Retiniphyllum speciosum (Benth.) Mueller- 
Argoviensis in Martius F]. Bras. 6, pt. 5 (1881) 10. 
The collection cited below matches the type very 
closely. The type was collected by Spruce near Sao 
Gabriel, below the confluence of the Rio Uaupés with 
the Rio Negro. In 1932, Ducke found this species in 
the nearby Rio Curicuriari (Ducke 24020). Schultes & 
Pires 9139 seems to represent the third collection of this 
endemic to be preserved in our herbaria.
