  • Discussion

    The first lecord of the species from the State of Para, from the Territory of Acre, and from the basin of Igarape Jandiatuba, in the State of Amazonas. The specimens examined are all from the high forest on terra firme (some from "restinga alta” and “capoeira fechada”). It is a huge bush-rope. Schultes & Cabrera 19095 cited in Supplement VII (7a: 42) bears the wrong label and probably belongs with Schultes & Cabrera 19096. It is said on the label of Schultes & Cabrera 19095: “bracts red, flowers yellow.” All Prance’s collections are represented by samples of root bark which were sent to Prof. Marini-Bettolo for chemical studies.
