 have irregular flowers ; a six-parted perianth ; six stamens

 the Plantain (Jf. paradisiaca) are large herbs, ten to 

 fifteen feet high. Their fruit constitutes almost the entire

 arutidinaeea, & native of Tropical America, the starch 

 called Arrow-root is obtained. Common cultivated plants 

 of this family are the many species of Canna (Fig. 294) 

 and Strelitzia Regina, the latter from South Africa.
