foliage of African and East Indian species of Cassia (Senna). 

 The fibres of Orotalaria 

 are strong, durable, 

 and used for making 

 cordage and coarse 

 cloth. The Tamarind 

 ( Tamarindus Indica) 

 grows in North Africa 

 and East India. Very 

 many representatives 

 of the family are culti- 

 vated for ornament, as 

 species of Lupinus, La- 

 burnum, Petalostemon, 

 Rohinia, Wistaria, Phaseolus, Lathyrus, Acacia, Mimosa, 

 etc. The Sensitive-plant is Mimosa pudica, from South 

 America (Fig. 329). 



13. Anacardiaceae. The Cashew family. Trees 

 and shrubs, with milky resinous juice, often poisonous. 

 Flowers small, regular, pentandrous. Species chiefly tropi- 

 cal, numbering about four hundred and fifty. The fruit 

 called Mango is produced by a species from India, Mangi- 

 fera Indica, now cultivated in most warm countries. The 

 Cashew-nut is the fruit of Anacardium oeddentak, a tree 

 of the West Indies ; and the Pistachio-nut of Pistada 

 vera, a tree of Asia. The resinous substance Mastic is 

 obtained from Pistol Lentiscus from the Mediterranean 

 region. Our common representatives of this family belong 

 to the genus Rhus. The Sumac {R. typhina and R. glabra) 

 contains much tannin in the leaves, which are, therefore, 

 used in tanning. The Poison Ivy (R. Toxicodendron), the 



Fig. 329. The Sensitive-plant.
