is also derived from a form of B. Napus. The rape should 

 be produced here as an agrarian produce, giving a rapid 

 return, wherever it should remain free of aphis. The 

 hardier turnips could be produced on our highest Alps, as 

 they are grown still witlmi the Arctic cii'cle, and, according 

 to Dr. J. Hooker, at a height of 15,000 feet in the Himalaya 

 mountains. 



Bromus asper, Murray. 



Europe, North and Middle Asia. A good perennial fodder 

 grass for wood-regions, but like Festuca gigantea late in the 

 season. 



Bromus erectus, Hudson. 



Eui^ope, North Africa. Important as a perennial nutritious 

 grass for dry limestone regions; much liked by cattle and sheep. 



Bromus unioloides, Humboldt.* {B. Schraderi, Kunth.) 

 Here called the Prairie Grass. From Central America it has 

 spread over many parts of the globe. The writer saw it 

 disseminated in the mountains of St. Vincent's Gulf as early 

 as 1847. It is one of the richest of all grasses, grows 

 continuously and spreads readily from seeds, particularly on 

 fertile and somewhat humid soil, and has proved as a lasting 

 and nutritious fodder-grass or pastm^e-grass one of our best 

 acquisitions. 



Broussonetia papyrifera, Yentenat. 



The Paper Mulberry. Islands of the Pacific Ocean, China, 

 Japan, perhaps only truly indigenous in the last-named 

 country. The bast of this tree or shrub can be converted 

 into very strong paper. It can also be used as a textile 

 fabric ; fui-thermore the fabrics made from it can be dressed 

 with linseed oil for waterproof coverings. In cultivation 

 the plant is kept like an osier. The leaves cannot be used 

 for silkworms. European fabrics have largely superseded the 

 clothing made of this plant in the South Sea Islands. 



Bucliloa dactyloides, Ton^ey.'-^ 



The true Buffalo-grass of Kansas. Dioecious, creeping, only 

 rising to half a foot or less. It is' extremely fattening, but 

 apt to be suppressed by coarser grasses on places where these 

 are not trampled out or kept down by the pasture animals. 



Buddleya Madagascariensis, Lamarck. 



Madagascar. Of the numerous species of Buddleya, the 

 most eligible for shelter copses on account of its great size 

 and always tidy appearance, as well as vigour and celerity of 

 growth. It is ever-flowering.
