SUPPLEMENTARY NOTES ON AMERICAN MENISPERMACEAE XIV NEOTROPICAL TRICLISIEAE AND ANOMOSPERMEAE B. A. Krukoff Consulting Botanist of Merck Sharp & Dohrae Research Laboratories, Rahway, N.J., and Honorary Curator of New York Botanical Garden. It is satisfactory that good steady progress is being made in our knowledge of both tribes. Since the latest paper of this series (Supplement XIII) was published, 65 new collections were examined, adding to our knowledge of several species. Extensions of range were noted for 9 species, and two species, namely Caryo -mene grand i folia and Anomospermum andersonii , are described as new. The prize collection is of a new genus, Cionomene jayarien -sis , with extraordinary stamina te flowers which have the inner 3 sepals fused for the most part into a solid column. Two excellent collections in mature fruit of Anomospermum reticulatum ssp. idroboi from Panama permitted Barneby and me to finally ascertain the identity of numerous collections from Costa Rica collected by Humberto Barquero M. on various occasions in 1970, 1971 and in 1977, First collection of Abuta steyermarkii in fruit and of Abuta aris -teguietae appear to back up our understanding that these two are distinct species. For their full understanding we need staminate specimens of both species which are still not known. The chemical work on neotropical Triclisiae and Anomosper-meae by Dr. Michael P. Cava and his associates continues. A new oxoaporphine alkaloid -splendidine -has been recently isolated from stem wood of Abuta rufescens Aublet .(l)lts structure was proved by total synthesis. The promising results on this project with cancer on behalf of the Cancer Institute are being followed; large samples, + 50 lbs, each, of Abuta rufescens , Sciadotenia toxifera and Abuta pahni were recently obtained by me and present-ly studied chemically by Dr, Cava. K. Thanikaimoni continues study of pollen. This study appears to be promising as there are several types of pollen in these tribes. The extensive paper on the wood anatomy of the two tribes by A. M. W. Mennega is still being revised by the author and unfortunately not yet published. Unexpectedly progress in the study of chromosomes was made. Seeds of several species were distributed to three institutions. At MO seeds did not germinate; at NY the technique in use was found not to be giving results with chromosomes of Menispermaceae which are very small and difficult to separate. Recently I re-ceived a communication from Pacific Tropical Botanical Garden in Hawaii to the effect that Dr, Carr succeeded in counting chromo-somes from rooting material of Elephantomene eburnea . These studies are of considerable interest as of the 16 known New World 239
