in Extra- Tropical Countries. 35 



Anthyllis vulneraria, Linne. 



The Kidney-vetch. All Europe, Northern Africa, Western Asia. 

 This perennial herb serves as sheep-fodder, and is particularly recom- 

 mended for calcareous soils. It would also live in any alpine region. 

 Indigenous in Norway as far north as lat. 70 (Schuebeler). 



Apios tuberosa, Moench. 



North-America. A climber with somewhat milky juice. The 

 mealy tubers are edible. 



Apium Chilense, Hooker and Arnott. 



Western Extra-tropic temperate America. A stouter plant than 

 the ordinary celery, but of similar culinary use. 



Apium graveolens, Linne. 



The a Celery." Europe, Northern Africa, Northern and Middle 

 Asia. Grows in Norway to lat. 70 (Schuebeler). It is here merely 

 inserted with a view of pointing out, that it might be readily natural- 

 ized anywhere on sea-shores. The wild plant is however by some 

 considered unwholesome in a raw state. The fruitlets are occasionally 

 utilized for condiment. Seeds will keep for several years. 



Apium prostratum, La Billardiere. 



The Australian Celery. Extra-tropical Australia, New Zealand, 

 Extra-tropical South- America. This also can be utilized as a culinary 

 vegetable. 



Apocynum cannabinum, Linne". 



North- America. Locally known as " Indian Hemp." A perennial 

 herb. This is- recorded among plants yielding a textile fibre. A. 

 androsaemifolium (Linne) yields medicinally the " Bitter Root " of 

 the United States, that of A. cannabinum being likewise medicinally 

 valuable. 



Aponogeton crispus, Thunberg. 



From India to New South Wales. The tuberous roots of this 

 water-herb are amylaceous and of excellent taste, though not large. 

 The same remarks apply to A. monostachyos (Linne fil.) and several 

 other species, all from the warmer regions of the eastern hemisphere. 



Aponogeton distachyos, Thunberg. 



South- Africa. This curious water-plant might be naturalized in 

 ditches, swamps and lakes, for the sake of its edible tubers. The 

 scented flowering portion of this plant affords spinage. 



Aquilaria Agallocha, Roxburgh. 



Silhet and Assam. A tree of immense size. It furnishes the 

 fragrant calambac or agallochum-wood, known also as aggur or tug- 

 gur or the aloe-wood of commerce, famed since ancient times. The 

 odorous portion is only partially distributed through the stem. This 

 wood is also of medicinal value.
