all the following results on the high authority of my friend 

 Dr. J. Hooker. I may premise that I indiscriminately col- 

 lected everything in flower on the different islands, and for- 

 tunately kept my collections separate. Too much confidence, 

 however, must not be placed in the proportional results, as 

 the small collections brought home by some other naturalists, 

 though in some respects confirming the results, plainly show 

 that much remains to be done in the botany of this group: 

 the Leguminosae, moreover, has as yet been only approxi- 

 mately worked out : 



Hence we have the truly wonderful fact, that in James 

 Island, of the thirty-eight Galapageian plants, or those found 

 in no other part of the world, thirty are exclusively confined 

 to this one island; and in Albemarle Island, of the twenty- 

 six aboriginal Galapageian plants, twenty-two are confined 

 to this one island, that is, only four are at present known to 

 grow in the other islands of the archipelago; and so on, as 

 shown in the above table, with the plants from Chatham and 

 Charles Islands. This fact will, perhaps, be rendered even 

 more striking, by giving a few illustrations: thus, Scalesia, 

 a remarkable arborescent genus of the Compositae, is con- 

 fined to the archipelago: it has six species: one from Chat- 

 ham, one from Albemarle, one from Charles Island, two from 

 James Island, and the sixth from one of the three latter 

 islands, but it is not known from which : not one of these six 

 species grows on any two islands. Again, Euphorbia, a mun- .
