Order VIII. CAPPARIDACEiE. 



Herbs or shrubs, with alternate leaves and perfect hypogynous flowers; related to 

 Cruciferce, having the sepals or lobes of the calyx and petals (with claws) 4, the

 valves fall away ; but the embryo is incurved rather than folded, and the juice or 

 herbage, although sometimes pungent (as in Capers), is generally nauseous or bitter. 

 — Stamens sometimes numerous, when 6 nearly equal in length, or not distinctly
