of the Galapagos Archipelago. 217 



Galapagos have neither flower nor fruit. It approaches the R. Rehlun 



(Hook. & Arn.) of Chili. 



BoRRERiA, Meyer. 



The following species belong to DeCandoUe's second section, "floribus 

 in axillis subfasciculatis aut solitariis," and they all seem peculiar to the 

 small group of islands under consideration. The corollas are furnished with 

 a tuft of hair above the faux. The stipules have long cilia. The flowers and 

 fruit are small, and the seeds rough with depressed tubercles, but the latter 

 organs afibrd scarcely any character.
