EUCALYPTUS TREES, 291 
Crategus Oxyacantha, L.—Europe, North Africa, 
North and West Asia. The ordinary hawthorn or 
Whitethorn. Recorded here as one of the most eligi- 
ble among deciduous hedge-plants. 
Crateegus parvifolia, Aiton.—North America. For 
dwarf hedges. Spines long, slender, sharp, and nu- 
merous. 
Crateegus pyracantha, Persoon. — The Firethorn. 
South Europe. Thisspeciesis evergreen. It is like- 
wise adapted for hedges, but slower in growth than 
hawthorn, but not difficult to rear. 
Crategus tomentosa, L.— North America. Fruit 
edible. By the species mentioned the list of Ameri- 
can hedgethorns is, probably, not yet exhausted. 
Crithmum maritimum, L.—The real Samphir. Sea- 
shores of Middle and South Europe, North Africa, and 
the Orient. A perennial herb. Settlers on the coast 
might readily disseminate and naturalize it. It is 
held to be one of the best plants for pickles, the young 
leaves being selected for that purpose. 
Crocus sativus, L.—The Dye-Saffron. South Europe 
and Orient. The stigmata of this particular autumnal 
flowering crocus constitute the costly dye substance. 
The best is collected from the flowers, just as they 
daily open in succession. At our stage of colonization 
it would not be remunerative to grow saffron com- 
mercially ; but as the plant is well adapted for our 
clime, it might be planted out into various unoccupied 
mountain localities, with a final view to naturalize it, 
and to render it thus available at a later period from 
native sources. 
Crotalaria juncea, L. —The Sunn Hemp. Indigenous 
to South Asia, and also widely dispersed through tropi-
