SAPOTACEAE 
Pouteria Ucuqui Pires & R. E. Schultes in Bot. 
Mus. Leafl. Harvard Univ. 14 (1950) 87, tt. 20, 21, 22,23. 
This gigantic forest tree, the fruits of which are eagerly 
sought for food by the natives (Pires & Schultes Joc. cit.), 
has hitherto not been reported from such westerly local- 
ities in the Amazon basin. It is not uncommon in the 
middle and lower courses of the Rio Apaporis of 
Colombia. 
The following Indian names may now be recorded for 
Pouteria Ucuqui: 'Tukano=poo-pee-d; Kuripako=heé- 
ne-ree; Puinave=bee; Kubeo=pd-ko-ra; Maku (of Rio 
Piraparana)=fo0d-hee-ya. The Brazilian name ucuqut is 
known and used by many Indians and white settlers on 
the Colombian side of the boundary between Brazil and 
Colombia. Colombians in settlements where Brazilian is 
not understood or spoken use the term yucuw for the tree.

tama (above mouth of Rio Kananari) and vicinity. Alt. about 900
