152 Select Plants for Industrial Culture 



Bustrephus Brownii, F. v. Mueller. 



East- Australia as far south as Gippsland. This climber produces 

 sweet though only small tubers, which however are probably capable 

 of enlargement through culture. 



Euterpe andicola, Brongniart. 



Bolivia. Ascends to 9,000 feet (Martins), an altitude higher 

 than is reached there by any other palm unless E. Haenkeana and E. 

 longivaginata (Drude). E. edulis (Martius) extends as far south as 

 Minas Geraes in Brazil. 



Euxolus viridis, Moquin. (Amamntus viridis, Linne".) 



Temperate and tropical regions of Europe, Asia and Africa. 

 Annual; quickly raised. Not without value as a spinage-plant. E. 

 oleraceus is a cognate plant. 



ExCJBCaria sebifera, J. Mueller. (Stittingia sebifera, Michaux.) 



The Tallow-tree of China and Japan. The fatty coating of the 

 seeds constitutes the vegetable tallow, which is separated by steaming. 

 The wood is so hard and dense, as to be used for printing-blocks ; the 

 leaves furnish a black dye. The tree endures slight night-frosts, 

 though its foliage suffers. 



Exidia auricula Judae, Fries. (Hirneola auricula Jtidae, Fries.) 



Widely spread over the globe. Of this edible fungus in 1871 alone 

 the quantity exported from Tahiti to China represented a value of 

 7,600 (Simmonds). Doubtless this useful fungus is amenable to 

 translocation and subsequent naturalization. We have it as indige- 

 nous in Australia also. 



Exomis axyrioides, Fenzl. 



South-Africa. A good salt-bush there for pastures (McOwan). 



Fagopyrum cyinosum, Meissner. 



The perennial Buck-wheat or rather Beech-wheat of the Indian 

 and Chinese highlands. Can be used with other species for spinage 

 and grain; also a blue dye may be obtained from its leaves. 



Fagopyrum emarginatum, Babington. 



Chinese and Himalayan mountains, where it is cultivated for its 

 seeds. Annual. 



Fagopyrum esculentum, Moench.* 



Central Asia, extending eastward to Manchuria, growing to an 

 elevation of 14,000 feet in the Himalayas. The ordinary Buck-wheat, 

 called Buch-Waizen in Germany, from the resemblance (in miniature) 

 of the seeds to Beech-nuts ; hence also the generic name. This 

 annual herb succeeds on the poorest land ; clayey soil yields more 

 foliage but less grain. The crushed amylaceous seeds can be con- 

 verted into a palatable and wholesome food by boiling or baking. 

 Starch has also recently been prepared from the seeds as an article of
