CARDAMOAIUM.— CARDAMOM.— The fruit of Elettaria 

 Cardamomum (Syn. E. repens) (Fam. Zingiberacese), a peren- 

 nial herb (p. 242) indigenous to Farther India, and cultivated 

 near the Malabar Coast and in Ceylon. The commercial article 

 is obtained from wild plants growing in the southern part of 

 the western coast of Farther India. The fruit is gathered in 

 autumn — either the entire spike, when some of the fruits have 

 matured, or the full-grown fruits are cut from the rachis in suc- 

 cession as they ripen ; they are bleached by exposure to the sun.

 have been discharged from the capsules are inferior to those 

 which have been retained. A greater portion goes to Bombay, 

 from where it is estimated that 100,000 kilograms are exported 

 yearly to London. The commercial varieties are known as Mala- 

 bar and Mysore Cardamom.
