538 Select Plants for Industrial Culture and 



Trifolium rubens, Linn. 



Middle and Southern Europe, Middle Asia. A perennial Clover, 

 big in all its parts, attaining a height of 2 feet, the spikes up to 2J 

 inches long. Fond of calcareous soil, particularly in forest-lands, 

 therefore especially a feed-plant for forest game. 



Trifolium spadiceum, Linn6. 



Brown Clover. Europe, Western Asia. Perennial. This has 

 been recommended for wet sandy moorland, on which it gets dis- 

 seminated with readiness. 



Trifolium subrotundum, Hochstetter. 



The Mayad-Clover. Northern and Middle Africa, ascending to 

 9,000 feet. A perennial species, in its native countries utilised with 

 advantage for clover-culture. 



This by no means closes the list of the clovers variously desirable 

 for introduction, inasmuch as, according to Bentham and Hooker, 

 about 150 well-marked species are recognised, many doubtless of 

 value for pasture. Boissier admits 114 species for the countries at 

 the Mediterranean Sea. But the notes of 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 twa 

 are indigenous to the Eastern of the United States of North- America, 

 none occur in Australia, 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. 



Trifolium subterraneum, Linn6. 



Countries at the Mediterranean Sea, reaching also the South of 

 England. This small plant is admirably adapted to suppress annual 

 weeds such as the Cryptostemma calendulaceum (Cape Weed) on 

 pastures [J. Farrell]. Affords good feed, takes hold of the ground 

 with singular quickness ; pastures of this carry a good lot of stock 

 [F. Madden]. 



Trifolium tomentosum, Lmn. 



Countries at the Mediterranean Sea. Though annual, it struggles 

 through the dry season, affording even in autumn some parched 

 feed. 



Triglochin procera, R. Brown. 



Widely distributed through Australia. This remarkably large 

 perennial is worthy of dissemination in and around swamps, as cattle 

 feed on it with avidity ; it produces small edible tubers.
