Bougainvillea glabra
Bougainvillea glabra, the lesser bougainvillea or paperflower,[3] is the most common species of bougainvillea used for bonsai.[4] The epithet 'glabra' comes from Latin and means "bald".[5] DescriptionIt is an evergreen, climbing shrub with thick, thorny stems and drooping branches that are glabrous or sparsely hairy. The leaves have a 3–10-millimetre-long (1⁄8–3⁄8 in) stem. The leaf blade is ovate to ovate-lanceolate, pointed or briefly pointed, 5 to 13 centimeters long and 3 to 6 centimeters wide, sparsely fluffy hairy on the underside and bald on the top. The leaf-like bracts are purple, oblong or elliptical, pointed, 65–90 mm (2+1⁄2–3+1⁄2 in) long and about 50 mm (2 in) wide. They tower over the flowers. These grow individually in pairs or in groups of three on flower stems about 3.5 millimeters long.[citation needed] The crown tube is greenish, clearly angled, about 2 centimeters long, sparsely downy hairy, ribbed and points away from the flower stalk. The tip is lobed five times and forms a short, spread, white or yellowish hem. The six to eight stamens have 8 to 13 millimeter long stamens. The ovary is about 2 millimeters long, the stylus 1 millimeter and the scar 2.5 millimeters.[6] It usually grows 3–3.5 m (10–12 ft) tall, occasionally up to 9 m (30 ft). Tiny white flowers usually appear in clusters surrounded by colorful papery bracts, hence the name paperflower. The leaves are dark green, variable in shape, up to 100 mm (4 in) long.[7] The flowers are about 0.4 cm (0.16 in) in diameter (the pink petal-like structures are not petals, but bracts).[8] CultivationB. glabra is heat and drought tolerant and frost sensitive. It is easily propagated by cuttings.[7] It needs full sunlight, warm weather and well drained soil to flower well. The species is often used in culture, in areas with frost in glass houses, otherwise outdoors. The similar Bougainvillea spectabilis, which differs from Bougainvillea glabra by the velvety-felty underside of the leaves, is also cultivated, but less frequently.[citation needed] UsesBeing of medical importance, the infusion of the plant's tender leaves and bracts is used orally to treat gastrointestinal problems (diarrhoea, stomach pain), and respiratory conditions (asthma, bronchitis, catarrh, chest pain, fever, pneumonia, whooping cough).[9] Gallery
