Task: Question Generation
Input (English): Context_1 : A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place". Examples commonly are plants unwanted in human-controlled settings, such as farm fields, gardens, lawns, and parks. Taxonomically, the term "weed" has no botanical significance, because a plant that is a weed in one context is "not" a weed when growing in a situation where it "is" in fact wanted, and where one species of plant is a valuable crop plant, another species in the same genus might be a serious weed, such as a wild bramble growing among cultivated loganberries. Many plants that people widely regard as weeds also are intentionally grown in gardens and other cultivated settings, in which case they are sometimes called beneficial weeds. The term "weed" also is applied to any plant that grows or reproduces aggressively, or is invasive outside its native habitat. More broadly "weed" occasionally is applied pejoratively to species outside the plant kingdom, species that can survive in diverse environments and reproduce quickly; in this sense it has even been applied to humans. Context_2 : Harpagophytum procumbens, also called grapple plant, wood spider and most commonly devil's claw, is a genus of plants in the sesame family, native to southern Africa. Plants of the genus owe their common name "devil's claw" to the peculiar appearance of their hooked fruit. Several species of North American plants in genus "Proboscidea" and certain species of "Pisonia" are however also known by this name. Devil's claw's tuberous roots are used in folk medicine to reduce pain. Context_3 : The Deep-sea dragonfish is a member of the Stomiidae family. There are many genera and over two hundred different species altogether in the Stomiidae family. The most known about is the Barbeled Dragonfish. This dragonfish lives in the deep parts of the Atlantic Ocean beyond where any plant life grows or light reaches. This habitat has caused the Dragonfish to adapt to the conditions at these depths by having light-producing organs called photophores and skeletons that better suit deep-sea life. Context_4 : Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology. A botanist or plant scientist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word βοτάνη ("botanē") meaning "pasture", "grass", or "fodder"; βοτάνη is in turn derived from βόσκειν ("boskein"), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including ca 369,000 species of flowering plants), and ca 20,000 are bryophytes. Context_5 : Brownea is a genus of about 30 species in the family Fabaceae, subfamily Detarioideae. The genus is native to tropical regions of the Americas. The species are shrubs and trees growing to 20 m tall. Context_6 : Pisonia is a genus of flowering plants in the four o'clock flower family, Nyctaginaceae. It was named for Dutch physician and naturalist Willem Piso (1611–1678). Certain species in this genus are known as catchbirdtrees, birdcatcher trees or birdlime trees because their sticky seeds reportedly trap small birds. These sticky seeds are postulated to be an adaptation of some island species to ensure the dispersal of seeds between islands by attaching them to birds. These island species include "P. brunoniana" of Australasia and Polynesia and "P. umbellifera", which is widespread in the tropical Indo-Pacific region. Context_7 : Flora is the plant life occurring in a particular region or time, generally the naturally occurring or indigenous—native plant life. The corresponding term for animal life is fauna. "Flora", "fauna" and other forms of life such as fungi are collectively referred to as biota. Sometimes bacteria and fungi are also referred to as flora, as in the terms gut flora or skin flora. Context_8 : Mulranny (Irish: "an Mhala Raithní" , meaning "the hill-brow of the ferns" )—sometimes spelled as 'Malaranny', 'Mullaranny', 'Mullranny' or 'Mulranny'—is a seaside village on the isthmus between Clew Bay and Blacksod Bay in County Mayo, Ireland. Mulranny is the home of colourful giant Fuchsias, Ferns and exotic plants. This plant life is celebrated each summer during the Mulranny Mediterranean Heather Festival. Mulranny has been cited as a possible source of the ancient Gallowglass MacNevin family, who originally emigrated to Scotland in the mid 10th Century. The Nevin Coat of Arms has a Fern as a main symbol. Context_9 : The Phanerozoic Eon (British English Phanærozoic) is the current geologic eon in the geologic time scale, and the one during which abundant animal and plant life has existed. It covers round 5 million years to the present, and began with the Cambrian Period when diverse hard-shelled animals first appeared. Its name was derived from the Ancient Greek words φανερός (phanerós) and ζωή (zōḗ), meaning "visible life", since it was once believed that life began in the Cambrian, the first period of this eon. The time before the Phanerozoic, called the "Precambrian" supereon, is now divided into the Hadean, Archaean and Proterozoic eons. Context_10 : Pogonomyrmex occidentalis, or the western harvester ant, is a species of ant that inhabits the deserts and arid grasslands of the American West at or below 6300 ft . Like other harvester ants in the genus "Pogonomyrmex", it is so called because of its habit of collecting edible seeds and other food items. The specific epithet ""occidentalis"", meaning "of the west", refers to the fact that it is characteristic of the interior of the Western United States; its mounds of gravel, surrounded by areas denuded of plant life, are a conspicuous feature of rangeland. When numerous, they may cause such loss of grazing plants and seeds, as to constitute both a severe ecological and economic burden. They have a painful and venomous sting. fact_1 : Pisonia is a genus of flowering plants in the four o'clock flower family, Nyctaginaceae. fact_2 :  Certain species in this genus are known as catchbirdtrees, birdcatcher trees or birdlime trees because their sticky seeds reportedly trap small birds. fact_3 : Brownea is a genus of about 30 species in the family Fabaceae, subfamily Detarioideae. Answer: Pisonia
Output (English): Which genus of plant life is sometimes called a catchbirdtree, Pisonia or Brownea?
