Elymus arenarius, L.* 
The Sea Lyme-Grrass. Europe and North Asia, on sand- 
coasts. One of the most important and vigorous of grasses 
for binding drift-sand on the sea shores. The North 
American E. mollis, Trinius, is allied to this species. 
Elymus condensatus, Presl. 
The Bunch- Glrass of British Columbia and California. 
This is favorably known as adapted for sandland. 
Ervum Lens, E. {LeJis esculenta, Moench.) 
Mediterranean regions, Orient. The Lentil. Annual, 
affording in its seeds a palatable and nutritious food. 
Euclea myrtina, Burchell. 
South Africa. Berry small, black, but edible. To us this 
plant would hardly be more than an ornamental bush. 
Euclea undulata, Thunberg. 
South Africa. Berry small, red, edible. Other shrubby 
species from the same portion of the globe yield also 
esculent fruits, which under superior culture may vastly 
improve. 
Erythroxylon Coca, Lamarck.* 
Peru. This shrub is famed for the extaraordinarily stimu- 
lating property of its leaves, which pass under the names of 
Spadic and Coca. They contain two alkaloids, Cocain and 
Hygrin, also a peculiar tannic acid. Whether any of the 
many other species of Erythroxylon possess similar pro- 
perties seems never yet to have been ascertained. 
Eupatorium triplinerve, Vahl. {E. Ayapana, Ventenat.) 
Central America. A perennial somewhat shrubby herb, 
possibly hardy in the warmer parts of our Colony. It is 
used as a medicinal plant, also as an alexipharmic. It con- 
tains Eupatorin and much essential oil, peculiar to the 
plant. 
Fagopyrum cymosum, Meissner. 
The perennial Buck- Wheat or rather Beech-Wheat of the 
Indian and Chinese Highlands.
