Abstract The cosmopolitan genus Nymphoides contains approximately 50 species that vary considerably in growth habit, inflorescence architecture, and in vegetative, floral, and seed morphology We undertook a phylogenetic study of 31 Nymphoides species, including all species native to Australia, to evaluate interspecific relationships and to infer the evolution of heterostyly and inflorescence architecture. Phylogenetic analysis of morphological data resolved several clades of species, but with… 
Evidence for Allopolyploid Speciation in Nymphoides (Menyanthaceae)
TLDR
DNA sequence data from two nuclear loci, phytoene desaturase (PDS) and transmembrane nine (TMN1), as well as the plastid trnT—trnF region support a scenario in which three groups of species descended from allopolyploidization events.
Phylogenetics and seed morphology of African Nymphoides (Menyanthaceae)
TLDR
Results presented here support prior hypotheses that allopolyploid species in the Americas may have originated from one or more parental lineages in Africa, particularly for herbarium specimens lacking observable floral characters.
Reticulate Evolution in Elatine L. (Elatinaceae), a Predominantly Autogamous Genus of Aquatic Plants
TLDR
An additional phylogenetic analysis of Elatine found that both polyploids probably are allopolyploids, in a pattern consistent with the placement of the putative parental taxa in previous phylogenetic analyses of ITS, matK/trnK, and rbcL sequence data.
Systematics of the Cosmopolitan Aquatic Genus Elatine
TLDR
A phylogenetic study of nearly all of the currently recognized species of Elatine using both morphological and molecular data has helped to clarify the infrageneric classification of the genus and to provide a better understanding of the natural and nonindigenous distributions of the species.
Nymphoides grayana (Menyanthaceae) in Florida verified by DNA and morphological data1
TLDR
It is concluded that the Florida specimens arrived via a natural range expansion because of the proximity of native N. grayana populations and the absence of this species in the water garden trade, and that the white and yellow floral color variants attributed to N. indica actually represent separate species.
Independent Origins of Aquatic Eupatorieae (Asteraceae)
TLDR
It is determined that submersed aquatics evolved independently in two subtribes, Adenostemmatinae (Gymnocoronis) and Trichocoroninaes (Sclerolepis and Shinnersia) and that the aquatic lineages evolved in allopatry.
Hybridization and systematics of dioecious North American Nymphoides (N. aquatica and N. cordata; Menyanthaceae)
Tiny Plants with Enormous Potential: Phylogeny and Evolution of Duckweeds
TLDR
The biogeography of Lemnaceae indicates that numerous dispersal events have occurred in relatively recent evolutionary time, and that several species essentially are cosmopolitan.
Evolutionary history of the buildup and breakdown of the heterostylous syndrome in Plumbaginaceae.
TLDR
Character state reconstructions indicated that reciprocal herkogamy evolved at least three times and that shifts to selfing and apomixis occurred on multiple occasions, providing comparative support for the early ideas of H. G. Baker on evolutionary pathways in Plumbaginaceae and the more recent selfing avoidance model.

Generic Circumscription in Menyanthaceae: A Phylogenetic Evaluation
TLDR
A phylogenetic analysis of Menyanthaceae indicates that the genera Menyanthes, Nephrophyllidium, and Nymphoides should be retained as circumscribed, with the exception that NymphOides exigua should be restored to Villarsia.
Evidence for the hybrid origin of Nymphoides montana Aston (Menyanthaceae)
TLDR
Results indicate a hybrid origin for N. montana, which subsequently retains evidence of its maternal lineage in the chloroplast genome, whereas nuclear DNA markers have been converted to resemble the paternal lineage exclusively.
Systematics of Vallisneria (Hydrocharitaceae)
TLDR
Morphology, species delimitation, and interspecific relationships were evaluated in a phylogenetic context in the aquatic monocotyledon genus Vallisneria using a combination of morphological and molecular data, and the presence of the Old World V. spiralis in Texas is conclusively documented, which constitutes the first authentic record of this nonindigenous species in North America.

TLDR
The range of structural diversity that occurs among the species of Lithospermum suggests the potential utility of this genus as a model for integrative studies of evolution, development, and molecular biology.
Phylogenetic reconstruction of the evolution of stylar polymorphisms in Narcissus (Amaryllidaceae).
TLDR
Concentrated-changes tests indicate that a long, narrow floral tube may have been associated with the emergence of stigma-height dimorphism and that this type of tube, in combination with a deep corona, likely promoted, or at least was associated with, the parallel origins of heterostyly.
Hybridization in Hydrophiles: Natural Interspecific Hybrids in Najas (Hydrocharitaceae)
TLDR
The first instance of interspecific hybridization in Najas is document using genetic evidence from three populations that were identifiable as N. guadalupensis but yielded polymorphic DNA sequence profiles, confirming their hybrid origin.
Incongruence between cpDNA and nrITS trees indicates extensive hybridization within Eupersicaria (Polygonaceae).
TLDR
Repeated allotetraploidy (as distinct from radiation at the tetraploids level) now appears to be the key mechanism governing the diversification of this taxonomically challenging group.
EVOLUTIONARY HISTORY OF THE MATING SYSTEM IN AMSINCKIA (BORAGINACEAE)
TLDR
The results of the phylogenetic analysis support the hypothesis that the self‐fertilizing taxa of the annual plant genus Amsinckia are of recent origin from outcrossing relatives.
Transfer of Villarsia cambodiana to Nymphoides (Menyanthaceae)
TLDR
It is observed that leaf and inflorescence characters associated with an erect habit, which superficially would assign V. cambodiana to Villarsia, have arisen or been lost independently in several other Menyanthaceae species representing three genera, and several characteristics of this taxon are more consistent with those of Nymphoides than ofVillarsia.
RECONSTRUCTION OF THE EVOLUTION OF REPRODUCTIVE CHARACTERS IN PONTEDERIACEAE USING PHYLOGENETIC EVIDENCE FROM CHLOROPLAST DNA RESTRICTION‐SITE VARIATION
TLDR
The results indicate that the class of optimization scheme used was the most critical factor in reconstructing character evolution, and several broad conclusions were possible when an unordered, unequally‐weighted optimization scheme was used.
