SELECT PLANTS READILY ELIGIBLE 



Zizania aquatica, Linne.* {Hydropyrum esculentum, Link.) 

 The Canada-Rice. In sliallow streams and around ponds 

 and lakes from Canada to Florida. This tall grass might 

 be readily naturalised. Although its gi^ain can be utilised 

 for bread-corn, we would wish to possess the plant chiefly to 

 obtain additional food of a superior kind for water-birds. 



Zizania latifolia, Hance.* {Hydropyrum latifolium, Grise- 

 bach.) 



The Kau-sun of China. In lakes of Amur, Manchuria, 

 China and J apan. Nearly related to the preceding species. 

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

 forms a very choice vegetable, largely used in Chiiia, where 

 this tall water-gi'ass undergoes regular cultivation like the 

 Trapa. 



Zizania miliacea, Michaux. 



Southern part of North America, "West India. Likewise 

 tall and perennial, but more restricted to the tide-water 

 meadows and ditches, according to Pursli; but according to 

 Chapman's note generally distributed like Z. aquatica, Avith 

 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 March. 



From India to China, East Australia, extending also to 

 tropical Africa, ascending the Himalayas to 4500 feet. This 

 shrub or tree can only be expected to bear its pleasant fruits 

 in the warmest part of our colony. The fruit is red or 

 yellow, and of the size of a cherry. 



Zizyphus Lotus, La March. 



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. nummularia (Wight and Arnott) is an allied 

 species from the mountains of India, ascending to 3000 feet. 

 It is much used for garden-hedges. The fruit is sweet and 

 acidulous and of a pleasant flavour (Brandis). 



Zizyphus rugosa. La March. 



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 March. 



China and J apan. Similar in use to the last.
