Calyx and corolla 5(-6-7)-partite, the latter more or less rotate, infundibuliform or campanulate. Stamens 5, attached at the base of the corolla or about the middle, often monadelphous to form a tube-like membrane, glandular or not and adnate to the corolla throat; anthers basifixed or versatile, dehiscing longitudinally or by pores. Ovary subglobose, style slender, stigma capitate. Capsule subglobose, dehiscing by 5 valves or irregularly. Seeds many, small.

    c. 200 worldwide species, but cheifly in E. Asia and N. America, being absent from the Artic area and New Zealand. Represented in Pakistan by 7 species, of which Lysimachia vulgaris is adventive in Kashmir.
