Tephrosia is a genus of
flowering plants in the family
Fabaceae. It is widespread in both the Eastern and Western Hemisphere, where it is found in tropical and warm-temperate regions.[4]
The generic name is derived from the
Greek word τεφρος (tephros), meaning "ash-colored," referring to the greyish tint given to the leaves by their dense
trichomes.[5]Hoarypea is a common name for plants in this genus,[6] along with goat's rue and devil's shoestring.[7]
Uses
Many species in the genus are poisonous, particularly to
fish, for their high concentration of
rotenone. The black seeds of Tephrosia species have historically been used by indigenous cultures as
fish toxins.[7][8][9][10] In the last century, several Tephrosia species have been studied in connection with the use of
rotenone as an
insecticide and
pesticide.
