 transfer to the \V. Indies is told. — k>paringly cult, in 

 S. Fla. and in warnihouses of botanic gardens. Eaten 



cooked, as a vege-

 as a fruit ; widely 

 used in tropics.

ARUM (ancient name). Aracese. Wild Ginger. 

 Tuber-bearing low herbs, of few species, in Eu. and W. 

 Asia, most of them grown in pots. 



Lvs. simple, the petiole sheathed at the base: spathe 

 convolute, variously colored, mostly including the short 

 spadi.\; pistillate fls. at the base. Monogr. by Engler in 

 DeCandoUe's Monographia,' Phanerogamarum, Vol. IL 



Arums are grown usually as oddities, mostly under the 

 general name of callas. Some of the species are hardy; 

 others, as A. palxstinum, are tender, and require glass- 

 house treatment. The kinds are managed in essentially 

 the same way as the fancy-leaved caladiums. Plant 

 the tubers sufficiently deep that roots may form from 

 near the top. Give rich soil, and water freely when 

 growing or in bloom. The hardy species should be 

 well mulched in late fall. They thrive best in partially 

 shaded places and in rich soil. Propagation is by 

 natural offsets; also by seeds or berries, which some 

 species produce freely. Some of the species are acrid- 

 poisonous.
