Orontioideae is a subfamily of flowering plants in the family Araceae. The subfamily consists of three genera namely, Lysichiton (one to two species of skunk cabbage from North America and Asia), Orontium (golden club, one living species from eastern North America and two extinct species known from fossils), and Symplocarpus (several species of skunk cabbage from North America and Asia). Characteristics of Orontioideae include medium-sized pollen grains and subterranean stems. Species in the subfamily have a base chromosome number of X=13.
Brassicaceae or Cruciferae is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple, lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall.
Zingiberaceae or the ginger family is a family of flowering plants made up of about 50 genera with a total of about 1600 known species of aromatic perennial herbs with creeping horizontal or tuberous rhizomes distributed throughout tropical Africa, Asia, and the Americas. Many of the family's species are important ornamental, spice, or medicinal plants. Ornamental genera include the shell gingers (Alpinia), Siam or summer tulip, Globba, ginger lily (Hedychium), Kaempferia, torch-ginger Etlingera elatior, Renealmia, and ginger (Zingiber). Spices include ginger (Zingiber), galangal or Thai ginger, melegueta pepper, myoga, korarima, turmeric (Curcuma), and cardamom.
The Arecaceae is a family of perennial flowering plants in the monocot order Arecales. Their growth form can be climbers, shrubs, tree-like and stemless plants, all commonly known as palms. Those having a tree-like form are called palm trees. Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds, arranged at the top of an unbranched stem. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of habitat within their range, from rainforests to deserts.
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe. Also known as the arum family, members are often colloquially known as aroids. This family of 140 genera and about 4,075 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions.
Cypripedioideae is a subfamily of orchids commonly known as lady's slipper orchids, lady slipper orchids or slipper orchids. Cypripedioideae includes the genera Cypripedium, Mexipedium, Paphiopedilum, Phragmipedium and Selenipedium. They are characterised by the slipper-shaped pouches of the flowers – the pouch traps insects so they are forced to climb up past the staminode, behind which they collect or deposit pollinia, thus fertilizing the flower. There are approximately 165 species in the subfamily.
The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.
The Pieridae are a large family of butterflies with about 76 genera containing about 1,100 species, mostly from tropical Africa and tropical Asia with some varieties in the more northern regions of North America and Eurasia. Most pierid butterflies are white, yellow, or orange in coloration, often with black spots. The pigments that give the distinct coloring to these butterflies are derived from waste products in the body and are a characteristic of this family. The family was created by William John Swainson in 1820.
The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. They are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae.
Acorus is a genus of monocot flowering plants. This genus was once placed within the family Araceae (aroids), but more recent classifications place it in its own family Acoraceae and order Acorales, of which it is the sole genus of the oldest surviving line of monocots. Some older studies indicated that it was placed in a lineage, that also includes aroids (Araceae), Tofieldiaceae, and several families of aquatic monocots. However, modern phylogenetic studies demonstrate that Acorus is sister to all other monocots. Common names include calamus and sweet flag.
Hamamelidaceae, commonly referred to as the witch-hazel family, is a family of flowering plants in the order Saxifragales. The clade consists of shrubs and small trees positioned within the woody clade of the core Saxifragales. An earlier system, the Cronquist system, recognized Hamamelidaceae in the Hamamelidales order.
Nelumbo is a genus of aquatic plants with large, showy flowers. Members are commonly called lotus, though the name is also applied to various other plants and plant groups, including the unrelated genus Lotus. Members outwardly resemble those in the family Nymphaeaceae, but Nelumbo is actually very distant to that family.
Symplocarpus foetidus, commonly known as skunk cabbage or eastern skunk cabbage, is a low-growing plant that grows in wetlands and moist hill slopes of eastern North America. Bruised leaves present an odor reminiscent of skunk.
Symplocarpus is a genus of flowering plants in the family Araceae, native to United States, Canada and eastern Asia. The genus is characterized by having large leaves and deep root systems with contractile roots used for changing the plant's level with the ground. Symplocarpus species grow from a rhizome and their leaves release a foul odor when crushed.
Lysichiton is a genus in the family Araceae. These plants are known commonly as skunk cabbage or less often as swamp lantern. The spelling Lysichitum is also found. The genus has two species, one found in north-east Asia, the other in north-west America.
The Polemoniaceae are a family of flowering plants consisting of about 25 genera with 270–400 species of annuals and perennials native to the Northern Hemisphere and South America, with the center of diversity in western North America.
Thermogenic plants have the ability to raise their temperature above that of the surrounding air. Heat is generated in the mitochondria, as a secondary process of cellular respiration called thermogenesis. Alternative oxidase and uncoupling proteins similar to those found in mammals enable the process, which is still poorly understood.
Orontium aquaticum, sometimes called golden-club, floating arum, never-wets or tawkin, is a species of flowering plants in the family Araceae. It is the single living species in the genus Orontium, which also contains several extinct species described from fossils. O. aquaticum is endemic to the eastern United States and is found growing in ponds, streams, and shallow lakes. It prefers an acidic environment. The leaves are pointed and oval with a water repellent surface. The inflorescence is most notable for having an extremely small almost indistinguishable sheath surrounding the spadix. Very early in the flowering this green sheath withers away leaving only the spadix.
Pothoideae is a subfamily of flowering plants in the family Araceae. The species in the subfamily are true aroids.
Lysichiton camtschatcensis, common name Asian skunk cabbage, white skunk cabbage, Far Eastern swamp lantern or Japanese swamp lantern, is a plant found in swamps and wet woods, along streams and in other wet areas of the Kamchatka Peninsula, the Kuril Islands, Sakhalin and northern Japan. The common name "skunk cabbage" is used for the genus Lysichiton, which includes L. americanus, the western skunk cabbage, noted for its unpleasant smell. The Asian skunk cabbage is more variable: plants have been reported in different cases to smell disgusting, not at all, and sweet. In Japanese it is known as mizubashō from a supposed similarity to the Japanese banana, a name with poetic rather than malodorous associations. It is not closely related to the true cabbage.
