Question: Do Macropidia and Crescentia only produce flowers?
Context: Crescentia (calabash tree, huingo, krabasi, or kalebas) is a genus of six species of flowering plants in the family Bignoniaceae, native to southern North America, the Caribbean, Central America and northern South America.  The species are moderate-size trees growing to 10 m tall, and producing large spherical fruits, with a thin, hard shell and soft pulp, up to 25 cm in diameter. Persoonia micranthera, commonly known as the small-flowered snottygobble, is an endangered prostrate shrub with yellow flowers and thin bark.  It grows only on two peaks, Bluff Knoll and Isongerup Peak, in the eastern section of the Stirling Range, Western Australia.  A slow-growing plant, it takes more than six years to produce flowers and seed. Eulophia streptopetala is a species of orchid.  It can be found from Eritrea to South Africa and also in Yemen.  This species is widespread and is usually found at forest margins, in bushy scrub, or in grasslands from the coast to 2550 meters above sea level.  The plant produces a tall inflorescence originating from the subterranean pseudobulb that continues to produce flowers over several months.  The flowers are approximately one centimetre in diameter with yellow petals and brownish green striped sepals. Bryophytes are an informal group consisting of three divisions of non-vascular land plants (embryophytes), the liverworts, hornworts and mosses.  They are characteristically limited in size and prefer moist habitats although they can survive in drier environments.  The bryophytes consist of about 20,000 plant species.  Bryophytes produce enclosed reproductive structures (gametangia and sporangia), but they do not produce flowers or seeds.  They reproduce via spores. Bryophytes are usually considered to be a paraphyletic group and not a monophyletic group, although some studies have produced contrary results.  Regardless of their status, the name is convenient and remains in use as an informal collective term.  The term "bryophyte" comes from Greek βρύον, "bryon" "tree-moss, oyster-green" + φυτόν – "phyton" "plant". Stylidium marradongense is a species that belongs to the genus "Stylidium" (family Stylidiaceae).  The specific epithet "leeuwinense" refers to the Marradong region in Western Australia where the species is located.  It is an herbaceous perennial that grows from 15–50 cm tall and has divided stems covered with tile-like leaves that are arranged in a spiral formation around the stem.  The lanceolate leaves are basifixed and held closely against the stems.  The leaves are around 1.5-2.0 mm long and 0.5-0.8 mm wide.  Terminal inflorescences are racemose or spike-like and produce flowers that are shades of pink or white with pink at the base of the lobes and bloom from September to November in their native range.  "S. marradongense" is only known from south-western Western Australia from Mount Saddleback to Marradong.  Its habitat is recorded as being sandy laterite soils in open Jarrah forest with other species such as "Banksia grandis", "Banksia sessilis", and "Persoonia longifolia".  "S. marradongense" is closely associated with "S. preissii" because they both lack throat appendages.  It differs from "S. preissii" by its spike-like racemes, apical mucro, and conical, capitate stigmas. Piperia candida is a species of orchid known by the common names whiteflower rein orchid, slender white piperia, and white-flowered piperia.  It is native to western North America from Alaska to the San Francisco Bay Area, where it grows in coniferous forests and other habitat in coastal and inland mountain ranges within 150 kilometers of the coast.  It grows erect to about half a meter in maximum height from a bulbous caudex.  The basal leaves are up to 18 centimeters long by 3 wide.  Leaves higher on the stem are much reduced.  The upper part of the stem is a spikelike inflorescence of up to 100 small flowers, mostly arranged along one side of the stem.  The fragrant, honey-scented flowers are whiter than those of other "Piperia", but sometimes green-tinged or -veined, or green with white margins.  The status of this species in the wild is difficult to determine because most populations are small and may produce flowers only rarely. Macropidia fuliginosa, the sole species of genus Macropidia, is a perennial rhizomatous flowering plant.  Commonly known as the black kangaroo paw, it is endemic to Southwest Australia, specifically from Perth to Geraldton in the north of the region. Rebutia is a genus in the family Cactaceae, native to Bolivia and Argentina.  They are generally small, colorful cacti, globular in form, which freely produce flowers that are relatively large in relation to the body.  They have no distinctive ribs, but do have regularly arranged small tubercles.  They are considered fairly easy to grow and they may produce large quantities of seeds that germinate freely around the parent plant. Stylidium longicornu is a dicotyledonous plant that belongs to the genus "Stylidium" (family Stylidiaceae).  It is an annual plant that grows from 10 to 30 cm tall.  The obovate to spathulate leaves form a basal rosettes around the stem.  The leaves are around 4–6 mm long.  Inflorescences are unbranched racemes and produce flowers that are violet with white at the base and bloom from June to August in their native range.  "S. longicornu" is endemic to the Kimberley region in Western Australia.  Its habitat is recorded as being sand flats near sandstone.  It grows in the presence of "S. lobuliflorum", "Rhynchospora", and "Leptocarpus". The 'dwarf' elm cultivar Ulmus 'Jacqueline Hillier' ('JH') is an elm of uncertain origin.  It was cloned from a specimen found in a private garden in Selly Park, Birmingham, England, in 1966.  The garden's owner told Hillier that it might have been introduced from outside the country by a relative.  Hillier at first conjectured "U. minor", as did Heybroek (2009).  Identical-looking elm cultivars in Russia (if they are not imported 'JH') are labelled forms of Siberian Elm, "Ulmus pumila", which is known to produce 'JH'-type long shoots.  Melville considered 'JH' a hybrid cultivar from the 'Elegantissima' group of "Ulmus × hollandica".  Uncertainty about its parentage has led most nurserymen to list the tree simply as "Ulmus" 'Jacqueline Hillier'.  'JH' is not known to produce flowers and samarae, or (when grown from cuttings) root suckers.
