512 Select Plants for Industrial Culture and 



infected by blight, checks materially the spread of insects, which 

 cause the disease. The most destructive potato-grub is Lita Sola- 

 nella. The Colorado-beetle, injurious to the potato-crop in North- 

 America, is Doryphora decemlineata. Already many years ago 

 Professor Thomas Meehan of Philadelphia recommended Paris Green 

 as a protective of the Potato-plant against the Colorado-bettle. 



Solanum Uporo, Dunal. 



In many of the islands of the Pacific Ocean. This shrub has 

 proved hardy at Port Phillip. The large red spherical berries can be 

 used like tomatoes. The leaves, macerated in cold water, render it 

 quickly mucilaginous, and the liquid thus obtained is regarded as 

 valuable against dysentery [Rob. MacDougall]. 



Solanum vescum, F. v. Mueller. 



The Gunyang. South-Eastern Australia, extending to Tasmania. 

 A shrub, yielding edible berries, which need however to be fully ripe 

 for effecting absence of deleterious properties. 



Sophora Japonica, Linne". 



A deciduous tree of China and Japan, resembling the Laburnum, 

 at length 60 feet high. Hardy in Middle Europe. Wood hard and 

 compact, valued for turners' work. All parts of the plant purgative; 

 the flowers rich in yellow dye, used for silk. The variety pendula, 

 desirable for cemeteries ; when trained as a creeper, it has few rivals 

 in handsomeness. 



Sophora tetraptera, J. Miller. 



New Zealand, Lord Howe's Island, Juan Fernandez Island, Chili, 

 Patagonia. The "Pelu" of the latter countries. A small tree, with 

 exceedingly hard and durable wood, which can be used for cog-wheels 

 and other select structures. Trunk exceptionally attaining a diameter 

 of three feet. The wood differs much from that of S. Tomairo of the 

 Easter-Island [Dr. Philippi]. 



Spartina cynosuroides, Willdenow. 



Eastern part of North-America, there often called Prairie-grass. 

 A perennial grass of fresh-water swamps ; it can be utilised for 

 fodder, and its value as paper-material seems almost equal to that of 

 Esparto. Emits shoots copiously, hence is recommended by Bouche 

 for binding maritime driftsands, covering the ground densely with 

 its persistent rigid foliage. 



Spartina juncea, Willdenow. 



Salt-marshes of North-America. A grass with creeping roots ; it 

 can be utilised to bind moist sand on coasts. A tough fibre can readily 

 be obtained from the leaves. S. polystachya (Willdenow) is a stately 

 grass, adapted for saline soil ; it is also a North- American species. 

 S. juncea and S. cynosuroides extend to Canada [J. Macoun].
