Question: Are Buckinghamia and Stipa plants?

full_context: Document 1: Backhousia: Backhousia is a genus of thirteen currently known species of flowering plants in the family Myrtaceae. All the currently known species grow naturally only (endemic) in Australia in the rainforests and seasonally dry forests of Queensland, New South Wales and Western Australia.
Document 2: Cardwellia: Cardwellia is a genus of a sole described species of large trees, constituting a part of the plant family Proteaceae. The species Cardwellia sublimis (northern silky oak) grows naturally only (endemic) in the rainforests of the wet tropics region of north eastern Queensland, Australia. Other common names include bull oak, golden spanglewood, lacewood, oak and oongaary. The compound leaves have up to 17 leaflets. It produces white inflorescences followed by woody fruits which are prominently displayed outside the canopy.
Document 3: Macadamia: Macadamia is a genus of four species of trees indigenous to Australia and constituting part of the plant family Proteaceae. They are native to north eastern New South Wales and central and south eastern Queensland. The tree is commercially important for its fruit, the macadamia nuts (or simply "macadamia"). Other names include Queensland nut, bush nut, maroochi nut, bauple nut, and Hawaii nut. In Australian Aboriginal languages, the fruit is known by names such as "bauple", "gyndl", "jindilli", and "boombera". Previously, more species with disjunct distributions were named as members of this genus "Macadamia". Genetics and morphological studies more recently published in 2008 show they have separated from the genus "Macadamia", correlating less closely than thought from earlier morphological studies. The species previously named in the "Macadamia" genus may still be referred to overall by the descriptive, non-scientific name of macadamia; their disjunct distributions and current scientific names are:
Document 4: Buckinghamia: Buckinghamia is a genus of only two known species of trees, belonging to the plant family Proteaceae. They grow naturally only (endemic) in the rainforests of the wet tropics region of north eastern Queensland, Australia. The ivory curl flower, "B. celsissima", is the well known, popular and widely cultivated species in gardens and parks, in eastern and southern mainland Australia, and additionally as street trees north from about Brisbane. The second species, "B. ferruginiflora", was only recently described in 1988.
Document 5: Bauhinia divaricata: Bauhinia divaricata is a species of flowering shrub of the family Fabaceae. "B. divaricata" is the type species of the genus "Bauhinia". One common name for this species is pom pom orchid tree. It is native to China, Jamaica, India and also grows in the southern half of Florida. It has white bi-lobed leaves that alternate.
Document 6: Bismarckia: Bismarckia is a monotypic genus of flowering plant in the palm family endemic to western and northern Madagascar where they grow in open grassland. The genus is named for the first chancellor of the German Empire Otto von Bismarck and the epithet for its only species, Bismarckia nobilis, comes from Latin for 'noble'.
Document 7: Cunonia: Cunonia is a genus of shrubs and trees in the family Cunoniaceae. The genus has a disjunct distribution, with 24 species endemic to New Caledonia in the Pacific, and one species (Cunonia capensis) in Southern Africa. Leaves are opposite, simple or pinnate with a margin entire to serrate. Interpetiolar stipules are often conspicuous and generally enclose buds to form a spoon-like shape (hence the common name "Butterspoon Tree" for "Cunonia capensis"). Flowers are bisexual, white, red (pink to purple), or green, arranged in racemes. The fruit is a capsule opening first around the base then vertically, seeds are winged.
Document 8: Festuca: Festuca (fescue) is a genus of flowering plants belonging to the grass family, Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of 10 - and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass ("Lolium"), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus "Festuca" into the genus "Lolium".
Document 9: Stipa: Stipa is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae.
Document 10: Amherstia: Amherstia nobilis (Burmese: သော်ကကြီး ] ; the Pride of Burma, in the Fabaceae family) is a tropical tree with large, showy flowers. It is the only member of the genus Amherstia. It is widely cultivated for ornament in the humid tropics, but is very rare in the wild and has only been collected from its native habitat a few times. It is native to Burma (Myanmar), hence the common name. The scientific name commemorates Lady Amherst, (as does Lady Amherst's pheasant) and also her daughter Sarah. Another common name, the Orchid Tree, is otherwise reserved for members of the genus "Bauhinia".
Document 11: Achnatherum: Achnatherum is a genus of plants which includes several species of needlegrass. Several needlegrass species have been switched between "Achnatherum" and genus "Stipa"; taxonomy between the two closely related genera is still uncertain.
Document 12: Schizachyrium scoparium: Schizachyrium scoparium, commonly known as little bluestem or beard grass, is a North American prairie grass native to most of the United States, except California, Nevada, and Oregon, and a small area north of the Canada–US border. Its greatest manifestation has always been in the Midwestern prairies. Little bluestem is a perennial bunchgrass and is prominent in tallgrass prairie, along with big bluestem ("Andropogon gerardi"), indiangrass ("Sorghastrum nutans") and switchgrass ("Panicum virgatum"). It is a warm-season species, meaning it employs the C photosynthetic pathway.
Document 13: Fimbristylis: Fimbristylis is a genus of sedges. A plant in this genus may be known commonly as a fimbry, fimbristyle, or fringe-rush. There are 200 to 300 species distributed worldwide. Several continents have native species but many species have been introduced to regions where they are not native. Some are considered weeds. These are typical sedges in appearance, with stiff, ridged stems and cone-shaped terminal panicles of spikelets. They are found in wet environments, and are most diverse in tropical and subtropical regions.
Document 14: Poa: Poa is a genus of about 500 species of grasses, native to the temperate regions of both hemispheres. Common names include meadow-grass (mainly in Europe and Asia), bluegrass (mainly in North America), tussock (some New Zealand species), and speargrass. "Poa" (πόα) is Greek for "fodder". "Poa" are members of the Pooideae subfamily of the Poaceae family.
Document 15: Stillingia spinulosa: Stillingia spinulosa is a species of flowering plant in the euphorb family known by the common name annual toothleaf. It is native to the southwestern United States where it occurs in the creosote scrub of the deserts. It is an annual or perennial herb producing a clump of thick, leafy stems approaching a meter in maximum height. The alternately arranged leaves have shiny pointed oval blades 2 to 4 centimeters long and up to 1.2 centimeters wide which are lined with sharp teeth. The inflorescence is a stout spike of flowers 1 to 2 centimeters long. The plant is monoecious, and each spike has several male flowers at the tip and 1 or 2 fruit-bearing female flowers below these. Neither type of flower has petals. The ovary of the female flower develops into a three-lobed greenish capsule about half a centimeter wide. There is a tiny rough-surfaced seed in each of the three chambers of the fruit.
