(Plates 62, 65.) 



Herbs, shrubs or trees. Leaves often, with stipules. 

 Flowers racemose or solitary, bisexual, mostly zygomorphic. 

 Sepals 4, sometimes connate. Petals 4 (rarely o), clawed, 

 often unequal. Stamens 4, 6, 8 or many, often inserted 

 on an androphore. Carpels connate, the ovary sup- 

 ported by a gynophore, oo -ovuled. Fruit a capsule or 

 berry; seeds kidney-shaped. Embryo incurved. (Fig. 704.) 



Over 300 species in the warmer countries. 



The family includes few plants of economic import- 

 ance, e.g. Capparis spinosa, a shrub of the Mediterranean 

 countries ; its flower-buds are the capers of commerce. 

 Several South African representatives of the genus, e.g. 

 C. oleoides, are locally employed for the same purpose.
