Discussion
Local name: Á-da-pee (Karipako), ee-nee-má Karapaná), koo-ee-et (Maku), cuit (Macuna), limanaju (Lesana, subtribe of the Macunas), ua-oó-nee-ma-ma (Makune), yawn-yot, yow-yoo (Puinave), wau-reé-ko-a (Tanimuka), ha-raupee, ha-ra-pa (Yakuna). These Indian names are cited as they appear on the labels of specimens collected by Schultes A Cabrera, also of Garcia-Barriaga in the basin of Rio Apaporis, Amazonas/Vaupés, Colombia. In Ducke’s key made on the basis of fruit characters, this species comes together with S. Mitscherlichii (31: 56). According to Schultes, this species is used in curare by the Kofán Indians on the Rio Putumayo in Colombia (6: 14; 7: 7) Fanshawe (34: 66) gives the following information on the local names, on the field characters of this bush-rope, on its distribution in British Guiana and on its alkaloids, probably on the authority of Dr. King: “Local names: Devildoer; kwabanaro (Arawak); urariballi (Arawak); oraridan (Carib); kumarawa (Akawaio, Arekuna, Patamona, Macushi). “A canopy climber to 12 inches in diameter; bark dark, reddish-brown, rough, slash pale crimson, hard, brittle and thin as in S. diaboli). “It occurs occasionally, chiefly in mora forest on mora trees in the North Central and North East districts, the Pakaraima Mountains, and the far interior. “The total alkaloids have a convulsant, strychnine-like action; hence its use as an aphrodisiac.” As per King, the alkaloid content of this species was found to be “+ + + + ” (74). In another paper by the same author (75), the alkaloid content is given as “+ + +,” curare action “none.” The author states: “Of the other species recorded in the table, S. Erichsonii is very rich in alkaloids, but they seem to resinify with great ease and may need a special technique for their characterization.” This work was done on For. Dept. 2284 (from British Guiana) which we cite under S. Erichsonii (4: 344). It is not known which part of the plant was used for this work, presumably stem bark. For information on the pharmacological actions of total alkaloids of this species as found by Dr. Ranyard West, see under S. diaboli.
