Supplementary Notes on the American Species of Strychnos. VII. Mem (12)2

Our last serial paper on Strychnos appeared in print in September, 1950 (7). Since then, abundant new collections have become available. The collections examined extend our knowledge of many species previously known from incomplete material; extensions of ranges are noted, and it has been found desirable to arrange the species according to their taxonomical relationship, and rewrite all the keys.
