EUCALYPTUS TREES. 468 
Wales and Queensland. A nutritious perennial pas- 
ture-grass. 
Amarantus Blitum, Linné.—South Europe, North 
Africa, South-west Asia. This annual herb is a fa- 
vorite plant among allied ones for spinach ; but not 
only species of this genus, but also many other Ama- 
rantaceze serve as culinary herbs. 
Aponogeton distachyon, Thunberg.—South Africa. 
This curious water-plant, introduced already, might 
be naturalized in our ditches, swamps, and lakes, for 
the sake of its edible tubers. The scented flowering 
portion affords spinach. 
Aralia cordata, Thunberg. — China. The young 
shoots provide an excellent culinary vegetable. 
Arbutus Menziesii, Pursh. — North-west America. 
An evergreen tree, attaining a height of 150 feet. It 
belongs to the coast-tract exclusively. Wood exceed- 
ingly hard. The tree requires a deep, loamy soil, 
(Bolander); it would here be valuable at least asa 
highly ornamental garden-plant. 
Aristolochia Indica, Linné. —Tropical Asia and Poly- 
nesia. A perennial climber; the leaves famed as an 
alexipharmic. Can only be grown in places free from 
frost. 
Aristolochia recurvilabra, Hance.—The green Put- 
chuck of China. A medicinal plant, largely obtained 
at Ningpo. The present value of its export is from 
£20,000 to £30,000 annually. 
Artemisia Cina, Berg.—Kurdistan. This herb fur- 
nishes the genuine Santonica-seeds (or rather flowers 
and fruits), as a vermifuge of long established use. 
Some other Asiatic species yield a similar drug. 
Artemisia Mutellina, Villars. — Alps of Europe.
