Oldeman in French Guiana was received on loan frwn Herb. Centre Cayenne, French Guiana has been poorly collected in recent times, a fact reflected in this collection. Nine of the lU species of Strychnos known to occur in that country (see 7a:8U, and note that S. eugeniifolia and S. oiapocensis were collected after this paper was published) were represented, and one, S, panurensis , is recorded for the first time. No noraenclatviral changes are proposed in this paper. Range extensions for ten species are noted, and a study of tendrils in the American members of the genus is presented.
