 distinct than in most species. They are, however, in all cases very 

 variable.

 Gathered by Mr. Spruce in the moist forest at Barra do Eio Negro 

 in fruit in January, 1851, and again in flower in August, 1851, at the 

 mouth of the Rio Negro, where he found two varieties, one with pur- 

 plish-red and bluish-grey flowers, the other with white flowers and rather 

 shorter leaves.
