Description:Distribution and Ecology - Brazil: Para: basin of Rio Curuatinga, Froes 31602; basin of Rio Jamundá, Black & Ledoux 50-10727; basin of Rio Tocantins, Froes & Black 24378 (Ma-ruba), 24453; basin of Rio Tapajos, Pires 3533 (US), 3721 (foz do Rio Juruena). Amazonas: basin of Rio Negro, Froes 29614 (US), 29641; basin of Rio Solimoes, Froes 26410 (lago de Badajos), Ducke 1109, Froes 23726 (both specimens are from the upper Rio Solimoes); basin of Rio Tonantins, Froes 25554. Peru. San Martin (Huahuiva to Sapasoa), Woytkowski 5508 (M).Distribution: Costa Rica (Puntarenas); Panama (Canal Zone); Colombia (Valle del Cauca and between Misay and Timbiqui) ; Peru (Loreto and San Martin); British Guiana (Essequibo), and Brazil. In Brazil it has been collected in the State of Para (basins of Rio Amazonas, of Rio Jamunda, of Rio Tocantins and of Rio Tapajos); in the State of Amazonas (in the basins of Rio Negro, of Rio Solimoes, of Rio Tonantins, of the middle Rio Jurua, of Rio Jutai, of the lower Rio Javari and of the upper Rio Solimoes); in the Territory of Acre (basin of Rio Acre) and in the State of Bahia. We have also placed with this species, with doubts, a sterile specimen (Krukoff 10936) from the basin of Rio Mapiri, La Paz, Bolivia.
Discussion:This is the first record of the species from the basins of Rio Tocantins and Rio Tapajos (Para) and of the basin of Rio Tonantins (Amazonas), Brazil, also from San Martin in Peru.
Pires 3721 is of interest as it has been collected near the boundary line of the State of Para with the States of Matto Grosso and Amazonas. Therefore this species doubtless occurs also in the State of Matto Grosso.
Local names: Su-Lija (San Martin, Peru).
The range of this species is very extensive. It is one of the six which are found on the Pacific coast of Colombia. For further details on this, see under S. panurensis.
It is satisfactory that Duckc’s description of its fruits made on the basis of material from Brazil (31: 31, 57), matches closely our description of its fruits which we made on the basis of Tonduz 7236 collected in Costa Rica (1: 294). For information on the position of this species in Ducke’s key made on the basis of fruit characters, see under S. rondeletioides.
Said to be worthless as an arrow-poison component (A. C. Smith 2837; basin of Shodikar Creek, Essequibo, British Guiana) (1: 295).
Fanshawe (34: 66) gives the following information on the local names, and on its distribution in British Guiana:
“Local names: Devildoer; kwabanaro (Arawak); kumarawa (Akawaio, Are-kuna, Patamona, Macushi).
“It occurs rarely in rain-forest in the upper Essequibo district.”
