Cratsegus parvifolia, Alton. 



North America. For dwarf hedges. Spines long, slender, sharp, 

 and numerous. 



Cratsegus pyracantha, Persoon. 



The Firethorn. South Europe. This species is evergreen. It is 

 likewise adapted for hedges, but slower in growth than Hawthorn, 

 altogether not difficult to rear. 



Cratsegus tomentosa, Linne. 



North America. Up to 20 feet high. Fruit edible. By the 

 species mentioned the list of American Hedgethorns is probably not 

 yet exhausted. 



Crithmum maritimum, Linne. 



The real Samphire. Sea-shores of Middle and South Europe, North 

 Africa and the Orient. A perennial herb. Settlers on the coast 

 might readily disseminate and naturalise it. It is held to be one 

 of the best plants for pickles, the young leaves being selected for 

 that purpose. 



Crocus sativus, Linne. 



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 any early stage of colonisation it would 

 not be remunerative to grow saffron commercially ; but as the plant 

 is well adapted for many extra-tropical countries or for high eleva- 

 tions within the tropical clime, it might be planted out into various 

 unoccupied mountain localities with a final view to naturalise it, 

 and to render it thus available at a later period from native sources. 

 Noted as a bee-plant already by the ancients (Muenter). 



Crocus serotinus, Salisbury. (C. odorus, Bivona.) 



South Europe. This species also produces saffron rich in pigment. 

 The bulbs of several are edible. 



Crotalaria Burhia, Hamilton. 



Beluchistan, Affghanistan, Scinde. This perennial herb grows in 

 arid places, and yields, like the following, Sunn fibre. 



Crotalaria juncea, Linne. 



The Sunn Hemp. Indigenous to South Asia, and also widely dis- 

 persed through tropical Australia. An annual herb, rising under 

 favourable circumstances to a height of 10 feet. In the colony of 

 Victoria Sunn can only be cultivated in the warmest and moistest
