The flowers are bisexual, usually borne in groups of 3 in leaf axils, with large bracts covering the flower, but falling off as the flower matures. Each flower has a bell-shaped hypanthium, usually 4 or 6 tepals, six male stamens, 6 to 12 staminodes, and 6 to 12 carpels. The fruit is oval to cylindrical or urn-shaped, and splits into 2 to 4 equal valves. [2] [3]

Taxonomy

The genus Doryphora was first formally described in 1837 by Stephan Endlicher in Genera Plantarum Secundum Ordines Naturales Disposita, and the first species he described (the type species) was Doryphora sassafras . [4] [5] The name of the genus means "spear-carrier", a reference to the prominent appendages on the anthers. [6]
