Described by Kingdon Ward, its discoverer, as ‘a compact small scrubby bush’. Leaves to about 11⁄2 in. long, elliptic or elliptic-ovate, with mostly four to seven spine-teeth on each side, dull grey-green and conspicuously veined above, white and scarcely veined beneath. Flowers (as seen) pale yellow, about 3⁄4 in. wide, many in compound clusters. Fruits not seen, described as having a short style.
This species was discovered by Kingdon Ward on Mount Japvo in the Naga hills of Assam in 1927 and introduced by him in 1935 during a second visit (KW 12573). Original plants of this sending grow at Borde Hill in Sussex and are 3 to 4 ft high. Dr Ahrendt placed it next to B. coxii, which it resembles in some respects, though obviously different in habit. But in the new Edinburgh classification the two species are placed in different subsections of the section Wallichianae.
