Oplismenus is a small genus of annual or perennial grasses, commonly known as basketgrass, found throughout the tropics, subtropics, and in some cases, temperate regions of the Americas, Africa, Asia, and Australia.
 The systematics of the genus are unclear, with over 100 described species, only 7 species are officially recognized as of October 2015.
Pleione praecox is a species of orchid found from the west-central Himalaya to China (southern Yunnan).
 It is the type species of the genus "Pleione".
Pleione formosana (Taiwan pleione or windowsill orchid) is a species of flowering plant in the Orchidaceae family, native to southeastern China as well as northern and central Taiwan.
 It is a deciduous perennial, terrestrial orchid growing to 15 cm tall by 30 cm wide, with spherical pseudobulbs that produce a single folded leaf.
 The pink flowers, borne in spring, have fringed white lips that are strongly marked and mottled with brown on the inner surface.
Betanodavirus or nervous necrosis virus (NNV) is a viral genus classified in the family Nodaviridae.
 It contains four recognized species: "Barfin flounder nervous necrosis virus" (BFNNV), "Redspotted grouper nervous necrosis virus"(RGNNV), "Striped Jack nervous necrosis virus" (SJNNV) and "Tiger puffer nervous necrosis virus" (TPNNV), SJNNV being the type species.
 There are other 12 tentative species in the genus that haven't been recognized by the ICTV.
 Betanodaviruses cause a disease in fish called viral nervous necrosis (VNN) or viral encephalopathy and retinopathy (VER).
Pleione (peacock orchid) is a small genus of predominantly terrestrial but sometimes epiphytic or lithophytic, miniature orchids.
 This genus is named after Pleione, mother of the Pleiades (in Greek mythology), and comprises about 20 species.
 Other common names of this genus include glory of the east, Himalayan crocus, Indian crocus and windowsill orchid.
 The genus "Diploconchium" is generally included here.
 "Pleione" is abbreviated to Pln in trade journals.
The species problem is the set of questions that arises when biologists attempt to define what a species is.
 Such a definition is called a species concept; there are at least 26 recognized species concepts.
 A species concept that works well for sexually reproducing organisms such as birds is useless for species that reproduce asexually, such as bacteria.
 The scientific study of the species problem has been called microtaxonomy.
The Kroombit tinker frog or Pleione's torrent frog (Taudactylus pleione) is a species of frog in the Myobatrachidae family.
 It is endemic to Central Queensland in Australia.
 It lives among rocks and leaf litter near small flowing streams.
Placonotus is a genus of beetles in the family Laemophloeidae.
 There are 40 currently recognized species, known from all continents except Antarctica.
 "Placonotus" species are small (~2mm), elongate, flattened beetles, characterized by long filiform antennae, presence of a frontoclypeal suture, open anterior coxal cavities, and broadly rounded intercoxal process of abdominal ventrite III.
 Males have the 8th abdominal segment modified to form claspers used during mating.
 Adults and larvae are found under dead bark, where they feed on fungi.
 Currently recognized species are:
Oplismenus undulatifolius, commonly known as wavyleaf basketgrass, is a species of perennial grass from the Poaceae family that is native to South Asia, East Asia, Southeast Asia, Australia, and Southern Africa.
 It can be found in countries such as Pakistan (Punjab & Kashmir), China, Japan, Korea, India, Australia, South Africa, Madagascar and has since been introduced to the Mid-Atlantic United States.
 There are no recognized subspecies in Catalogue of Life.
Wasps of the cosmopolitan genus Polistes (the only genus in the tribe Polistini) are the most familiar of the polistine wasps, and are the most common type of paper wasp in North America.
 It is also the single largest genus within the family Vespidae, with over 300 recognized species and subspecies.
 Their innate preferences for nest-building sites leads them to commonly build nests on human habitation, where they can be very unwelcome; although generally not aggressive, they can be provoked into defending their nests.
 All species are predatory, and they may consume large numbers of caterpillars, in which respect they are generally considered beneficial.
 The European paper wasp, "Polistes dominula", was introduced into the US about 1981 and has quickly spread throughout most of the country, in most cases replacing native species within a few years.
 This species is very commonly mistaken for a yellow jacket, as it is black, strongly marked with yellow, and quite different from the native North American species of "Polistes".
 The cuckoo wasp, "Polistes sulcifer", is an obligate social parasite, whose only host is "P. dominula". "
Polistes annularis", whose species name is Latin for "ringed", is also known for its distinctive red body color. "
Polistes metricus" adults malaxate their insect prey by chewing them into a pulp, sucking out and ingesting the body fluids, then feeding the rest of the morsel to their larvae.
 The most widely distributed South American wasp species, "Polistes versicolor", is particularly common in the southeastern Brazilian states.
 This social wasp is commonly referred to as the yellow paper wasp due to the distinct yellow bands found on its thorax and abdomen.
 "Polistes" wasps can be identified by their characteristic flight; their long legs dangle below their bodies, which are also more slender than a yellow jacket.
