Naturalisation in Extra-Tropical Countries. 17 



a peculiar acid, which takes its name from the generic appellation 

 of the plant. It stimulates stagnant intestinal states, exercises 

 beneficial catamenial forces, alleviates haemorrhoidal sufferings, 

 used to be a domestic remedy in ague, and is not without tonic 

 value. Fitted for warrens and light sandy soil. Recommended by 

 many for sheep-pastures, but disregarded by Langethal. Found 

 indigenous in Norway as far as 71 10 ; N. [Schuebeler]. 



Achillea moschata, Wulfen. 



Alps of Europe. The " Genipi " or "Iva" of the Swiss. This 

 perennial herb ought to bear transferring to any other alpine 

 mountains. With the allied A. nana (Linne) and A. atrata (Linne) 

 it enters as a component into the aromatic medicinal Swiss tea. 

 A. fragrantissima (Reichenbach) is a shrubby species from the 

 deserts of Egypt, Turkey and Persia, valuable for its medicinal 

 flowers. 



Achras Sapota, Linne. (Sapota Achras, Miller.) 



The " Sapodilla-Plum '" of the West-Indies and Central America. 

 A fine evergreen tree, producing delicious fruit. Needs regions 

 free of frost. Yields also guttapercha. The bark possesses tonic 

 properties. Achras Australis, R. Brown ; (Sideroxylon Australe, 

 J. Hooker), a tree yielding also tolerably good fruit, occurs in New 

 South Wales and Queensland. Other sapotaceous trees, producing 

 table-fruit, such as the Lucuma mammosa (the Marmalade-tree), 

 Lucuma Bonplandi, Chrysophyllum Cainito (the Star-Apple), all 

 from West India, and Lucuma Cainito of Peru, might also be sub- 

 jected to trial -culture in sub-tropical forest- valleys ; so furthermore 

 many of the trees of this order, from which guttapercha is obtained 

 (species of Palaquium, Isonandra, Sideroxylon, Cacosmanthus. 

 Illippe, Mimusops, Imbricaria and Payenia), might prove hardy in 

 sheltered woodlands, as they seem to need rather an equable humid 

 and mild climate, than the heat of the torrid zone. 



Aciphylla g-lacialis, F. v. Mueller. 



Australian Alps. The root of this perennial herb is somewhat 

 aromatic, and is liked by pasture animals. It may prove of culinary 

 value. 



A co nit um Napellus, Linne. 



The ''Monk's Hood." In the colder parts of Europe and Asia, 

 extending to the Himalayas and also to arctic America, especially 

 in mountainous regions. A powerful medicinal plant of perennial 

 growth, but sometimes only of biennial duration, variable in its 

 forms. It was first introduced into Australia, together with a 

 number of other Aconites, by the writer. All the species possess 

 more or less modified medicinal qualities, as -well in their herbage 

 as in their roots ; but so dangerously powerful are they, that the 

 plants should never be administered except as prescribed by a
