Question: Are both Nerium or Thuja could be a shrub?
Context: Gordonia lasianthus (loblolly-bay, holly-bay, gordonia, or bay) is a small to medium-sized evergreen tree or shrub found in acid, swampy soils of pinelands and bays on the Atlantic and Gulf Coastal Plains of the southeastern United States.  It is a member of the Tea or Theaceae family.  It is slow growing with soft, light-colored(Varies in color from Cream to Carmine), fine-grained wood of little commercial value, although loblolly-bay could be managed as a source of pulpwood.  When older specimens are cut, the wood exudes a strong scent.  It is similar to a mixture of fresh oranges and pine sap.  The bark of the adult tree varies from medium grey to a red brown coloration.  Dead adult specimens of loblolly bay exhibit a lustorous shine when exposed to sunlight for several years.  The white showy flowers and shiny foliage make it a desirable ornamental, but it is not easy to cultivate.  Deer browse stump sprouts heavily. Salacia oblonga is a strangling shrub native to India and Sri Lanka.  In traditional medicines it is used for the treatment of diabetes.  A study showed its extract may be beneficial for type 2 diabetes after a high-carbohydrate meal.  Another study suggested that 1000 mg of salacia oblonga extract following a meal after 12 hours of fasting could reduce blood glucose levels, while a dosage of 750 mg extract showed no impact. Argocoffeopsis lemblinii is an extinct relative of the coffee within the Rubiaceae family.  It is only known by the holotype collected by French botanist Auguste Jean Baptiste Chevalier in January 1907 in the valley of the Agnéby river in Côte d'Ivoire and was not found during subsequent surveys.  "Argocoffeopsis lemblinii" was a much branched shrub which could reach a height of about 50 centimetres.  The flowers were white, the small fruits spheroid.  Its habitat were forests. Thuja ( ) is a genus of coniferous trees in the Cupressaceae (cypress family).  There are five species in the genus, two native to North America and three native to eastern Asia.  The genus is monophyletic and sister to "Thujopsis".  Members are commonly known as arborvitaes, (from Latin for "tree of life") thujas or cedars. Gouania hillebrandii (also known as hairyfruit chewstick) is an endangered species of "Gouania" that is endemic to Hawaii.  It formerly could be found on Maui, Molokaʻ i, Lānaʻ i and Kahoʻ olawe, but is today restricted to western Maui near Lahaina.  It inhabits dry forests at elevations of 244 - .  Hairyfruit chewstick is a single branched shrub with small, white flowers. Meadows are of ecological importance because they are open, sunny areas that attract and support flora and fauna that could not thrive in other conditions.  Meadows may be naturally occurring or artificially created from cleared shrub or woodland.  They often host a multitude of wildlife, providing areas for courtship displays, nesting, food gathering and sometimes sheltering if the vegetation is high enough.  Many meadows support a wide array of wildflowers, which makes them of utmost importance to pollinating insects, including bees, and hence the entire ecosystem. Nerium oleander is a shrub or small tree in the dogbane family Apocynaceae, toxic in all its parts.  It is the only species currently classified in the genus Nerium.  It is most commonly known as nerium or oleander, from its superficial resemblance to the unrelated olive "Olea".  It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested.  The ancient city of Volubilis in Morocco may have taken its name from the Berber name "oualilt" for the flower.  Oleander is one of the most poisonous commonly grown garden plants.
