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 Indioa) 

 grows in North Africa 

 and East India. Very 

 many representatives 

 of the family are culti- 

 vated for ornament, as 

 species of Lupinus, Lor 

 burnum, Petalostemon, 

 Robinia, Wistaria, Phaseolus, Lathyrus, Acacia, Mimosa, 

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

 Amei'ica (Fig. 329). 



13. Anacardiacese. The Cashew family. Trees 

 and shrubs, with milky resinous juice, often poisonous. 

 Flowers small, regular, peutandrous. Species chiefly tropi- 

 cal, numbering about four hundred and fifty. The fruit 

 called Mai]go is produced by a species from India, Mangi- 

 fera Indica, now cultivated in most warm countries. The 

 Cashew-nut is the fruit of Anaeardium ocddentale, a tree 

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

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

 obtained from Pistaeia Lentisous from the Mediterranean 

 region. Our common representatives of this family belong 

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

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

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



Fig. 329. The Sensitive-plant.
