"Edelweiss" is a show tune from the 1959 Rodgers and Hammerstein musical "The Sound of Music".
 It is named after the edelweiss, a white flower found high in the Alps "(Leontopodium alpinum)".
 It was created for the 1959 Broadway production of "The Sound of Music" in the role originated by performer Theodore Bikel as a song for the character of Captain Georg Ludwig von Trapp.
 In the musical, Captain von Trapp and his family sing this song during the concert near the end of Act II as a statement of Austrian patriotism in the face of the pressure put upon him to join the navy of Nazi Germany following the Anschluss.
 It is also Captain von Trapp's subliminal goodbye to his beloved homeland, using the flower as a symbol of his loyalty to Austria.
 In the 1965 film adaptation, the song is also sung by the Captain earlier in the film when he rediscovers music with his children.
Molluginaceae are a family of flowering plants recognized by several taxonomists.
 It was previously included in the larger family Aizoaceae.
 The APG III system of 2009 made no change in the status of the family as compared to the APG II system of 2003 and the APG system of 1998, apart from a reassignment of several genera, such as the placement of "Corrigiola" and "Telephium" into Caryophyllaceae, "Corbichonia" in Lophiocarpaceae, "Microtea" into Microteaceae and "Limeum" in Limeaceae, because the family was found to be widely polyphyletic in Caryophyllales.
 In addition "Macarthuria" was found not to be related to "Limeum" as previously thought and thus it was placed in Macarthuriaceae, and similarly species formerly placed in "Hypertelis", apart from type species "Hypertelis spergulacea", a true Molluginaceae, were found to belong elsewhere and were described as "Kewa" in the family Kewaceae, named for the Royal Botanic Gardens Kew.
 Molluginaceae is still assigned to the order Caryophyllales in the clade core eudicots, although the generic circumscription is difficult because "Mollugo" is not monophyletic.
Ariopsis is a genus of flowering plants in the family Araceae.
 There are only two species of plants in the genus namely "Ariopsis peltata" and "Ariopsis protanthera".
 Both species are found in the understories of tropical forests, but they both live in different areas. "
Ariopsis peltata" is found in the Western Ghats, whereas "Ariopsis protanthera" is found in Nepal, Bhutan, Assam, northern Bangladesh, Myanmar and Thailand.
 "Ariopsis" has heart shaped leaves and are tuberous plants.
 The spadix is cylindrical and has cavities into which the pollen falls into.
The Rhizobiaceae is a family of proteobacteria comprising multiple subgroups that enhance and hinder plant development.
 Some bacteria's found in the family are used for plant nutrition and collectively make up the rhizobia.
 Consequently, other bacteria's such as "Agrobacterium tumefaciens" and "A. rhizogenes" severely alter the development of plants in their ability to induce crown galls or hairy roots found on the stem.
 The family has been of an interest to scientists for centuries in their ability to associate with plants and modify plant development.
 The Rhizobiaceae are, like all Proteobacteria, Gram-negative.
 They are aerobic, and the cells are usually rod-shaped.
 Many species of the Rhizobiaceae are diazotrophs which are able to fix nitrogen and are symbiotic with plant roots.
Leontopodium is a genus of plants in the Asteraceae family (which also includes daisies and sunflowers).
 The genus is native to Europe and Asia.
 The fuzzy and somewhat stocky "petals" (technically, bracts) could be thought of as somewhat resembling lions' paws —hence the genus name combining "léōn" (lion) and "pódion" (foot).
Veratridine is a steroid-derived alkaloid from plants in the Liliaceae family that functions as a neurotoxin by abolishing inactivation of sodium ion channels.
 It is primarily obtained from the herb "Veratrum" and sabadilla seeds.
 It binds to intramembrane receptor site 2 and increases intracellular Ca concentration.
 It acts by preferentially binding to activated Na channels causing persistent activation that leads to increased nerve excitability.
The Rafflesiaceae are a family of rare parasitic plants found in the tropical forests of east and southeast Asia, including "Rafflesia arnoldii", which has the largest flowers of all plants.
 The plants are endoparasites of vines in the genus "Tetrastigma" (Vitaceae) and lack stems, leaves, roots, and any photosynthetic tissue.
 They rely entirely on their host plants for both water and nutrients, and only then emerge as flowers from the roots or lower stems of the host plants.
The Balanophoraceae (from the inflorescence which appears to be covered by barnacles) are a subtropical to tropical family of obligate parasitic flowering plants, notable for their unusual development and obscure affinities.
 The family consist of 17 genera and around 44 known species.
 The plants are normally found in moist inland forests growing on tree roots and have an aboveground inflorescence with the overall appearance of a fungus, composed of numerous minute flowers.
 The inflorescences develop inside the tuberous underground part of the plant, before rupturing it and surfacing.
 The plants are monoecious, or dioecious, and the fruits are indehiscent drupes or nuts.
 The underground portion, which attaches itself to the host, looks like a tuber, and is not a proper root system.
 The plants contain no chlorophyll.
 "Balanophora" means "bearing an acorn" (shape of the female inflorescence).
Veratrum is a genus of flowering plants in the family Melanthiaceae.
 It occurs in damp habitats across much of temperate and subarctic Europe, Asia, and North America.
Aceria clianthi is a species of mite belonging to the family Eriophyidae.
 It is found only in New Zealand.
 It is notable for being host specific to threatened plants of the genus "Clianthus".
 It is classified by Buckley "et al." as "nationally critical" under the New Zealand Threat Classification System.
 They stated ""Aceria clianthi" (Eriophyidae), has been recorded only from kakabeak ("Clianthus" spp.)
 in cultivation and once on "Lotus cornalatus" ["Lotus corniculatus"] (Fabaceae), an introduced plant growing near kakabeak (Martin 2009).
 It is given the same threat classification as kakabeak (de Lange et al. 2009)."
 Heenan had earlier stated that "the two species [of "Clianthus"] are considered to be threatened, with "C. maximus" having a rank of vulnerable, whereas "C. puniceus" is critically endangered", but the conservation status of "C. maximus" was subsequently found to be more serious.
 These threat classifications for "Clianthus" apply to plants in the wild, but the species are widely cultivated.
 "Aceria clianthi" occurs on both plants in the wild and in cultivation.
