 almost impossible to avoid breaking some of their attach- 

 ments, the space was carefully examined and yielded ninety 

 legumes of varying size. Thus from these twenty plants 

 the grand total of terrestrial legumes was three hundred 

 and twenty. 



In a plot of ground where plants were separated as much 

 as possible, there was a large yield of terrestrial legumes, 

 but comparatively few aerial, none of which resulted from 

 purple flowers. Although the soil was quite rich, it was 

 constantly exposed to sun, and moisture was not abundant. 

 All of the plants were low, wound somewhat around each 

 other, but rather trailed on the ground. This may have 

 been partly due to the winds which blew quite usually over 

 the special part of the Garden where these grew. 



Three very vigorous plants deserve notice, and were so 

 arranged that each could be lifted out with the mass of soil 

 still clinging around the roots. Careful examination
