Naturalisation in Extra-Tropical Countries 63 



Astragalus venosus, Hochstetter. 



From Abyssinia to Central Africa. This perennial herb is sub- 

 jected to regular cultivation for fodder, known as " Hamat-Kochata " 

 [D. Oliver]. 



Astragalus verus, Olivier. 



Asiatic Turkey and Persia. This shrub furnishes the Takalor- or 

 Smyrna-tragacanth, or it is derived from an allied species. From an 

 Astragalus of S.W. Asia is obtained the Sarcocolla-gum [Dr. 

 L)ymock.] 



Astrebla pectinata, F. v. Mueller.* (Danthonia pectinata, Lindley.) 



New South Wales, Queensland, Northern and Central Australia, 

 in arid regions, always inland. A perennial desert-grass resisting 

 drought ; sought with avidity by sheep, and very fattening to them 

 and other pasture-animals. Seeding freely. 



Astrebla triticoides, F. v. Mueller.* (Danthonia triticoides, Lindley.) 



The "Mitchell-grass." Of nearly the same natural distribution as 

 the preceding, and equalling that species in value. Both so important 

 as to deserve artificial rearing even in their native country. Deep- 

 rooted. 



Atalantia glauca, J. Hooker. 



New South Wales and Queensland. This desert-lemon is men- 

 tioned here, to draw attention to the likelihood of its improving in 

 culture, and to its fitness in being grown in arid climes. 



Atriplex Capense, Moqum. 



South-Africa. There a valuable salt-bush of pastures [Prof. 

 MacOwan]. 



Atriplex cinereum, Poiret. 



From Eastern to Western Australia, along the extra-tropical coast. 

 A rather tall and bulky salt-bush, which supplies good fodder for 

 cattle, according to Mr. F. Turner. A. Halimus, L., of the shores of 

 the Mediterranean Sea extends northwards to the entrance of the 

 Loire, 47 N. 



Atriplex crystallinum, J. Hooker. 



South-Eastern Australia and Tasmania, on the brink of the ocean 

 and exposed to its spray. This herb vegetates solely in salty coast- 

 sands, which it helps to bind, like Cakile. In a special volume by 

 the author of this work, all the Australian Salsolaceae are litho- 

 graphically illustrated, with a view that the selected kinds may be 

 easily recognised for further pastoral distribution.
