Nymphaeaceae is a family of flowering plants, commonly called water lilies. They live as rhizomatous aquatic herbs in temperate and tropical climates around the world. The family contains five genera with about 70 known species. Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on or emergent from the surface. Leaves are round, with a radial notch in Nymphaea and Nuphar, but fully circular in Victoria and Euryale. It is the national flower of Bangladesh.
Ranunculaceae is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide.
Ceratophyllum is a cosmopolitan genus of flowering plants including four accepted living species in 2016, commonly found in ponds, marshes, and quiet streams in tropical and in temperate regions. It is the only extant genus in the family Ceratophyllaceae, itself the only extant family in the order Ceratophyllales. They are usually called coontails or hornworts, although hornwort is also used for unrelated plants of the division Anthocerotophyta.
Caltha palustris, known as marsh-marigold and kingcup, is a small to medium size perennial herbaceous plant of the buttercup family, native to marshes, fens, ditches and wet woodland in temperate regions of the Northern Hemisphere. It flowers between April and August, dependent on altitude and latitude, but occasional flowers may occur at other times.
The water-plantains (Alismataceae) are a family of flowering plants, comprising 19 genera and between 85 and 95 species. The family has a cosmopolitan distribution, with the greatest number of species in temperate regions of the Northern Hemisphere. Most of the species are herbaceous aquatic plants growing in marshes and ponds.
Austrobaileya is the sole genus consisting of a single species that constitutes the entire flowering plant family Austrobaileyaceae. The species Austrobaileya scandens grows naturally only in the Wet Tropics rainforests of northeastern Queensland, Australia.
Griselinia is a genus of seven species of shrubs and trees, with a highly disjunct distribution native to New Zealand and South America. It is a classic example of the Antarctic flora. It is the sole genus in the family Griseliniaceae; in the past it was often placed in Cornaceae but differs from that in many features.
Andromeda polifolia, common name bog-rosemary, is a species of flowering plant in the heath family Ericaceae, native to northern parts of the Northern Hemisphere. It is the only member of the genus Andromeda, and is only found in bogs in cold peat-accumulating areas.
Coriaria is the sole genus in the family Coriariaceae, which was described by Linnaeus in 1753. It includes 14 species of small trees, shrubs and subshrubs, with a widespread but disjunct distribution across warm temperate regions of the world, occurring as far apart as the Mediterranean region, southern and eastern Asia, New Zealand, the Pacific Ocean islands, and Central and South America.
Parnassiaceae Gray were a family of flowering plants in the eudicot order Celastrales. The family is not recognized in the APG III system of plant classification. When that system was published in 2009, Parnassiaceae were treated as subfamily Parnassioideae of an expanded family Celastraceae.
Calla is a genus of flowering plant in the family Araceae, containing the single species Calla palustris.
Juncaginaceae is a family of flowering plants, recognized by most taxonomists for the past few decades. It is also known as the arrowgrass family. It includes 3 genera with a total of 34 known species.
Trochodendraceae is the only family of flowering plants in the order Trochodendrales. It comprises two extant genera, each with a single species along with up to five additional extinct genera and a number of extinct species. The living species are native to south east Asia. The two living species both have secondary xylem without vessel elements, which is quite rare in angiosperms. As the vessel-free wood suggests primitiveness, these two species have attracted much taxonomic attention.
Euptelea is a genus of two species of flowering plants in the monogeneric family Eupteleaceae. The genus is found from Assam east through China to Japan, and consists of shrubs or small trees:
Crossosomataceae is a small plant family, consisting of four genera of shrubs found only in the dry parts of the American southwest and Mexico. This family has included up to ten species in the past, although as of 2021 six species are still recognised. Crossosoma are shrub-like plants which can vary from being 50 cm to 5 meters tall, with small alternating leaves that surround the stem, or leaves clustered in small spurts (fascicles). Apacheria, however, has opposite leaves. Crossosoma has usually white flowers that are generally bisexual and have 5 petals attached to a nectary disk, but in Velascoa the flowers are campanulate and have an extremely reduced nectary disk.
Grevillea acanthifolia, commonly known as the Acanthus-leaved grevillea, is a plant in the family Proteaceae and is endemic to New South Wales. It is a shrub with stiff, prickly, divided leaves and pink to purple "toothbrush" flowers.
Epipactis palustris, the marsh helleborine, is a species of orchid native to Europe and Asia.
Fouquieria is a genus of 11 species of desert plants, the sole genus in the family Fouquieriaceae. The genus includes the ocotillo and the Boojum tree or cirio. They have semisucculent stems with thinner spikes projecting from them, with leaves on the bases spikes. They are unrelated to cacti and do not look much like them; their stems are proportionately thinner than cactus stems and their leaves are larger.
Lysimachia clethroides, the gooseneck loosestrife, is a species of flowering plant, traditionally classified in the family Primulaceae. It was transferred to the family Myrsinaceae based on a molecular phylogenetic study, but this family was later merged into the Primulaceae.
Trichophorum cespitosum, commonly known as deergrass or tufted bulrush, is a species of flowering plant in the sedge family. It was originally described by the Swedish naturalist Carl Linnaeus in 1753 as Scirpus cespitosus, but was transferred to the genus Trichophorum by the Swedish botanist Carl Johan Hartman in 1849, becoming Trichophorum cespitosum.
