Begonia acetosa is a species of flowering plant in the family Begoniaceae, native to southeastern Brazil. [2] It is used to create new begonia hybrids due to its attractive foliage. [3] [4] Begonia acetosa has been cultivated in the United States since 1946, when Mulford B. Foster introduced the species from forested mountains near Rio de Janeiro. [5] It was first described in 1831 by José Mariano de Conceição Vellozo. The specific epithet acetosa means 'acid' or 'sour', referring to the rhubarb-like taste of its leaves. [5]

Begonia acetosa is an herbaceous, creeping, rhizomatous begonia, growing up to 1 m (3 ft) tall. It has thick, horizontally spreading, pale green branches. Leaves are ovate to orbicular, and asymmetrical. [6] [5] The leaves are a dull green on the upper surface and a deep wine red on the under surface. Both the underside and upper surface of the leaf are covered with a dense layer of short white hairs. Petioles are a rusty reddish brown to a deep red, and covered in short, woolly hairs. The flowers of B. acetosa are white. [6]

<i>Begonia masoniana</i> Species of flowering plant

Begonia masoniana, the iron cross begonia, is a species of plant in the family Begoniaceae, native to southern China and northern Vietnam. It was originally described from cultivated plants of unknown origin and was only much later rediscovered in the wild. It is a rhizomatous perennial begonia growing to 0.5 metres (20 in), bearing large, asymmetrical, textured green leaves covered in reddish hairs, with a prominent dark brown pattern in the centre of each leaf, reminiscent of the German Iron Cross. It produces small white flowers in erect panicles, but is cultivated mainly for its foliage effect. In temperate regions it must be grown under glass, or in a completely frost-free environment. Not to be confused with the similar looking species Begonia variegata, from Vietnam. Although sometimes (incorrectly) considered a Rex begonia, this species is classified in the related section Coelocentrum.
