endemic to the ancient Venezuela-Guiana land-mass to 
which the isolated quartzitic hills of eastern Colombia 
belong. The discovery of this species in three additional 
localities in the Comisaria del Vaupés, always in associa- 
tion with the curious flora characteristic of these hills, 
indicates that it is indeed distributed over a wide area. 
In each of the localities for which it is now known, it is an 
extremely abundant element of the savannah vegetation. 
Cotomp1a: Comisaria del Vaupés, Rio Kubiyd (tributary of Rio

mouth. Quartzite base. Alt. about 800-900 feet. General location:

FLACOURTIACEAE 
Euceraea nitida Martius Nov. Gen. & Sp. 8 (1829) 
90, t. 238. 
Euceraea nitida was described from the Rio Japura of 
Brazil, but the type may have been collected in the ter- 
ritory now included in Colombia, probably in the region 
of the Cerro de La Pedrera. Its occurrence is widespread 
though very disrupted. A rare species in our herbaria, it 
appears to be associated with the remnant floras of the 
Venezuela-Guiana land-mass, ranging from an eastern- 
most station in Dutch Guiana (Tafelberg: Maguire 
24396a) to its westernmost one on Cerro Isibukuri in 
Colombia. 
Cotomp1aA: Comisaria del Vaupés, Rio Kananari (affluent of Rio 
Apaporis), Cerro Isibukuri, near summit. January 23-25, 1952, Rich- 
ard Evans Schultes § Isidoro Cabrera 15035.—Same locality and date.
