Astragalus gummifer, La Billardi^re. 



Syria and Persia. This shrub also yields a good kind of 

 Tragacanth. 



Astragalus hypoglottis, Linne. 



In the colder regions of Europe, Asia and North America. 

 This perennial plant is regarded as a good fodder-herb on 

 calcareous and gravelly soil, and would likely be of importance 

 for our alps. Of the enormous number of supposed species 

 of this genus (according to Boissier, not less than 750, 

 merely in Asia Minor and the adjoining countries) many 

 must be of pastoral value, like some of our closely-allied 

 Swainsonas, though they also may include deleterious species. 



Astragalus parnassi, Boissier (A. Cylleneous, Heldreich). 



Greece. This small shrub furnishes there almost exclusively 

 the commercial Tragacanth. It ascends to elevations of 7000' 

 feet, becomes therefore alpine. 



Astragalus strabiliferus, Boyle. 



Asiatic Turkey. The brown Tragacanth is collected from this 

 species. 



Astragalus verus, Olivier. 



Asiatic Turkey and Persia. This shrub furnishes the Takalor 

 or Smyrna Tragacanth, or it is derived from an allied species. 



Atalantia glauca, J. Hooker. 



New South Wales and Queensland. This desert-lemon is 

 mentioned here to draw attention to the likelihood of its 

 improving in culture, and to its fitness for being grown in arid 

 land. 



Atriplex hortensis, Linne. 



North and Middle Asia. The Arroche. An annual Spinage 

 plant. 



Atriplex nummularium, Lindley. 



From Queensland through the desert-tracts to Victoria and 

 South Australia. One of the tallest and most fattening and 

 wholesome of our pastoral salt-bushes, and although a native 

 plant even here highly recommendable for artificial rearing, 

 as the spontaneously growing plants, by close occupation of 

 the sheep and cattle runs, have largely disappeared, and 

 as this useful bush even here in many wide tracts does not 

 exist. 



Atriplex spongiosum, P. v. Mueller. 



Through a great part of Central Australia, extending to the 

 west coast. Available like the preceding, and like A. 

 halimoides, A. vesicarium, A. holocarpum and several other 

 native species for salt-bush culture. Unquestionably some of
