 cosmop. ; the smaller groups often confined to definite floral regions. 

 Most are herbs with sympodial rhiz. or bulbs; a few trop. and warm 

 temp, forms, e.g. Yucca, Dracaena, &c., are shrubs or trees, often 

 with an unusual mode of growth in thickness. Many are xero.; some, 

 e.g. Aloe and Gasteria, are succulent ; others, e.g. Phormium, have
