this voyage, when he notices the plant, calls it Tetragonia 

 cornuta. 



Thunberg found it growing wild in Japan, where it is 

 called Tsura Na, or Creeping Cabbage ; in his Flora Japonica* 

 he named it Tetragonia Japonica, but he subsequently^ cor- 

 rected himself, and referred his plant to T. expansa. 



Besides the works above mentioned, it has also been de- 

 scribed and figured by Scopoli4 by RoTH,§and by M. De 

 Candolle.|| Several of the writers which 1 have referred to 

 note the plant as biennial, but in our climate it certainly is 

 only an annual. 



From the experience which I have had in the cultivation of 

 the Tetragonia, in the present year, I can venture to recom- 

 mend the following treatment. The seed should be sown in 

 the latter end of March, in a pot, which must be placed in a 

 Melon frame ; the seedling plants, while small, should be set 

 out singly, in small pots, and kept under the shelter of a cold 

 frame, until about the twentieth of May, when the mildness 

 of the season will probably allow of their being planted out, 

 without risk of being killed by frost. At that time a bed 

 must be prepared for the reception of the plants, by forming 

 a trench two feet wide, and one foot deep, which must be 

 filled level to the surface, with rotten dung from an old Cu- 

 cumber bed ; the dung must be covered with six inches of
