Notes

Tree 2-4 m tall. Flower buds white, when open yellow with reddish white stamens. Ripe fruit green.
Close to R. longiracemosa (to which S 18905 and SF 35738 were reckoned in the Identification List; actually they belong here, like S 20935), and to R. macrantha; the differences have been pointed out in the Latin diagnosis.
