Mr D. Don on the Characters of Darwinia, Sfc. 89 



jtedunculati, pendiUi, racemosi. Racemus laoms, oppositifolius. Calyx ruber, 

 apice pallidus. Corolla flava, limbo viridi. Capsula magna, ItBvigata. 



This genus is here hmited to include the E. viridis of Ruiz 

 and Pavon, and the E. hngiflorus of Humboldt and Bon- 

 pland, both being natives of Peru ; but the E. scaber differing 

 so essentially in the structure of its anthers, and having likewise 

 a different formed corolla and calyx, is here separated as a distinct 

 genus. It is probable that Chile contains several species of the 

 latter genus, as the plant of Ruiz and Pavon appears different 

 from the one cultivated in the gardens, of which an excellent de- 

 scription and figure will be found in the Botanical Register ; but 

 my materials are at present insufficient to decide this point. These 

 genera, together with Tourretia are clearly referable to the 

 Bignon'iacecE, of which they appear to me to constitute an oscu- 

 lant group, connecting that family with the CobcBacecB.
