Nepenthales (Nepenthales Bercht. & J.Presl) is an order of carnivorous flowering plants in the Cronquist system of plant classification. [1]
Nepenthales (Nepenthales Bercht. & J.Presl) is an order of carnivorous flowering plants in the Cronquist system of plant classification. [1]
The order was placed in the subclass Dilleniidae, which in the 1981 version of this system included: [1]
All three families are carnivorous plant families. The Droseraceae contains three extant genera: Drosera (sundews), which catch insects with adhesive droplets, Dionaea (Venus flytrap), which capture them in leaves with interlocking teeth, and Aldrovanda (waterwheel plant). The other two families include pitcher plants, which drown their prey.
Plant taxonomy systematists currently favor the APG IV system of 2016 over the older Cronquist system for classifying flowering plants (Angiosperms).
The 2009 APG III system assigned the first two families to the order Caryophyllales and the last family to the order Ericales. [2]
The Brassicales are an order of flowering plants, belonging to the eurosids II group of dicotyledons under the APG II system. One character common to many members of the order is the production of glucosinolate compounds. Most systems of classification have included this order, although sometimes under the name Capparales.
The Nymphaeales are an order of flowering plants, consisting of three families of aquatic plants, the Hydatellaceae, the Cabombaceae, and the Nymphaeaceae. It is one of the three orders of basal angiosperms, an early-diverging grade of flowering plants. At least 10 morphological characters unite the Nymphaeales. Molecular synapomorphies are also known.
Ceratophyllaceae is a cosmopolitan family of flowering plants including one living genus commonly found in ponds, marshes, and quiet streams in tropical and in temperate regions. It is the only extant family in the order Ceratophyllales. Species are commonly called coontails or hornworts, although hornwort is also used for unrelated plants of the division Anthocerotophyta.
Geraniales are a small order of flowering plants, included within the rosid subclade of eudicots. The largest family in the order is Geraniaceae with over 800 species. In addition, the order includes the smaller Francoaceae with about 40 species. Most Geraniales are herbaceous, but there are also shrubs and small trees.
The Aquifoliales are an order of flowering plants, including the Aquifoliaceae (holly) family, and also the Helwingiaceae and the Phyllonomaceae. In 2001, the families Stemonuraceae and Cardiopteridaceae were added to this order. This circumscription of Aquifoliales was recognized by the Angiosperm Phylogeny Group when they published the APG II system in 2003. In the Cronquist system, there is no Aquifoliales order: the Aquifoliaceae are placed within the order Celastrales and the others are in other families.
The Zygophyllales are an order of dicotyledonous plants, comprising the following two families:
Gunneraceae is a family of flowering plants, closely related to Myrothamnaceae, together forming the order Gunnerales. Such a family has been recognized by most taxonomists. Gunneraceae consists of the single genus Gunnera with 63 known species.
Petrosaviaceae is a family of flowering plants belonging to a monotypic order, Petrosaviales. Petrosaviales are monocots, and are grouped within the lilioid monocots. Petrosaviales are a very small order of photosynthetic (Japonolirion) and rare leafless achlorophyllous, mycoheterotrophic plants (Petrosavia) found in dark montane rainforests in Japan, China, Southeast Asia and Borneo. They are characterised by having bracteate racemes, pedicellate flowers, six persistent tepals, septal nectaries, three almost distinct carpels, simultaneous microsporogenesis, monosulcate pollen, and follicular fruit.
The Angiosperm Phylogeny Group (APG) is an informal international group of systematic botanists who collaborate to establish a consensus on the taxonomy of flowering plants (angiosperms) that reflects new knowledge about plant relationships discovered through phylogenetic studies.
The Xyridaceae are a family of flowering plants. This family has been recognized by many taxonomists and is known as the yellow-eyed grass family.
Plumbaginaceae is a family of flowering plants, with a cosmopolitan distribution. The family is sometimes referred to as the leadwort family or the plumbago family.
Asphodelaceae is a family of flowering plants in the order Asparagales. Such a family has been recognized by most taxonomists, but the circumscription has varied widely. In its current circumscription in the APG IV system, it includes about 40 genera and 900 known species. The type genus is Asphodelus.
Trimeniaceae is a family of flowering plants recognized by most taxonomists, at least for the past several decades. It is a small family of one genus, Trimenia, with eight known species of woody plants, bearing essential oils. The family is subtropical to tropical and found in Southeast Asia, eastern Australia and on several Pacific Islands.
Myrothamnus is a genus of flowering plants, consisting of two species of small xerophytic shrubs, in the southern parts of tropical Africa and in Madagascar. Myrothamnus is recognized as the only genus in the family Myrothamnaceae.
The Thurniaceae are a family of flowering plants composed of two genera with four species. The botanical name has been recognized by most taxonomists.
Cyclanthaceae is a family of flowering plants.
The Rapateaceae are a family of flowering plants. The botanical name has been recognized by most taxonomists.
The Muntingiaceae are a family of flowering plants, belonging to the rosid order Malvales. The family consists of three genera: Dicraspidia, Muntingia, and Neotessmannia, each with a single species. They are woody plants of the tropical regions of America. The older Cronquist system placed these genera in the family Tiliaceae, with which they share morphological similarities, but have no evolutionary affinity. Muntingia calabura is widely introduced in tropical regions, because of its edible fruit. Dicraspidia donnell-smithii and Neotessmannia uniflora are the other two species in the family, the latter only known from herbarium specimens.
The Dioncophyllaceae are a family of flowering plants consisting of three species of lianas native to the rainforests of western Africa.
Caryophyllales is a diverse and heterogeneous order of flowering plants that includes the cacti, carnations, amaranths, ice plants, beets, and many carnivorous plants. Many members are succulent, having fleshy stems or leaves. The betalain pigments are unique in plants of this order and occur in all its families with the exception of Caryophyllaceae and Molluginaceae.
