Ceratophyllum Tanaiticum
''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. ''Ceratophyllum'' grows completely submerged, usually, though not always, floating on the surface, and does not tolerate drought. The plant stems can reach 1–3 m in length. At intervals along nodes of the stem they produce rings of bright green leaves, which are narrow and often much-branched. The forked leaves are brittle and stiff to the touch in some species, softer in others. Roots are completely absent and are missing even in the embryonic stage, but sometimes they develop modified leaves with a rootlike appearance, which anchor ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ceratophyllum Submersum
''Ceratophyllum submersum'', commonly known as the soft hornwort or tropical hornwort, is a species of ''Ceratophyllum''. It is a submerged, free-floating aquatic plant. It has been reported from Europe, Central Asia, northern Africa, scattered places in tropical Africa, Turkey, Oman, Florida, and the Dominican Republic. It is similar to the submerged macrophyte ''Ceratophyllum demersum'', a congeneric plant that is found in most regions of the world. Description The ''C. submersum,'' is a free floating aquatic plant which forks from stem three to four times and ends have 6 to 8 threadlike tips. Compared to the leaves of ''C. demersum'' which fork just one to two times, ends in 3 to 4 tips, as a result the ''C. submersum'' has a more delicate look to it. The temperature tolerance is suggested to be between 4°C to 30°C, the optimal temperature is noted to be 15°C to 30°C. The height of the plant is often 6 in. -12 in. (15-30 cm) or 12 in. -18 in. (30-45 cm). Habitat '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ceratophyllum Echinatum
''Ceratophyllum echinatum'', known as prickly hornwort, spiny hornwort, or spiny coontail, is an aquatic, perennial plant found in North America. Its name comes from fruits, which have a warty surface and long spines. Spiny hornwort can be found in ponds and lakes, principally in eastern North America. It is the only species of its genus endemic to North America. ''Ceratophyllum'' comes from the Greek ''keras'', "a horn" and phyllon, "leaf", which is alluding to the stiff and narrow leaf divisions. The specific epithet ''echinatum'' comes from ''echinus'' which means sea urchin or hedgehog. Description ''Ceratophyllum echinatum'' is an aquatic herb. It does not typically have any roots with stems that are freely branching and up to in length. The leaves are submerged and they are usually in whorls of 5 to 12. Its flowers do not have any petals but have sepals (3 to 15) that are sometimes mistaken for petals. The flower is tiny, may be male or female, and contains about 12 to 1 ...

Monocots
Monocotyledons (), commonly referred to as monocots, (Lilianae ''sensu'' Chase & Reveal) are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf, or cotyledon. They constitute one of the major groups into which the flowering plants have traditionally been divided; the rest of the flowering plants have two cotyledons and are classified as dicotyledons, or dicots. Monocotyledons have almost always been recognized as a group, but with various taxonomic ranks and under several different names. The APG III system of 2009 recognises a clade called "monocots" but does not assign it to a taxonomic rank. The monocotyledons include about 60,000 species, about a quarter of all angiosperms. The largest family in this group (and in the flowering plants as a whole) by number of species are the orchids (family Orchidaceae), with more than 20,000 species. About half as many species belong to the true grasses (Poaceae), which are ec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chloranthales
Chloranthaceae is a family of flowering plants (angiosperms), the only family in the order Chloranthales. It is not closely related to any other family of flowering plants, and is among the early-diverging lineages in the angiosperms. They are woody or weakly woody plants occurring in Southeast Asia, the Pacific, Madagascar, Central and South America, and the West Indies. The family consists of four extant genera, totalling about 77 known species according to Christenhusz and Byng in 2016. Some species are used in traditional medicine. The type genus is '' Chloranthus''. The fossil record of the family, mostly represented by pollen such as ''Clavatipollenites,'' extends back to the dawn of the history of flowering plants in the Early Cretaceous, and have been found on all continents. Description Chloranthaceae are fragrant shrubs or herbaceous plants, that only produce side branches on the new growth. The stems are mostly cylindrical, with solid internodes, thickened nodes ...

Magnoliids
Magnoliids (or Magnoliidae or Magnolianae) are a clade of flowering plants. With more than 10,000 species, including magnolias, nutmeg, bay laurel, cinnamon, avocado, black pepper, tulip tree and many others, it is the third-largest group of angiosperms after the eudicots and monocots. The group is characterized by trimerous flowers, pollen with one pore, and usually branching-veined leaves. Some members of the subclass are among the earliest angiosperms and share anatomical similarities with gymnosperms like stamens that resemble the male cone scales of conifers and carpels found on the long flowering axis. Classification "Magnoliidae" is the botanical name of a subclass, and "magnoliids" is an informal name that does not conform to the International Code of Nomenclature for algae, fungi, and plants. The circumscription of a subclass will vary with the taxonomic system being used. The only requirement is that it must include the family Magnoliaceae. The informal name "magnoliids ...

Austrobaileyales
Austrobaileyales is an order of flowering plants consisting of about 100 species of woody plants growing as trees, shrubs and lianas. The best-known species is ''Illicium verum'', commonly known as star anise. The order belongs to the group of basal angiosperms, the ANA grade (Amborellales, Nymphaeales, and Austrobaileyales), which diverged earlier from the remaining flowering plants. Austrobaileyales is sister to all remaining extant angiosperms outside the ANA grade.Insights into the dynamics of genome size and chromosome evolution in the early diverging angiosperm lineage Nymphaeales (water lilies), Jaume Pellicer, Laura J Kelly, Carlos Magdalena, Ilia Leitch, 2013, Genome, 10.1139/gen-2013-0039 The order includes just three families of flowering plants, the Austrobaileyaceae, a monotypic family containing the sole genus, ''Austrobaileya scandens'', a woody liana, the Schisandraceae, a family of trees, shrubs, or lianas containing essential oils, and the Trimeniaceae, essentia ...
