千屈菜
The family is named after the type genus, "Lythrum", the loosestrifes (e.g. "Lythrum salicaria" purple loosestrife) and also includes henna ("Lawsonia inermis"). It now includes the pomegranate, formerly classed in a separate family Punicaceae. The family also includes the widely cultivated crape myrtle trees. Botanically, the leaves are usually in pairs (opposite), and the flower petals emerge from the rim of the calyx tube. The petals often appear crumpled.
