EUCALYPTUS TREES. 411 
Asia, extending eastward to Japan. This annual herb 
is cultivated as far as 42° N. L. The oil, fresh ex- 
pressed from the seeds, is available for table use. One 
of the advantages of the culture of this plant consists 
in its quick return of produce. The soot of the oil is 
used for China-ink. 
Sesbania aculeata, Persoon.—The Danchi. Intra- 
tropical and sub-tropical Asia, Africa, and Australia. 
This tall annual plant has proved adapted for our des- 
ert regions. It yields a tough fiber for ropes, nets, 
and cordage, valued at from £30 to £40 for the ton. 
Several congeneric plants can be equally well utilized. 
Shepherdia argentea, Nuttall.— The Buffalo-berry. 
From the Missouri to Hudson’s Bay. This bush bears 
red, acidulous, edible berries. 
Sison Amomum, L.— Middle and South Europe. 
An herb of one or two years’ duration. It grows best 
on soil rich in lime. The seeds can be used for con- 
diment. 
Smilax officinalis, Humboldt. — New Granada and 
other parts of Central America. This climbing shrub 
produces at least a portion of the Columbian sarsapa- 
rilla. 
Smilax medica, Cham. and Schl. — Mexico. This 
plant produces mainly the sarsaparilla root of that 
country. 
Smilax papyracea, Duhamel. — Guiana to Brazil. 
The origin of the principal supply of Brazilian sarsa- 
parilla is ascribed to this species, although several 
others of this genus, largely represented in Brazil, 
may yield the medicinal root also. In our fern - tree 
gullies these plants would likely succeed in establish- 
ing themselves. Similax Australis, R. Br., extends
