Mr. Spruce found this species abundantly on the right bank of the 

 Eio Negro, opposite Uauanaca, in December, 1851, looking at a short 

 distance like a bright blue Campanula, The dried specimens resemble 

 so much Martius' figure of his J, ayigustifolius^ or J. ienuifoUuSy Spreng., 

 that one would have been tempted to identify them with that species, 

 were it not for the colour of the flower, the shape of the stigmate, and^ 

 the widely different station.
