Mature buds are cylindrical, Шаблон:Cvt long and Шаблон:Cvt wide with a tapered, elongated operculum that is up to seven times as long as the floral cup. Flowering occurs from September to November and the flowers are yellowish green. The fruit is a woody, hemispherical to shortened spherical capsule Шаблон:Cvt long and Шаблон:Cvt wide with the valved protruding strongly.[1][2][3]
