5. LYSIMACHIA L. by E. Aitken
Annual or perennial, erect or decumbent herbs. Leaves simple, entire, alternate or opposite, sometimes on the same plant, base attenuate, often extending along winged petiole. Flowers borne singly in leaf axils, or in racemes or terminal clusters, usually 5-merous, occasionally 4-6-merous. Calyx divided almost to base. Corolla rotate or funnel-shaped, lobes connate below middle. Stamens attached at base of corolla lobes, included or sometimes exserted; anthers dehiscing by slits, rarely pores. Capsule ovoid or subglobose, 5-valved or burst- ing irregularly, many-seeded.
