Description: As B. argyrostigma in: The Botanical register London: Printed for James Ridgway 1815-1828. v. 8 (1822): Plate 666 http://www.biodiversitylibrary.org/item/9044 Silver-spotted Begonia. Said by Professor Link to be native of the Brazils, and to have been sent from the Gorenki Garden, at Moscow, to the Botanic Garden of Berlin, by Dr. Fischer. It has only lately been introduced into the collections of this country. Drawn at the Nursery of Messrs. Colvill, in the King's Road, Chelsea, where it is grown in the hothouse. The somewhat unwieldy specific name has been suggested to Dr. Fischer by the silvery spots of the foliage; a mark which we understand is not confined to this species of the genus. It has been figured in the above quoted periodical work by Professor Link, from whom we borrow the following account: '' Stem upright, branched, straggling, 2-3 feet high, very smooth, with brown sheathing circles above the petioles. Leaves alternate; petiole an inch long, cylindrical; blade semicordate, from the petiole to the tip 5-6 inches long, 2 inches broad, pointed, with somewhat cartilaginous slightly crenulated repand margin, very smooth, fleshy, at the upper surface marked with white roundish spots of various sizes produced by the disappearance of the green pigment in the cellular tissue, and containing two or more small pits in the middle of a green disk; at the under surface wholly red. Peduncles axillary, sustaining a many-flowered panicle. Bracts 2 on each pedicle, opposite, lanceolate, white, (caducous.) Pedicle white at the upper part. Corolla of 4 petals, white, without scent, two opposite petals of the four the largest. Filaments many, very short. Anthers oblong. Germen winged?'' We had no opportunity of describing the flowers ourselves.
