BoRAGINEjE. 



Galapagoa, genus novum. 



Calyx 4-5-partitu8, laciniis linearibus. Corolla infundibuliformis, tubo lato, limbo 5-fido 

 patente, fauce nuda. Stamina 5, inclusa, imo corollae tubo inserta. Ovarium 4-locu- 

 lare. Stylus terminalis, ad basin usque bipartitus ; stigmata 2, obtusa. Semina pendula ; 

 albumine parco, carnoso; cotyledonibus planis; radicula majuscula, supera. 



Genus Ehretiearum, inter Coldeniam et Rhabdiam (suadente clariss. Bentham) medium, oh 

 stylum 2-partitum staminaque fundo corolla inserta singular e. 



Herbae Insularum " Galapagos," hlspido-piloscB. Qia.\Ats prostrati, ramosissimi. Folia alterna, 

 coriacea, versus apices ramulorum densissime confer ta. YXoves parvi, in axillis foliorum 

 omninb sessiles, valde inconspicui. 

 A highly remarkable genus, and abundantly distinct from any other among 



Boraginece. Though allied to the South American forms, especially Coldenia 



from Peru, and Rhabdia, a Brazilian genus, it would hitherto appear to be 



quite confined to this curious group of islands.
