expresses a doubt as to the identity of the two, but Hemsley, in 

 his recent flora of China, regards them as the same. The Yon- 

 soi, as we have grown it, has leaves rather more finel)^ cut than 

 the common coriander, and the flowers are somewhat different in 

 appearance. But in horticultural value t^ie two are not unlike. 



SUMMARY. 



Various garden vegetables have been introduced into this coun- 

 trj^ by the Chinese, some of which are worthy a place in American 

 gardens. 



The best known, and perhaps the most valuable of these new 

 vegetables, is the Pe-T.sai, or so-called Chinese cabbage. This 

 plant bears a loose lettuce-like head of crisp leaves, which may 

 be used in all the fashions in which cabbage is served. This 

 plant requires a cool and moist soil in which to make its best 

 growth. It is essentially an autumn vegetable. 



The Chinese mustard is an excellent plant for greens and pro- 

 duces an enormous amount of herbage. Its culture demands the 

 same attention as that advised for Pe-Tsai. 



California Peppergrass appears to be a finely cut-leaved form of 

 a mustard long known in old gardens, but not described either in 

 American botanies or gardening books. It is one of the best of 

 all plants for earl}^ spring greens. Although the species is culti- 

 vated in China and Japan, it does not appear to have been inde- 

 pendently introduced from those countries in recent jxars. It is 

 not known how or when the plant first came into this countr3^ 



Other mustard-like plants recently introduced from China are 

 the Pak-Choi, used as greens and for the white thick leaf-stalks ; 

 and the Tuberous-Rooted Mustard, grown for its small turnip-like 

 root. These plants possess less merit for American gardens than 

 the foregoing species. 



Of the various squash-hke plants introduced by the Chinese, 

 the best is probably the Wax Gourd or Zit-kwa. The fruit of 

 this is excellent for conserves. The plant is of easy culture, but re- 

 quires a long season. 



The La-kwa or Momordica has more merit as a curiosity and
