The names Triosteum hirsutum Wallich and T. hirsutum Roxburgh have sometimes been applied to this species. Some confusion has arisen from different print versions of Roxburgh, Fl. Ind. 2: 180. 1824. The original descriptions of T. himalayanum Wallich and T. hirsutum Roxburgh can be found in only one of these print versions. The other print version includes the description of T. hirsutum Wallich, which appears to be a printing error. Triosteum hirsutum Roxburgh is attributed to a specimen collected in Chittagong, Bangladesh, now the basionym of Lasianthus hirsutus in the Rubiaceae (see p. 192).
