locally in renown as a remedy against ophidian poisons, and 

 evidently possesses important medicinal properties. A tanning 

 extract is prepared for the English market from this herb, con- 

 taining about 20 per cent, tannic acid. 



Eurotia lanata. Moquin. 



The "Winter-fat." From Oregon to New Mexico. A dwarf 

 saltbnsh, valued as holding out on pastures during the frosty 

 season [T. Watson.] 



Euryale ferox, Salisbury. 



From tropical Asia to Japan, ascending in Cashmir to 5,000 feet, 

 extending northward in Amur to nearly 46 N. Though less mag- 

 nificent than the grand Victoria Regia, this closely allied water-lily 

 is much more hardy, and would live unprotected in ponds and lakes 

 of a temperate climate. Though not strictly an industrial plant, it 

 is not without utility, and undergoes some sort of cultivation in 

 China for its edible roots and seeds. The leaves attain a width of 

 3 feet. 



Eustrephus 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 [Martius], an altitude higher than 

 is reached there by any other palm unless E. Haeiikeana and E. 

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

 as Minas Geraes in Brazil. 



Euxolus viridis. Moquin. (Amarantus 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. All easily naturalised. 



Excaecaria sebifera, J. Mueller. (Stillingia sebifera, Michaux.) 



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

 seeds constitutes the vegetable tallow, which is separated by steam- 

 ing. 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. It fruits as a rule abund- 

 antly. 



ZSxidia auricula Judae, Fries. (Hirneola auricula Judae, Fries.) 



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

 alone the quantity exported from Tahiti to China represented a 

 value ot 7,600 [Simmonds]. Doubtless this useful fungus is
