corae from the temperate zone of Europe and Asia ; only 

 two are indigenous to the eastern of the United States of 

 North America, none occurs 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 Foenum Graecum, L. 



Countries on the Mediterranean Sea. The seeds of this 

 annual herb find their use in veterinary medicine. 



Trigonella suavissima, Eindley. 



Interior of Australia, from the Murray River and its tribu- 

 taries 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 Euro- 

 pean, Asian and African plants of this genus deserve our 

 local tests. 



Tripsacum dactyloides, E. 



Central and North America. A reedy perennial grass, more 

 ornamental than utilitarian. It is the original Buffalo- 

 Grrass, and attains a height of 7 feet, assuming the aspect of 

 Maize. It is of inferior value for fodder. 



Triticum vulgare, Villars.* 



The Wheat. Apparently arisen through culture from 

 Aegilojps ovata, E., and then a South European, North 

 African and Oriental plant. This is not the place, to enter 

 into details about a plant universally known. It may there- 

 fore suffice merely to mention, that three primary varieties 

 must be distinguished between the very numerous sorts of 

 cultivated Wheat: 1. Var. muticum (T. hybernwn, L.), the 

 Winter Wheat or Unbearded Wheat ; 2. Var. aristatum 

 {T. aestivum, E.), the Summer Wheat or Bearded Wheat; 

 3. Var. adhaerens (T. Spelta, E.), Wheat with fragile axis 

 and adherent grain. Metzger enumerates as distinct kinds 

 of cultivated Wheat t— 



T. vulgare, Vill., which includes among other varieties the 

 ordinary Spring Wheat, the Fox Wheat and the Kentish
