Genera 56, species 610, the herbs chiefly natives of temperate regions and the shrubs and trees of the 
tropics, where they are in some instances very large. ‘The teak-wood (Tectona grandis), native of India, 
justly styled the “ Oak of the East,” is a timber tree of immense size and great dian tite often attaining 
the height of 100 feet. The wood contains silex. The medicinal properties of the tribe are little known ot 
unimportant.
