Fruits resemble those of S. macrophylla.

Discussion:This bush-rope of modest dimensions is usually found on the immediate shores of creeks and small rivers. It is known from Peru (Loreto, Rio Nanay), Colombia (Yaupes and Amazonas) and the State of Amazonas, Brazil (Igarape Belem, Rio Capitari and Lago de Badajos in the basin of Rio Solimoes, Rio Juruema in the basin of Rio Jutai and in the basin of Rio Javari). For a discussion of this variety as well as others in the S. mitscherlichii-complex, see under S. mitscherlichii var. mitscherlichii (p. 45). The collector’s note on Schultes & Cabrera 16271 reads: “poison (curare) vine” (7a: 54).
