Question: Do both Bidens and Pimelea have poisonous species in them?
Context: Bidens is a genus of flowering plants in the aster family, Asteraceae.  The common names beggarticks, black jack, burr marigolds, cobbler's pegs, Spanish needles, stickseeds, tickseeds and tickseed sunflowers refer to the fruits of the plants, most of which are bristly and barbed, with two sharp pappi at the end.  The generic name refers to the same character; "Bidens" comes from the Latin "bis" ("two") and "dens" ("tooth"). Lactarius vinaceorufescens, commonly known as the yellow-staining milkcap or the yellow-latex milky, is a poisonous species of fungus in the family Russulaceae.  It produces mushrooms with pinkish-cinnamon caps up to 12 cm wide held by pinkish-white stems up to 7 cm long.  The closely spaced whitish to pinkish buff gills develop wine-red spots in age.  When it is cut or injured, the mushroom oozes a white latex that rapidly turns bright sulfur-yellow.  The species, common and widely distributed in North America, grows in the ground in association with conifer trees.  There are several other "Lactarius" species that bear resemblance to "L. vinaceorufescens", but most can be distinguished by differences in staining reactions, macroscopic characteristics, or habitat. Amanita bisporigera is a deadly poisonous species of fungus in the family Amanitaceae.  It is commonly known as the eastern North American destroying angel or just as the destroying angel, although the fungus shares this latter name with three other lethal white "Amanita" species, "A. ocreata", "A. verna" and "A. virosa".  The fruit bodies are found on the ground in mixed coniferous and deciduous forests of eastern North America south to Mexico, but are rare in western North America; the fungus has also been found in pine plantations in Colombia.  The mushroom has a smooth white cap that can reach up to 10 cm across, and a stipe, up to 14 cm long by 1.8 cm thick, that has a delicate white skirt-like ring near the top.  The bulbous stipe base is covered with a membranous sac-like volva.  The white gills are free from attachment to the stalk and crowded closely together.  As the species name suggests, "A. bisporigera" typically bears two spores on the basidia, although this characteristic is not as immutable as was once thought. Inocybe lacera (commonly known as the torn tibrecap) is a poisonous species of mushroom in the genus "Inocybe".  Its appearance is that of a typical "little brown mushroom": small, brown and indistinct.  However, it is distinguishable by its microscopic features, particularly its long, smooth spores.  As with many other species of "Inocybe", "I. lacera" contains the poisonous chemical muscarine which, if consumed, can lead to salivation, lacrimation, urination, defecation, gastrointestinal problems and emesis.  Found in Europe and North America, it typically grows in autumn in mixed woods, favouring sandy soil.  There are several documented subspecies in addition to the main "I. lacera" var "lacera", including the dwarf form "I. lacera" var.  "subsquarrosa" and "I. lacera" var.  "heterosperma", found in North America. Baorangia bicolor, also known as the two-colored bolete or red and yellow bolete after its two-tone coloring scheme of red and yellow, is an edible fungus in the genus "Baorangia".  It inhabits most of eastern North America, primarily east of the Rocky Mountains and in season during the summer and fall months but can be found across the globe in China and Nepal.  Its fruit body, the mushroom, is classed as medium or large in size, which helps distinguish it from the many similar appearing species that have a smaller stature.  A deep blue/indigo bruising of the pore surface and a less dramatic bruising coloration change in the stem over a period of several minutes are identifying characteristics that distinguish it from the similar poisonous species "Boletus sensibilis".  There are two variations of this species, variety "borealis" and variety "subreticulatus", and several other similar species of fungi are not poisonous. The red-backed poison frog ("Ranitomeya reticulata") is a species of frog in the family Dendrobatidae.  It is an arboreal insectivorous species, and is the second-most poisonous species in the genus, after "R. variabilis".  Like many species of small, poisonous frogs native to South America, it is grouped with the poison dart frogs, and is a moderately toxic species, containing poison capable of causing serious injury to humans, and death in animals such as chickens. "R. reticulata" is native to the Amazon rainforest in Peru and Ecuador. Pimelea actea is a small coastal plant native to New Zealand.  It was named and described by Colin J. Burrows in 2008 as part of a revision of the New Zealand "Pimelea", a project he had begun as a Master's thesis in the 1950s and continued in his retirement.  Burrows described the species, which for some time had been referred to as "Pimelea" "Turakina", from a specimen collected in 1968, now in the Auckland Museum.  Its species name, "actea", means "coastal". The bog beggarticks (Bidens conjuncta) is a species of flowering plant in the sunflower family.  It belongs to the genus "Bidens", collectively called "kokoʻolau" or "koʻokoʻolau" in the Hawaiian language.  "Bidens conjuncta" is found only on western Maui. The Oʻ ahu beggarticks or poplar-leaved "Bidens (Bidens populifolia") is a species of flowering plant in the family Asteraceae.  It belongs to the genus "Bidens", collectively called "kokoʻ olau" or "koʻ okoʻ olau" in the Hawaiian language.  It is found only in the Koʻ olau Range on Oʻ ahu. Pimelea (often seen spelled "Pimelia", which is the name of a genus of beetles) is a genus of plants belonging to the family Thymelaeaceae.  There are about 80 species in the genus, which is native to Australia and New Zealand.  Many of the species are poisonous to cattle and horses.
