come 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, U. 
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 Eiver 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, L. 
Central and North America. 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 is of inferior value for fodder. 
Triticum vulgar e, Villars.* 
The Wheat. Apparently arisen through culture from 
Aegilops ovata, L,, 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 (21 liyhernum, L.), the 
Winter Wheat or Unbearded Wheat ; 2. Var. aristatum 
{T. aestivum, L.), the Summer Wheat or Bearded Wheat; 
3. Var. adhaerens (T. Spelta, L.), Wheat with fragile axis 
and adherent grain. Metzger enumerates as distinct kinds 
of cultivated Wheat ; — 
T. ‘Vulga/re, Vill., which includes among other varieties the 
ordinary Spring Wheat, the Pox Wheat and the Kentish
