THE BOTANIC GARDEN. 1^3 



channels of commerce; but the smaller species 

 would never be introduced, if their seeds were 

 not gathered by naturalists and transmitted to 

 botanic gardens. In this way we have obtained 

 the reseda, sent from Egypt by Granger in 1736 ; 

 the turnsole, from Peru by Joseph de Jussieu in 

 1740, and the silene bipartita, brought from Bar- 

 bary by M. Desfontaines in 1786. The same may 

 be said of the pretty Minorca sandwort, arenavia 

 balearicaj of the Mexican lopezia, which we 

 received from Spain some years ago ; of the 

 sweet-scented coltsfoot, tussilago, found on the 

 Pyrenees, and described by Yillars ; of the cacalia 

 sagittata, lately received from Java; and many 

 other plants now common in our flower-markets. 



The intervals left for new species, in replant- 

 ing the botanic garden, have in many instances 

 been filled up, especially by the accessions from 

 New Holland ; and probably ten years will 

 not elapse without the necessity of again en- 

 larging it.
