The leaves of the taxon B. "nova" were found to contain myricitrin, hyperoside, quercetin 3-glucoside, myricetin 3-digalactoside, quercitrin, quercetin 3-arabinoside, hesperidin, and probably also kaempferol 3-rhamno-7--glucoside, quercetin 3,7,4'-trimethyl ether, quercetin 7,3',4'-trimethyl ether, and dihydrohyperoside. Jentys-Szaferawa has advanced a supposition that B. "nova" may descend from B. humilis Schrk., however, since the composition of the leaf flavonoids present in the two taxa compared is quite different, these biochemical traits preclude such a possibility
