THA'MNEA. (From thamnos, a shrub.

THE'A. Tea. (From teha, the Chi- 

 nese name for tea. Nat. ord., Theads 

 [Ternstrb'miaceaa]. Linn., IQ-Monadel- 

 phia 8-Polyandria.) 



Greenhouse, white - flowered, evergreen 

 shrubs. Cuttings of ripened young shoots, 

 taken off at a joint, and inserted in silver sand, 

 under a bell-glass, and placed in a close pit, 

 the glass being opened at night, to prevent 

 damping ; also by layers, from shoots thrown 

 up by the roots ; also, we believe, by grafting 

 the tenderer kinds on Viridis. Has the single 

 Camellia been tried ? Equal parts of fibry peat 

 and sandy turfy loam packed tight. Winter 

 temp., 38 to 48. As the roots run deep, they 

 thrive best when planted out in a cool conser- 

 vatory. Plants have survived many winters 

 round London in the open ground, with the 

 protection of a mat in cold weather. Then 



\ viridisii maintained by many to"be' the only 

 | tea-plant used by the Chinese.
