Abstract The angiosperm genus Myriophyllum (Haloragaceae) is among the most species-rich genera of aquatic core-eudicots. Myriophyllum has a cosmopolitan distribution with its center of diversity in Australia (> 37 endemics). The widespread invasive species of the genus (M. aquaticum, M. heterophyllum, and M. spicatum) have drawn attention from international natural resource managers. Myriophyllum species are notoriously difficult to identify using vegetative morphology alone, which commonly… 

First record of Myriophyllum oguraense Miki (Haloragaceae) in Korea

A previously unrecorded species of Korean Myriophyllum L. oguraense Miki has been reported, regarded as a Japanese endemic for some 60 years, with characteristic turion shape.

Delimiting invasive Myriophyllum aquaticum in Kashmir Himalaya using a molecular phylogenetic approach.

A maximum parsimony tree recovered from phylogenetic analyses of the internal transcribed spacer sequences of nuclear ribosomal DNA was used to authenticate the identification of M. aquaticum for exclusive delimitation from other related species in the study region using a molecular phylogenetic approach.

Notas sobre la condición sexual de Myriophyllum aquaticum, Haloragaceae

Observations support the idea that M. aquaticum is not a strictly dioecious species, at least in Argentina, and supported by field observations.

Efficient distinction of invasive aquatic plant species from non‐invasive related species using DNA barcoding

Based on the criteria of universal application, high sequence divergence and level of species discrimination, the trnH‐psbA noncoding spacer was the best performing barcode in the aquatic plant species studied and may be helpful with enforcing a ban on trade of such invasive species.

Influence of niche similarity on hybridization between Myriophyllum sibiricum and M. spicatum

The association between hybridization pattern and climate niche similarity suggests that the level of hybridization was promoted by niche overlap, and the significance of climate niche with respect to hybridization patterns in plants is highlighted.

Phenological episodes of Myriophyllum spicatum (Haloragaceae); a highly invasive species in Kashmir Himalayan aquatic ecosystems.

In standing water populations a high seed set was observed, whereas in running waters seed formation does not take place, and in standing waters flowering phase prolongs when compared to running water populations.

Development of microsatellite markers in the hexaploid aquatic macrophyte, Myriophyllum spicatum (Haloragaceae)1

The results indicate that these markers will be significant for studies of population genetic structure and evolutionary history of M. spicatum as well as some of its related species.

Ecology and Environmental Impact of Myriophyllum heterophyllum, an Aggressive Invader in European Waterways

The submerged evergreen aquatic plant Myriophyllum heterophyllum is among the worst invasive species in Europe, causing severe problems especially in navigation channels but also lentic systems. This



Phylogenetic systematics and character evolution in the angiosperm family Haloragaceae.

There are multiple (two or three) origins of the submerged aquatic habit in the family and potentially an intermediate reversal to the terrestrial habit, neither previously demonstrated in a core eudicot family using an explicit phylogenetic hypothesis.


North American representatives of the genus Myriophyllum are aquatic plants with small flowers that provide few diagnostic characters for distinguishing species, and taxonomic problems evidently exist within the genus.

Myrophyllum (Haloragaceae) in Australasia. 2. The Australian Species.

The 36 species of Myriophyllum found in Australia are keyed, described and illustrated, and the grouping of the Australian species into 'alliances' is discussed, and their relationships with some extra- Australian species are explored.

A revision of South American Myriophyllum (Haloragaceae) and its repercussions on some Australian and North American species.

The three species of Myriophyllum occurring naturally in South America (M. aquaticum, M. quitense and M. mattogrossensis) are keyed and described, and the three previously described species of the 'elatinoides' complex is discussed, and it is suggested that two varieties should be recognized.

An annotated key to the South-East Asiatic, Malesian, Mascarene, and African species of Myriophyllum (Haloragaceae)

It is concluded that, as the species show a reticulate affinity by parallelism, especially as regards reductions in both vegetative and sexual organs, the usefulness of distinguishing infrageneric taxa is debatable and not advisable.

Geographic distribution and genotypic composition of invasive hybrid watermilfoil (Myriophyllum spicatum × M. sibiricum) populations in North America

The recent recognition of invasive hybrid watermilfoil (Myriophyllumspicatum × M. sibiricum) in North America has necessitated a more thorough evaluation of its overall distribution and occurrence in


This work has verified many of Vochting's observations in the light of today's terminology and extends the range of seasonal shoot-apical studies on Myriophyllumn heterophyllum.

A Conspectus of Myriophyllum (Haloragaceae) in North America

Eight of the common species of the genus Myriophyllum are found to exhibit sufficient phenotypic plasticity to account for most if not all the taxonomic problems encountered.

Evidence of hybridity in invasive watermilfoil (Myriophyllum) populations

Molecular data demonstrate clearly that invasive watermilfoil populations in North America have resulted from hybridization between nonindigenous and native species, and suggest that invasiveness in these aggressive aquatic weeds may be linked to heterosis maintained by vegetative propagation.
