolution, 2019
<p>The monophyly of Nymphaeaceae (water lilies) represents an important, but controversial aspect in the effort to understand the evolutionary history of early-diverging angiosperms. Resolving the phylogenetic position of the genus Nuphar

Disentangling historical signal and pollinator selection on the micromorphology of flowers: an example from the floral epidermis of the Nymphaeaceae [PDF]

open access: yesPlant Biology, 2018
The family Nymphaeaceae includes most of the diversity among the ANA‐grade angiosperms. Among the species of this family, floral structures and pollination strategies are quite varied.

Seedlings of Nymphaeaceae

Botanical Journal of the Linnean Society, 1975
Seedlings of Nymphaea coerulea, N. lotus and Nuphar luteum were examined for monocoty-ledonous and dicotyledonous characters. The cotyledonary formation could be interpreted either as a single bilobed structure or as two separate cotyledons. However, the presence of an operculum and the recognition of a coleoptile and mesocotyl similar to those of ...

A synopsis of Thai Nymphaeaceae

Nordic Journal of Botany, 2009
A synopsis of Nymphaeaceae from Thailand was made by means of a literature search, consultation of herbarium specimens in several Thai and European herbaria, and a survey of 47 wetlands throughout Thailand. Nymphaeaceae phylogeny, habitats and reproductive ecology are reviewed.

Vessel origins in Nymphaeaceae: Euryale and Victoria

Botanical Journal of the Linnean Society, 1995
Metaxylem tracheary elements of roots have differentiation between end walls and lateral walls in both Euryale and Victoria . End walls have narrower, more closely spaced bars and scalariform plates. Primary walls of end walls (and, to a lesser extent, lateral walls) have striations that are thickened primary wall portions orientated in an axial ...

Alkaloids of Nelumbo lutea (Willd.) pers. (Nymphaeaceae)

Journal of Pharmaceutical Sciences, 1977
A phytochemical investigation of an alcoholic extract of the petioles of Nelumbo lutea resulted in the identification of the alkaloids N-methylasimilobine, anonaine, and roemerine. The alkaloids nuciferine, armepavine, N-nornuciferine, and N-norarmepavine, previously previously reported in the whole plant, were also identified.
