Family 92. MALVACEAE.* 



Mallow Family. 



Herbs or shrubs with mucilaginous juice, stellate pubescence, and alternate, 

 palmately veined, commonly lobed or divided leaves. Stipules small, deciduous. 

 Flowers regular, perfect or polygamo-dioecious. Calyx 5-lobed, valvate in bud, often 

 involucellate-bracteate at the base. Petals 5, hypogynous, convolute in the bud, 

 fused at the base with the stamineal tube. Stamens numerous, hypogynous, forming 

 a monodelphous tube about the pistil. Pistil of several to many carpels, commonly 

 with as many cells as styles or stigmas ; ovules 1 to several in each carpel. Ovary 

 superior. Fruit a loculicidal capsule or the carpels falling separately. Seeds reni- 

 form. Embryo curved ; cotyledons plicate or conduplicate ; endosperm scanty. 



A family of about 45 genera distributed throughout the temperate and tropical parts of the world.

 ticulate. 9. Malva.
