Tetrapteris styloptera Jusseiu
This little-known, yellow-flowered climbing bush
was first described in 1954 by Richard E. Schultes.
The Maku, who live on the Rio Tikie (Amazonia),
call it caapi (cf. Banisteriopsis caapi) and use it for

bark medicinally as a hemostatic (Schultes
Tetrapteris mucronata Cav., known as caapipinima,
also appears to be used for psychoactivepurposes (Schultes and Hofmann 1992, 66f.*).
