416 Select Plants for Industrial Culture and 



Rhns aromatica, Alton. 



North- America, from the Atlantic to the Pacific Ocean, north- 

 ward to Canada. A straggling bush. The aromatic foliage 

 important for medicinal purposes. 



Alms caustica, Hooker and Arnott. (Lithroea venenosa, Miers.) 



Chili, where it is called the Litre. A small or middle-sized tree, 

 the very hard wood of which is used for wheel-teeth, axletrees and 

 select furniture. The plant seems neither caustic nor otherwise 

 poisonous [Dr. Phillippi]. 



Rhus copallina, Linne. 



Eastern North- America, extending to Canada. A comparatively 

 dwarf species. This can be used for tanning. A resin for varnishes 

 is also obtained from this shrub. 



Rhus coriaria, Dodoens.* 



The Tanner's Sumach. Countries around the Mediterranean Sea, 

 extending to temperate Western Asia. The foliage of this shrub 

 or small tree, simply dried and reduced to powder, forms the 

 sumach of commerce. It isremarkablv rich in tannic acid, yielding 

 as much as 30 per cent., and is extensively used for the production 

 of a superior Corduan- or Maroquin-leather and pale-colored 

 leathers and dress-goods. Sumach allows the leather to carry 

 more grease [Bailment]. Price in Melbourne 15 to 30 per ton. 

 It thrives best in loose calcareous soils, and cannot endure stagnant 

 water. The strongest sumach is produced on dry ground. The 

 cultivation presents no difficulty. With us it has thriven well even 

 on the dry plains of the Wimmera-district. A gathering can be 

 obtained from suckers in the first year. The duration of sumach- 

 fields under manure extends to fifteen years. Sumach can also be 

 used for ink and various, particularly black dyes. Under favorable 

 circumstances as much as a ton of sumach is obtained from an acre. 

 Sumach from Melbourne-plants was shown already at the Exhibition 

 of 1863. During 1889 the import into Britain was 12,514 tons, 

 valued 140,517. 



Rhns cotinoides, Nuttall. 



Arkansas and Alabama. A tree, rising to 40 feet. The inner 

 bark and the wood valuable for yielding a yellow dye [C. Mohr]. 



Rhus CO tin as, Linne.* (Cotinus coggyria, Scopoli.) 



The Scotino. In the countries on the Mediterranean Sea, 

 extending to Hungary and to the Himalayas. The wood of this 

 bush furnishes a yellow pigment. The Scotino, so valuable as a 

 material for yellow and black dye, and as a superior tanning sub- 

 stance, consists merely of the ground foliage of this plant. It con- 

 tains up to 24 per cent, tannin. The plant endures the Norwegian 

 winters northward to lat. 67 56 ' [Prof. Schuebeler].
