Belongs within: Alismatales.Contains: Typhonium, Orontioideae, Lemnaceae, Pothoideae, Monsteroideae, Aroideae. The Araceae are a family of flowering plants in which most species have the flowers reduced and clustered onto a compact spike that is in turn subtended by a large, often colourful bract. Basal aroids include the settler’s twine or boorgay Gymnostachys anceps of eastern Australia,… Continue reading Araceae


Belongs within: Lilianae.Contains: Araceae, Alismataceae, Hydrocharitaceae, Potamogetonales. The Alismatanae are a clade of monocotyledonous flowering plants supported by molecular data, many of which are aquatic or semi-aquatic. Members of the clade have extrorse anthers (releasing pollen outside the flower) and seeds with a large cotyledon. Representatives include the Tofieldiaceae, small perennials with equitant leaves, racemous… Continue reading Alismatales


Belongs within: Araceae. The Lemnaceae, duckweeds, are a cosmopolitan group of small to minute floating aquatic plants. The body of the plant is reduced to a few flattened leaf-like fronds or undivided thallus (Hillman 1961).

Belongs within: Araceae.Contains: Caladieae, Arisaema. The Aroideae are a clade of aroids with the spadix (flower-spike) divided into a male and female region, and spathe differentiated into tube and blade. Lactifers are present. Pollen is inaperturate with a thin thin ectexine, thick and spongy endexine and massive intine (Angiosperm Phylogeny Website). Notable members of the… Continue reading Aroideae

Belongs within: Potamogetonales. The Potamogetonaceae are a cosmopolitan group of aquatic herbs, often bearing a combination of narrow submerged and broader floating leaves. Members include the cosmopolitan curled pondweed Potamogeton crispus, in which leaves are entirely submerged and have more or less crimped margins (Healy & Edgar 1980). Characters (from Healy & Edgar 1980): Aquatic… Continue reading Potamogetonaceae
