but springs again from dry spots after rain. It likes soil contain- 

 ing lime, prospers on poorer ground than Red Clover, is more 

 nourishing and better digested and less exhaustive to the soil. 

 Dressing with gypsum vastly enhances the value and productive- 

 ness of any clover-field. 



Trifolium resupinatum, Linne". 



The annual Strawberry Clover. From South Europe and North 

 Africa to Persia; also in the Canary Islands and Azores. Admitted 

 here, though annual, as this clover is cultivated with predilection 

 in Upper India ; of tall growth and succulent foliage. 



Trifolum spadiceum, Linne. 



Brown Clover. Europe, West Asia. Though only annual or bien- 

 nial, this has been recommended for wet sandy moorland, on which 

 it redisseminates itself with readiness. 



Trifolium subrotundum, Hochstetter. 



The Mayad Clover. North and Middle Africa, ascending to 9,000 

 feet. A perennial species, in its native countries utilised with 

 advantage for Clever culture. This by no means closes the list of 

 the Clovers desirable for introduction, inasmuch as about 150 well- 

 marked species are recognised, many doubtless of value for pasture. 

 But the notes of rural observers on any of these kinds are so spar- 

 ingly extant that much uncertainty about the yield and nutritive 

 value of various kinds continues to . prevail. Most Clovers 

 come from the temperate zone of Europe and Asia ; only 

 two are indigenous to the eastern of the United States of North 

 America, none occur in Australia, few are found in South Africa, 

 several in California and the adjoining countries, several also in 

 Chili ; no species is peculiar to Japan. 



Trigonella Fcenum Graecum, Linne. 



Countries on the Mediterranean Sea. The seeds of this annual 

 herb find their use in veterinary medicine. 



Trigonella suavissima, Lindley. 



Interior of Australia, from the Murray River and its tributaries to 

 the vicinity of Shark's Bay. This perennial, fragrant, clover-like 

 plant proved a good pasture herb. A lithogram, illustrating this 

 plant, occurs in the work on the "Plants Indigenous to Victoria." 

 Some of the many European, Asiatic, and African plants of this 

 genus deserve our local tests. 



Triphasia Aurantiola, Loureiro. 



South-East Asia. This shrub is worth cultivation for the exquisite 

 fragrance of its flowers. The fruits, though small, are of pleasant
