the difference of leaf-form does not appear to be correlated with 
any other characters, it is impossible to define the various forms 
included rightly by Micheli under his variety diversifolia. The 
form known as S. chinensis, Sims (S. macrophylla, Bunge), is 
stated by Hance to be cultivated near Canton for the sake of its 
edible tubers.

[Sagittaria trifolia, Linn. Sp. Pl. ed. 1, p. 993, said to be from 
China, is founded upon the figure in Petiver's ‘ Gazophylacium,' 
t. 19. fig. 5, and is referred by Micheli (in DC. Monogr. Phan. 
iii. p. 67) to Sagittaria sagittifolia, var. diversifolia, Micheli. 
It must, however, be regarded as a very doubtful plant. The 
leaves are represented with very narrow lobes. |

specimens referred to.)
