no. 8 (1946) 9), Solanum sessiliflorum, known as cubiu, is 
common in the Brazilian Estado do Amazonas, especially 
in its westernmost part along the Solimodes River, where 
it is found both cultivated and wild. The fruits are said 
to be edible. There is, he states, another species of Sola- 
num with small, edible fruits also known as cubiu along 
the Solimdes: we believe that this species, which Ducke 
did not identify, may possibly be Solanum platyphyllum. 
Sendtner (in Martius Flora Brasiliensis pt. 6 (1846) 
73) cited Solanum sessilifiorum from Para, at the mouth 
of the Amazon River, under the common name cudbio. 
We have no evidence that So/anum sessiliflorum is cul- 
tivated in Colombian territory, but it naturally must be 
expected there if it be common in the western part of the 
Brazilian Amazon. 
It should be pointed out that the vernacular Nengatt 
name cubiyii is applied in the Colombian Vaupés to sever- 
ul species of Solanum: WS. daeimitante, S. straminifolium, 
S. Topiro; it seems to be a rather generic name used tor 
a number of species of Solanum with edible fruits. Near 
Mitu, there is a river, an affluent of the Vaupés, called 
Rio Kubiyu.
