Naturalisation in Extra-Tropical Countries. 143 



Corylus rostrata, Alton. 



North-America, both east and west. Never tall. Nut small, but 

 kernel sweet. C. Mandschurica (Maximo wicz), from the Amur- 

 region, is a closely allied species or perhaps only a variety. 



Corynocarpus Isevigata, Forster. 



The Karaka of New Zealand, also the principal forest-tree of the 

 Chatham-Islands, attaining a height of 60 feet. The wood is light, 

 and used by the natives for canoes. The pulp of the fruit is edible. 

 Cattle browse on the foliage. In rich irrigated soil the tree can be 

 adopted for very shady avenues. 



Corynosicyos edulis. (Cladosicyos edulis, J. Hooker.) 



Guinea. An annual cucumber-like plant, with edible fruits about 

 1 foot long and 3 inches in diameter. Referred recently by Cogniaux 

 to the genus Cucumeropsis. 



Cotoneaster bacillaris, Wallich. 



Uplands and highlands of India. Finally a small tree. This is 

 declared to be the best there for walking-sticks, especially alp-sticks. 



Crambe cordifolia, Steven. 



From Persia and the Caucasus to Thibet and the Himalayas, up 

 to 14,000 feet. The root and foliage of this Kale afford an esculent. 

 Flower-stems reaching 10 feet in height ; the long-stalked leaves 

 may measure more than 2 feet in width. The root bears severe frost 

 [Grorlie]. C. Kotschyana (Boissier) is an allied plant. 



Crambe maritima, Linne. 



Sea-Kale. Sandy coasts of Europe and North- Africa, in Norway 

 to nearly 60 N. A perennial herb ; the young shoots used as a 

 wholesome and agreeable vegetable. Should be naturalised, parti- 

 cularly on humid tracks of country, even for pastoral purposes. 



Crambe Tataria, Wulfen. 



From Eastern Europe to Middle Asia. Perennial. Leaves like- 

 wise used for culinary purposes. According to Simmonds the large 

 fleshy roots also form an esculent. Can be grown still at Christiania. 



CratsegUS sestivalis, Torrey and Gray. 



The Apple-Haw. South-Eastern States of North- America. The 

 small juicy fruit of an agreeable acid taste. 



Cratsegus apiifolia, Michaux. 



Eastern North- America. Highly serviceable for hedges.
