CainelliacetB have many affinities: 1. With polypetalous polyandrous bypogynous families with a 

 plurilocular ovary (see Ilypericinea; and Guttiferce). They scarcely differ from i.nnea;, to which they 

 are united by Cochlospennetf, except in their ovary with perfect cells, and their exstipulate leaves. They 

 approach Dipterocarpeat in the polysepalous calyx, the polypetalous hypogynous corolla with imbricate 

 aestivation, the polyandry, the several-celled ovary which is broadly sessile or slightly buried in the torus, 

 the exalbuminous seed, the woody stem and the alternate leaves ; but Dipterocarpea are separated by 

 their persistent and usually accrescent calyx, their one-celled and one-seeded fruit, their habit, and especi- 

 ally by their resinous juice. They have also some affinities with Tiliacece, which principally differ in the 

 valvate calyx. 2. With monopetalous families (see Ericinea, Styracea and Ebenaceee). They are further 

 connected with Sapotece through Eurya and 7 ernstroemia, whose corolla is monopetalous, imbricate, diplo- 

 or triplo-stemonous, the fruit a berry, the stem woody, and the leaves alternate and coriaceous; but 

 Sapotece have extrorse anthers. 



Cumdliacece principally inhabit tropical America and eastern Asia ; very few are met with in North 

 America, and one species only ( Visnca Moccanera) in the Canaries. 



Some species of Snurauja and Kielmeyera are mucilaginous and emollient. Gordonia contains an 

 astringent principle, and is used in tanning leather. The seeds of Camellia japonica, introduced into 

 Europe in 1739, are valued in eastern Asia on account of the fixed oil which they contain. Its leaves have 

 a slight tea-like scent. The most important species of this family is the Tea (Thea chuiensis), which some 

 authors place in the genus Camellia. Two centuries have not elapsed since Tea was first used in Europe, 

 and the annual importation now exceeds twenty-two millions of pounds. The stimulating property 

 of Tea is due to an astringent principle, an azotized substance called theinc, and especially a small
