B. oycoviensis Bess. leaves were found to contain compounds characteristic of B. "nova" i.e. myricitrin, isoquercitrin and probably also kaempferol 3-rhamno-7-glucoside, quercetin 3,7,4'-trimethyl ether, and quercetin 7,3',4'-trimethyl ether. They also contain compounds which occur in B. pendula Roth. (kaempferol 3-glucoside, isorhamnetin 3-glactoside, 6-methoxykaempferide, acacetin 7-glucoside, and probably scutellarein 7-glycoside). These biochemical traits bring out still better the hybrid origin of B. oycoviensis
