in Extra-Tropical Countries. 151 



Eugenia Zeyheri, Harvey. 



South-Africa. A tree attaining about 20 feet in height. The 

 berries are of cherry-size and edible. The relative value of the fruits 

 of many Asiatic, African and American species of Eugenia remains 

 to be ascertained; many of them doubtless furnish also good timber, 

 and all more or less essential oil. All such, even tropical trees, 

 should be tested in warm tracts of the temperate zone, inasmuch as 

 many of them endure a cooler clime than is generally supposed. 



Euonymus atropurpureus, Jacquin. 



The "Waahoo" of Eastern North-America. A tall shrub, the 

 bark of which is used in medicine, and from it the Euonymin, an 

 oleo-resin as a cholagogue is prepared. To this species is closely 

 allied E. occidentalis (Nuttall) from Oregon and California. 



Euonymus Japonicus, Thunberg. 



Japan. This evergreen shrub can be used advantageously for 

 forming hedges; it is easily multiplied by layers and requires little 

 care in cultivation. 



Eupatorium purpureum, Linn4. : 



Eastern North-America. " Queen of the Meadows." A perennial 

 herb, easily naturalized; has come into medicinal use as a powerful 

 diuretic; so also E. perfoliatum L., the " Thoroughwort" or " Boneset"; 

 these with other species are also not unimportant as honey-plants j so 

 of the same order in N. America species of Actinomeris and Prenanthes. 



Eupatorium tinctorium, Grisebach. 



Paraguay. A shrub of remarkably prolific and vigorous growth 

 (E. H. Egerton). Competes almost with the indigo-plant for dye. 

 It can be stripped of its leaves four times a year without injury to 

 the plant. 



Eupatorium triplinerve, Vahl. (E. Ayapana, Ventenat.) 



Central America. A perennial somewhat shrubby herb, possibly 

 hardy in the warmer parts of extra-tropical countries. It contains 

 eupatorin and much essential oil peculiar to the plant. It stands 

 locally in renown as a remedy against ophidian poisons, and evidently 

 possesses important medicinal properties. A tanning extract is pre- 

 pared for the English market from this herb, which contains about 20 

 per cent, tannic acid. 



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 

 magnificent 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.
