In single studies, dimethyl sulfate induced somatic mutations in Drosophila melanogaster and in stamen hairs of Tradescantia clone BNL 4430. 

Perianth usually composed of similar or subsimilar segments in two or one series, usually very conspicuous and petaloid and if united then connate in the lower part into a single tube, but if perianth of separate calyx and corolla then the branches modified into cladodes or else herbs or woody climbers or shrubs with one-celled ovary and six stamens or perianth dry and fruit dehiscent or else stamens three, two, or one on a column. 

FILAMENT The anther-bearing stalks of stamens also a threadlike series of cells attached to one another or a very long cylindrical single cell.

The flowers of most species have six sepals, arranged in two cycles. Sepals are the outermost whorl of a flower, typically leaf-like in appearance. The stamens, or male organs, of laurel flowers occur in three or four cycles, with three stamens in each. The flowers usually have a single pistil, or female organ, which contains a single ovule that develops into a seed after fertilization. The fruit of most species is aromatic, and is classified as a drupe, in that is has a fleshy outer layer and a hard inner layer with a single seed. 

The Androecium or Stamen System.—The andracium is the single or double whorl of male organs situated within or above the corolla. It is composed of stamens or microsporophylls.

Carpels and stamens numerous. Bark aromatic and bitter. Fruit a collection of follicles dehiscing dorsally.
