44 Select Plants for Industrial Culture and 



recommended for calcareous soils. Comparable as regards nutrition 

 next to Red Clover, but suitable also for sandy soil too poor for 

 Red or White Clover ; for pasture it lasts three or four years [Dr. 

 Stebler]. It would also live in any alpine region. Indigenous in 

 Norway as far north as lat. 70 [Schuebeler]. 



Apios tuberosa, Moench. 



North-Eastern 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 " Celery." Europe, Northern Africa, Northern and Middle 

 Asia, North-Western America. Grows in Norway to lat. 70 

 [Schuebeler]. It is here merely inserted with a view of pointing 

 out, that it might be readily naturalized anywhere on sea-shores. 

 The wild plant is however by some considered unwholesome in a 

 raw state. The fruitlets are occasionally utilized for condiment. 

 Seed will keep for several years in cool climes, and it will ripen 

 even in the hottest and driest regions of Australia under horticul- 

 tural care. Much used by the ancients for wreaths. 



Apium prostratum, La Billardiere. 



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

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

 culinary vegetable, but not in a raw state. 



Apocynum cannabinum, Linne. 



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

 nial 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 medi- 

 cinally valuable. Both plants bear the clime to 60 N. lat. in Nor- 

 way [Prof. Schuebeler]. The therapeutic value depends on the 

 Apocynin, a potent diaphoretic solvent and laxative, also as an 

 eliminator, particularly advocated in hydrops, employed also in 

 gout. 



Aponogreton 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 til.) and several 

 other species, all from the warmer regions of the Eastern hemi- 

 sphere.
