RESTORATION OF ODONIA, WITH ITS MEXICAN SPECIES. 



The genus Odonia was first described l>\ Bertoloni in L822 and 

 afterwards taken up by DeCandolle in L835 and Sprengel in L827. 

 Bentbam and Hooker, however, combined it with Galactia, where it 

 has since remained. It is true that many supposed species of ( ralactia 

 are congeneric with Odonia and this is probably the one reason why 

 the two genera have been combined. The true type of ( ralactia is the 

 large scarlet-flowered species from Jamaica long known as Galactia 

 pendxda but now as Galactia galactia. It is very different from all our 

 United State- and Mexican species in it- corolla. The Mexican species 

 of Odonia will he as follow-:
