Description Of The Tree
Botanical Description
The tree is reported to develop a straight, cylindrical bole. It attains a height of about 25 m, with small buttresses.
Natural Habitat
Lonchocarpus lilloi is reported in the montane semideciduous subtropical forests of Bolivia, up to 1,000 m of altitude.
Non Timber Uses
L. lilloi is reported to have a high rotenone content (flavonoid) in the roots. Rotenone is unstable in light and heat and almost all toxicity can be lost after few days. It is very toxic to fish, and it has been used by native people over the centuries
