362 SELECT PLANTS FOR INDUSTRIAL CULTURE 



Zizanii fluitans, Michaux. (Hydrochloa Carolinensis, Beauvois.) 



Southern States of North America. This grass, floating in shallow 

 streams, or creeping on muddy banks of rivers or swamps, is praised 

 by Mr. C. Mohr as valuable for fodder, lasting throughout the 

 year. 



Zizania miliacea, Michaux.* 



Southern part of North America, West India. Tall and perennial, 

 but more restricted to the tide-water meadows and ditches, accord- 

 ing to Pursh ; but according to Chapman's note, generally distrib- 

 uted like Z. aquatica, with which it has similar use. In South 

 Brazil occurs a similar grass namely, Z. microstachya (Nees). 



Zizyphus Joazeiro, Martius. 



Brazil. Recommended as yielding fruit in arid regions. 



Zizyphus Jujuba, La Marck. 



From India to China, East Australia, extending also to tropical 

 Africa, ascending the Himalayas to 4,500 feet. This shrub or tree 

 can only be expected to bear its pleasant fruits in the warmer part 

 of the temperate zone. The fruit is red or yellow, and of the size 

 of a cherry. The Tussa silkworm, which, according to Dr. Forbes 

 Watson, is the most important and widely distributed of the wild 

 silk-insects of India, feeds on Z. Jujuba, but also on Terminalias, 

 Shorea, Bombax heptaphyllum, and some other trees. Often the 

 cocoons are merely collected in the forests. 



Zizyphus Lotus, La Marck. 



Countries around the Mediterranean Sea. The fruits are small 

 and less sweet than those of Z. vulgaris ; nevertheless they are 

 largely used for food in the native country of this bush. Z. num- 

 mularia (Wight and Arnott) is an allied species from the mountains 

 of India, ascending to 3,000 feet. It is much used for garden 

 hedges. The fruit is sweet and acidulous and of a pleasant flavour 

 (Brandis). 



Zizyphus Mistal, Grisebach. 



Argentina. A fine tree with edible fruits. 



Zizyphus rugosa, La Marck. 



Nepal and other mountainous parts of India. A small tree, hardier 

 than the last. The drupe of this is also edible, and the same may 

 be said of a few other Indian species. 



Zizyphus Sinensis, La Marck. 



China and Japan. Similar in use to the last.
