Begonia malachosticta

Red, bristly stems announce Begonia malachosticta before the leaves do — setose petioles and canes that are hard to mistake for anything else in the genus. Described by Kollmann and Fontana from the shaded, humid tropical forests of Ecuador, it produces asymmetrical, elongate-ovate leaves with a dark green upper surface densely spotted in pale green to whitish maculations, deep red beneath. The plant grows as an upright, naturally branching cane rooted in the rich organic substrate of its native forest floor, reaching a moderate size that stays manageable indoors while remaining genuinely uncommon in the UK trade.
