Question: Valeriana and Maranta are both a genus of what types of plants?
Context: Maranta is a genus of flowering plants in the family Marantaceae, native to tropical Central and South America and the West Indies.  "Maranta" was named for Bartolomeo Maranta, an Italian physician and botanist of the sixteenth century. Tessmannianthus is a genus of flowering plants in the family Melastomataceae.  There are seven species distributed in Central and South America.  They are medium to large trees up to 40 meters tall.  The flowers are heterantherous, bearing two types of stamens.  These plants are rare, and some are narrow endemics known from only one location. Medinilla myriantha is a species of semi-epiphytic plant with pink flowers that are produced in the summer and spring.  These plants are known to grow up to six feet tall.  It is also known as the Malaysian orchid, but is actually a plant in the family Melastomataceae and is native to the Philippines. There are many other types of Medinilla Myriantha such as the rose grapes,pixi,pink lantern and so on.Some of these later have fruit usually purple pink etc.These plants also are useful to grow if the place you live in humid.The genus has about a hundred varieties but only a few are commercially sold. Urticating hairs or urticating bristles, i.e. irritating hairs, are one of the primary defense mechanisms used by numerous plants, almost all New World tarantulas, and various lepidopteran caterpillars.  "Urtica" is Latin for "nettle" (stinging nettles are in the genus "Urtica"), and hairs that urticate are characteristic of this type of plant, and many other plants in several families.  This term also refers to certain types of barbed hairs that cover the dorsal and posterior surface of a tarantula's or caterpillar's abdomen.  Many tarantula species eject hairs from their abdomens, directing them toward potential attackers.  These hairs can embed themselves in the other animal's skin or eyes, causing physical irritation, usually to great discomfort. Valeriana sitchensis is a species of valerian known by the common name Sitka valerian.  It is native to northwestern North America from Alaska and northern Canada to Montana to northern California, where it grows in many types of habitat, including moist mountain forests.  In moist subalpine meadows, it is often one of the most common plants.  This is a rhizomatous perennial herb producing a stout, erect stem to about 70 centimeters in maximum height, but known to exceed one meter at times.  The leaves vary in size and shape, often having deep lobes or being composed of several leaflets.  The inflorescence is a cyme of many white or pink-tinged flowers, each under a centimeter wide.  The flower has five corolla lobes and three whiskery stamens protruding from the center. Ginkgoites is a genus that refers to extinct plants belonging to Ginkgoaceae.  Fossils of these plants have been found around the globe during the Triassic, Jurassic and Cretaceous.  The name was created as a form genus in 1919 by Albert Seward who stated: "I ... propose to employ the name "Ginkgoites" for leaves that it is believed belong either to plants generically identical with "Ginkgo" or to very closely allied types". Exochorda is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan).  They are used as ornamental plants with the common name pearl bush, or pearlbush.  Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic study revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss.  As a single species the correct name is "E. racemosa". Valeriana is a genus of flowering plants in the family Caprifoliaceae, members of which may by commonly known as valerians.  It contains many species, including the garden valerian, "Valeriana officinalis".  Some species are native to Europe, others to North America and South America (especially in the Andes). Tobacco is the agricultural product of the leaves of plants in the genus "Nicotiana".  All species of "Nicotiana" contain the addictive drug nicotine—a stimulant and sedative contained in all parts of the plants except the seeds—which occurs in varying amounts depending on the species and variety cultivated.  See types of tobacco and curing of tobacco for more information. Schistocerca nitens is a species of grasshopper known by several common names, including vagrant grasshopper and gray bird grasshopper.  It is a close relative of the desert locust, which is in the same genus.  This grasshopper is native to southern North America including Mexico and the southwestern United States from California to Texas.  Can also be found in parts of mid atlantic states.  Recently found on Long Island New York.  It is also present in parts of Central America.  It lives in many habitats including desert, woodland, and lower elevation mountainous areas.  It is a large grasshopper, reaching lengths of 4 to 7 centimeters.  It is mostly brown and gray spotted or patched in cryptic coloration.  This species is known as a pest on ornamental plants and many types of crop plants.
