or four times in a season, that it makes a coarse but nutritious hay, 

 and that the quantity of forage, which can be made from it, is enor- 

 mous; cattle and horses are fond of it, and the hay can be harvested 

 easily. 



Trisetum antarcticum, Trinius. 



New Zealand. Ascending to sub-alpine elevations. A perennial 

 lustrous grass, particularly fit for cool climes. According to Mr. 

 John Buchanan it keeps its ground well, becoming an important 

 element locally in the pasture-vegetation. The abundant natal 

 growth indicates, how easily the grass by dissemination could be 

 naturalized elsewhere. 



Tristania conferta, R. Brown. 



New South Wales and Queensland. A noble shady tree, attaining 

 a height of about 150 feet. It is not only eligible as an avenue-tree, 

 but also as producing select timber; ribs of vessels from this tree have 

 lasted unimpaired thirty years and more. Growth in height 20-30 

 feet at Port Phillip in twenty years. 



Trithrinax Acanthocoma, Dmde. 



Rio Grande do Sul, in dry elevations. A dwarf Fan-palm for 

 window- or table-decoration, attaining only a height of about 6 feet; 

 foliage not leathery. ' 



Trithrinax Brasiliensis, Martius. 



Rio Grande do Sul and Parana, Uruguay and Paraguay. A very 

 hardy palm, not tall. 



Trithrinax campestris, Drude.* 



Argentina, as far south as 32 40'. Height reaching about 30 feet. 

 One of the most southern of all palms. Content with even less 

 humidity than Chamaerops humilis. The leaves are almost of a 

 woody hardness and stiffer than those of any other palm (Drude). 

 Germination from seeds easy (Lorentz and Hieronymus). Another 

 species occurs in Southern Bolivia. 



Triticum junceum, Linn. (Agropyrum junceum, Beauvois.) 



Europe and North- Africa. A rigid coast-grass, with pungent 

 leaves and extensively creeping roots, requiring sea-sand for its per- 

 manent growth. One of the best grasses, to keep rolling sand-ridges 

 together, and particularly eligible, where cattle and other domestic 

 animals cannot readily be prevented from getting access. 



Triticum vulgare, Villars.* 



The Wheat. Indigenous to the Euphrates-regions, according to 

 A. de Candolle. Traced back more than 5,000 years as an Egyptian 

 and Chinese culture-plant; indeed the earliest lacustrine people in 

 Switzerland reared wheat in a stone-age (Heer). In many intra- 

 tropical countries, not too wet, wheat and barley can be grown as 

 winter-crop. In Japan wheat is of extraordinary precocity (Lartigne),
