ARTOCARPUS 



ARUM 



B.M. 2869-2871, where the romantic story of its 

 transfer to the W. Indies is told.-^Sparingly cult, in 

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



cooked, as a vege- 

 table rather than 

 as a fruit; widely 

 used in tropics. 



integrifdlia, 

 Linn. f. JACK- 

 FRUIT or TREE. 

 Called also JACA. 

 Fig. 393. Tree, 30 

 ft., with milky 

 juice: Ivs. 4-6 in. long, 

 very various; those of 

 fertile branches nearly 

 obovate, entire; those of 

 higher branches more ob- 

 ovate and oblong; those 

 of young shoots from the 

 root very narrow, or 2-3- 

 lobed: fr. attaining a 

 length of 18 in. or more, 

 and weight of 30-40 Ibs. 

 G.C. III. 20:717. B.M. 

 2833, 2834. Gt. 39, p. 

 273. Gn. 35, p. 455. 

 Less palatable than the 

 bread-fruit, and usually 

 eaten only by natives 

 and coolies. 



Cannonii, Bull. Lvs. 

 varying from cordate to 

 deeply 3-lobed, 1 ft. long, 

 red beneath, bronzy crim- 

 son and purple above, 

 very showy. Society Isls. F.S. 21:2231, 2232. Per- 

 haps better included under Ficus Cannonii, according 

 to Nicholson, but here retained in Artocarpus. 



N. TAYLOR, f 



ARUM (ancient name). Aracex. 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 

 spadix; pistillate fls. at the base. Monogr. by Engler in 

 DeCandolle's Monographic Phanerogamarum, Vol. II. 

 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.

AA. Mature Ivs. hastate or sagittate. 

 B. Tuber round-flattened or oblate, the Ivs. and pedun- 

 cles arising from a depressed center: Ivs. appear-

 included. Asia Minor. Runs into many forms, with 

 variously marked spathes. Pots.

 middle lobe broad-ovate and nearly blunt: spathe about
