412 Select Plants for Industrial Culture 



From Dr. Hance we know, that the solid base of the stem 

 forms a very choice vegetable, largely used in China, where this tall 

 water-grass undergoes regular cultivation like the Trapa. 



Zizania miliacea, Michaux.* 



Southern part of North- America, West-Indies. Tall and perennial, 

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

 to Pursh; while according to Chapman's note it is generally distri- 

 buted like Z. aquatica, with which it has similar use. In Southern 

 Brazil occurs a similar if not identical grass namely Z. microstachya 

 (Neesj. 



Zizyphus Joazeiro, Martius. 



Brazil. Recommended as yielding edible fruit in arid regions. 



Zizyphus Jujuba, Lamarck. 



From India to China and 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 within the temperate 

 zone in warm regions. 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 (Cavanilles) and some other trees. 

 Often the cocoons are merely collected in the forests. 



Zizyphus Lotus, Lamarck. 



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, and are quite a staple- 

 product for the local fruit-markets there (Dr. Shaw). Z. nummularia 

 (Wight and Arnott) is an allied species from the mountains of India, 

 ascending to about 3,000 feet. It is much used for garden-hedges. 

 The fruit is sweet and acidulous and of a pleasant flavor (Brandis). 



Zizyphus MiStal, Grisebach. 



Argentina. A fine tree with edible fruits. 



Zizyphus rugosa, Lamarck. 



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

 than Z. Lotus. The drupe of this is also edible, and. the same may be 

 said of a few other Indian species. 



Zizpyhus Sinensis, Lamarck. 



China and Japan. Similar in use to the last. 



Zizyphus Spina Christi, Willdenow. 



Middle and North-Africa, South- Western Asia. Rather a hedge- 

 plant than a fruit-bush.
