Fam. 144. LYTHRACEAE Miso-hagi Ka Loosestrife Family 



Herbs or woody plants; leaves opposite or verticillate, rarely alternate, stipules absent or very small; flowers usually actino- 

 morphic, bisexual, solitary or paniculate; calyx tubular, the lobes valvate, often with an appendage between the lobes; petals on 

 the throat of calyx-tube, usually wrinkled in bud, sometimes absent; stamens 4 or 8, sometimes fewer, inserted on the tube; 

 anthers 2-locular; ovary superior, perfectly or imperfectly 2- to 6-locular, rarely 1-locular; style simple, solitary; ovules many, the 

 placentation typically axile; capsules longitudinally to transversely or sometimes irregularly dehiscent; seeds many, without 

 endosperm, the embryo straight. About 22 genera, with about 500 species, chiefly in the Tropics. 



lA. Trees or shrubs; placentae continuous on the style; stamens many, with long filaments; capsules loculicidally dehiscent; seeds winged.
