MALVACEAE. Mallow Family 



Herbs or soft-woody shrubs with mucilaginous juice, tough fibrous inner bark, 

 and usually stellate pubescence. Leaves alternate, simple, stipulate, the blades 

 palmately veined and commonly palmately lobed. Flowers commonly perfect, 

 sometimes polygamous or dioecious, regular. Calyx with 5 lobes, valvate in the 

 bud, often with an involucel of bractlets at base. Petals 5, twisted in the bud. 

 Stamens indefinite, hypogj^nous, monadelphous in a column or tube around the 

 pistils, the petals inserted on the base of the tube. Pistil 1, composed of several 

 to many carpels, the superior ovary commonly with as many cells as styles or 

 stigmas. Fruit a loculicidal capsule, or composed of a circle of united carpels 

 separating at maturity. — Genera 32, species 850, all continents.
