382 Select Plants for Industrial Culture 



rural observers on any of these kinds are so sparingly 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, a few are 

 found in South- Africa, a good number in California and the adjoining 

 countries, several also in Chili, no species is peculiar to Japan. 



Trigonella Fcenum Graecum, Linn. 



Countries on the Mediterranean Sea, Western and Central Asia. 

 The seeds of this annual herb find their use in veterinary medicine. 



Trigonella suavissima, Lindley. 



Interior of Australia, from the Murray-River and-fts tributaries to 

 the vicinity of Shark-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 species of this 

 genus deserve local tests. 



Trilliura erectum, Linn<$. 



" The Birthroot." Eastern North-America. This liliaceous plant 

 has found its way into the materia medica. 



Triodia exigua, Kirk. 



South-Island of New Zealand, at 1,200 to 3,000 feet elevation. 

 Forms naturally almost even plots, often many square-yards in extent; 

 the leaves are hard, short and shining; the compact growth of the 

 turf or sward prevents weeds and other grasses to encroach. It is 

 particularly to be recommended for croquet-lawns, never requiring 

 mowing (Prof. Th. Kirk). Should prove especially valuable in colder 

 countries for lawns, and may hold its ground also in hotter climes 

 through some irrigation. 



Triphasia Aurantiola, Loureiro. 



South-Eastern Asia. This shrub is worth cultivation for the 

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

 pleasant sweetness. The plant may also prove well adapted for 

 hedges. Glycosmis citrifolia, Lindley, and Claussena punctata, Oliver, 

 also East-Asiatic fruit-shrubs, may possibly show themselves hardy 

 in sheltered forest-regions of warm temperate climes. 



Tripsacum dactyloides, Linn<$. 



Central and Northern America; known popularly as a Gama- 

 grass. A reedy perennial grass, more ornamental than utilitarian. 

 It is the original Buffalo-grass, and attains a height of 7 feet, 

 assuming the aspect of maize. It seems of inferior value for feed, but 

 serves for binding sand. Prof. C. Mohr however regards it as a 

 valuable fodder-grass. The seeds are available for food. Howard, 

 speaking in Carolina of this grass, contends, that it may be cut three
