Naturalisation in Extra- Tropical Countries. 85 



Calodendron Capense, Thunberg. 



Eastern South- Africa. A large and handsome tree, called the 

 Wild Chestnut-tree by the colonists. Particularly fit for pro- 

 menades. Rate of growth in height at Port Phillip, where it was 

 first brought by the writer, about 1J foot in a year. Fresh seeds 

 readily germinate. 



Caly ptranthes aromatica, Saint Hilaire. 



South-Brazil. The flower-buds of this spice-shrub can be used 

 almost like cloves, the berries like allspice. Several other aromatic 

 species are eligible for test-culture. 



Calyptronoma Swartzii, Grisebach. 



West-Indies. A palm, reaching a height of 60 feet. Ascends 

 on tropical mountains to over 3,000 feet elevation. It yields the 

 " long thatch " of Jamaica, the foliage furnishing an amber-colored 

 roofing material, neater and more durable than any other used on 

 that island, lasting twenty years or more without requiring repairs 

 [Jenman]. The generic name Calyptrogyne takes precedence. 



Camelina sativa, Crantz. 



Middle and Southern Europe, temperate Asia. An annual herb, 

 cultivated for the oil of its seeds. It is readily grown after cereals, 

 yields richly even on poor soil, and is not attacked by aphides. Mr. 

 W. Taylor obtained 32 bushels of seed from an acre, and from this 

 as much as 540 Ibs. of oil. The return is obtained within a few 

 months. The seeds serve also as food for many kinds of cage-birds 

 [Dr. Rosenthal]. Hardy in Norway to lat. 70 [ Schuebeler] . 



Camellia Japonica, Linne. 



This renowned horticultural plant attains a height of 30 feet in 

 Japan. It is planted there on roadsides for shelter, shade and 

 ornament [Christie]. Out of its elements in the hottest and coldest 

 climes. The wood is used for superior xylography [Dupont]. 

 The seeds, like those of C. Sasaqua (Thunberg), are available for 

 pressing oil. C. reticulata (Lindley) from China is conspicuous 

 for its very large flowers, attaining sometimes 20 inches in cir- 

 cumference. Like C. Japonica it is hardy at Arran, flowering 

 there far more freely [Rev. D. Landsborough]. In England a very 

 large plant of C. reticulata, reared in Mr. Byam Martin's conser- 

 vatory, had in October, 1848, removed from it 2,600 flower-buds, to 

 allow for April, 1849, about 2,000 flowers to come to perfection [Sir 

 W. Hooker]. 



Camellia Thea, Link.* (Thea Chinensis, Linne). 



The Tea-shrub of South-Eastern Asia, said to be indigenous also 

 to some localities of Japan, for instance Surugo, traced as spon- 

 taneous as far as Manchuria [Fontanier], also in Yunan, Khasya-
