Leucanthemum paludosum (formerly Chrysanthemum paludosum and Mauranthemum paludosum) is a perennial plant of the Asteraceae family.
The genus Bowenia includes two living and two fossil species of cycads in the family Stangeriaceae, sometimes placed in their own family Boweniaceae.
 They are entirely restricted to Australia.
 The two living species occur in Queensland.
 "B. spectabilis" grows in warm, wet, tropical rainforests, on protected slopes and near streams, primarily in the lowlands of the Wet Tropics Bioregion.
 However it has a local form with serrate pinna margins that grows in rainforest, "Acacia"-dominated transition forest and also "Casuarina"-dominated sclerophyll forest on the Atherton Tableland, where it is subject to periodic bushfire.
 "B. serrulata" grows in sclerophyll forest and transition forest close to the Tropic of Capricorn.
Leucanthemum is a genus of flowering plants in the aster family, Asteraceae.
 It is mainly distributed in southern and central Europe.
 Some species are known on other continents as introduced species, and some are cultivated as ornamental plants.
 The name "Leucanthemum" derives from the Greek words "λευκός – leukos" ("white") and "ἄνθεμον – anthemon" ("flower").
Rhodanthemum syn.
 "Chrysanthemopsis", "Pyrethropsis" (Moroccan daisy), is a genus of flowering plants in the family Asteraceae, mostly native to exposed rocky places in Northern Africa (Morocco and Algeria).
 Formerly included in either "Chrysanthemum" or "Leucanthemum", the 10 or 15 species of "Rhodanthemum" display many similarities to their former parents, with composite daisy-like flowers.
 They are mat-forming, prostrate perennials or subshrubs, and some are cultivated as ornamental plants.
Bowenia serrulata, the Byfield fern, is a cycad in the Stangeriaceae family.
 Its bipinnate fronds, arising from a subterranean caudex, give it the appearance of a fern.
 However it is not a fern as its vernacular name and appearance suggest.
 It is endemic to the vicinity of Byfield, Australia.
Leucanthemum maximum is a species of flowering plant in the aster family known by the common name max chrysanthemum.
 It is native to France and Spain but it can be found growing wild in other parts of the world as an introduced species and sometimes a garden escapee.
 It is a rhizomatous perennial herb growing 30 to 70 centimeters tall with many large serrated leaves around the base of the stem on winged petioles.
 There are smaller lance-shaped leaves alternately arranged along the stem.
 The inflorescence is generally a large, solitary flower head which may exceed 8 centimeters in diameter.
 It has a fringe of 20 to 30 white ray florets around a center of many densely packed yellow disc florets.
 The fruit is a small ribbed achene without a pappus.
Leucanthemum vulgare, the ox-eye daisy, or oxeye daisy, is a widespread flowering plant native to Europe and the temperate regions of Asia and an introduced plant to North America, Australia and New Zealand.
 It is one of a number of family Asteraceae plants to be called a "daisy", and has the additional vernacular names common daisy, dog daisy and moon daisy.
Cassida leucanthemi is a species of beetle in the leaf beetle family, that can be found in Austria, the Czech Republic, France, Italy (Liguria), Poland, and Spain.
 The host plants are Asteraceae species, including "Leucanthemum vulgare", "Carduus argemose" and "Carduus obtusisquamosus".
 It also feeds on Caryophyllaceae species, particularly "Silene nutans".
Stangeriaceae is the smallest family of cycads, both in number of living and fossil species.
 The family contains only two living genera, "Stangeria" and "Bowenia", though the latter genus has been recommended for placement in a separate family by itself.
Bowenia spectabilis is a species of cycad in the Stangeriaceae family.
 It is endemic to Queensland, Australia.
 Its natural habitat is subtropical or tropical moist lowland forests.
