Trade Name

Quina blanca

Scientific Name

Lonchocarpus lilloi (Hassl.) Burkart

LEGUMINOSAE

Common Names

Quina Blanca (Bolivia)

Scientific Name Synonyms

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
