- Description
- Curtis's botanical magazine. London v. 79= ser. 3: v. 9 (1853) http://www.biodiversitylibrary.org/item/14357 Begonia rubroveinia SYN B. hatacoa - From the stove of Thomas Nuttall, Esq., Rainhill, near Preston, Lancashire, having been detected and brought home from Bhutan by his nephew, Mr. Booth, along, with the equally remarkable Begonia xanthina, figured at Tab. 4683 of the present work. It evidently belongs to the same group or tribe of the extensive genus of Begonia as that plant but is widely different in specific character. Description. Root a short thick caudex or rhizome, sending down numerous fibrous roots beneath. Stem short, scarcely branched, and bearing few leaves; terete, fleshy, red. Leaves two or three springing from the root, the rest alternate, rather large, on long, grooved, red petioles, from two to four or five inches long : the blade of the leaf measures about six inches in length, is obliquely (or inequilaterally) ovate, subcordate at the base, much and gradually acuminated into a long point; the margins inequally dentato-serrated, glabrous (as is the whole plant), the upper side dark satiny-green, glossy, marked and dashed with white blotches; the underside of a full but rather dull purple color, and the veins are prominent. Stipules, a pair of opposite ones at the base of the petioles, large, membranous, from a broad base tapering into a stipulate point, yellowish-green with a red central line. Peduncles axillary, solitary, red, terete, longer than the petiole and much slenderer, erect, bearing a corymb of eight to ten or more drooping flowers. Male and female flowers each with four spreading white sepals, the male the largest; in both, the two outer and larger, cordato-rotundate, slightly concave ones are the largest, and beautifully and longitudinally veined with red; the inner and smaller sepals are nearly elliptical and pure white. Anthers yellow, in a compact capitulum. Fruit three-winged, beautifully striated transversely with red ; two of the wings short and rounded ; the third very much elongated transversely and obtuse.
