Naturalisation in Extra-Tropical Countries. 47 



Anthemis nobilis, Linne. 



The true u Chamomile." Middle and Southern Europe, Northern 

 Africa. A well-known medicinal plant, frequently also used as 

 edgings for garden-plots. Flowers in their normal state are prefer- 

 able for medicinal use to those in which the ray florets are produced 

 in increased numbers. They contain a peculiar volatile oil and two 

 acids, similar to angelic and yalerianic acid. Hardy in Norway to 

 lat. 63 52' [Schuebeler]. Use of the flowers therapeutically indi- 

 cated in light nervous and spasmodic affections; they act also as a 

 diuretic, and are renowned in popular medicine variously otherwise. 



Anthemis tinctoria, Linne. 



Middle and Southern Europe, Orient. An annual herb. The flowers 

 contain a yellow dye. 



Anthistiria avenacea, F. v. Mueller. (Themeda avenacea, F. v. M.) 



Extra-tropical and Central Australia. A nutritious, perennial 

 pasture-grass. Called by Mr. Bailey " one of the most productive 

 grasses of Australia"; it produces a large amount of bottom-fodder, 

 and it has also the advantage of being a prolific seeder, while it 

 endures a hot, dry clime; grows to a height of over 6 feet. Mr. 

 C. J. Maclarland considers it for pastoral purposes superior to the 

 ordinary Kangaroo-grass. It is nearest allied to A. gigantea 

 Cavanilles (Themeda gigantea, Hackel) of tropical Asia and 

 Polynesia. 



Anthistiria Clliata, Linne" fil. (A. australis, R. Brown; Themeda triandra,. 



Forskael). 



The well-known " Kangaroo-grass," not confined to Australia, but 

 stretching through Southern Asia also and through the whole of 

 Africa ; perennial, nutritious, comparatively hardy, ascending to sub- 

 alpine elevations. In good seasons and in fair soil it will rise to over 

 man's height. Chemical analysis of this grass during its spring- 

 growth gave the following result : Albumen, 2'05 ; gluten, 4' 67 ; 

 starch, 0'69 ; gum, 1'67 ; sugar, 3'06 per cent. [F. v. Mueller and 

 L. Hummel]. Several species of Anthistiria occur variously dis- 

 persed from South-Africa to Japan, deserving introduction and 

 naturalisation in countries of warm-temperate or tropical climates. 



Anthistiria membranacea, Lindley. (Themeda membranacea, F. v. 

 Mueller. ) 



Interior of Australia. Esteemed as fattening; seeds freely 

 [Bailey]. Particularly fitted for dry, hot pastures, even of desert- 

 regions, but never tall. 



Anthoxanthum odoratum, Linne. 



The "Scented Vernal-grass." Europe, Northern and Middle 

 Asia, North- Africa. Found wild in Norway to lat. 71 7' [Schue- 

 beler]. Perennial ; not of great value as a fattening grass, yet
